13 Chapter 1: New in this release The following sections detail what is new in Overview System Configuration (NN ) for Release 4.4. Asset ID configuration You can configure the Asset ID with ACLI commands or EDM. An Asset ID provides inventory information for the switch, stack, or each unit within a stack. Show Software Status The show boot ACLI command or the Boot Image EDM tab can display the currently loaded and operational software status for both agent and diagnostic images AB integration With AB, Link Layer Discovery Protocol (LLDP) integration you can simplify the deployment of Avaya voice solutions with Avaya data products because AB integration supports a set of Avaya-specific TLVs that you can use to provision and report about parameters that support Avaya IP Telephones. When you use the 802.1AB integration TLVs, you achieve a more rapid deployment of voice solutions and you can also view information from the data network about the services the voice solutions use AB integration also works with Avaya Energy Saver to maximize off-peak power savings for network and voice services without impact to service AB customization 802.1AB, Link Layer Discovery Protocol (LLDP) customization expands LLDP capabilities so that you can customize all of the LLDP advertisements and timers. The enhanced flexibility provided by the additional customization makes LLDP suitable for deployments where a variety of vendor equipment or deployment methods exist.

17 Chapter 2: Introduction This guide provides information about configuring and managing basic switching features on the Avaya Ethernet Routing Switch 2500 Series. Unless otherwise indicated, this information applies to Ethernet Routing Switch 2526T Ethernet Routing Switch 2526T-PWR Ethernet Routing Switch 2550T Ethernet Routing Switch 2550T-PWR The term "Ethernet Routing Switch 2500 Series" is used in this document to describe the features common to the switches mentioned above. A switch is referred to by its specific name while describing a feature exclusive to the switch. The Ethernet Routing Switch 2500 Series switches operate in the Stand-alone Mode and Stacking Mode in this product release. A switch can be in Stand-alone Mode or in Stacking Mode, not both. ACLI command modes ACLI provides the following command modes: User EXEC Privileged EXEC Global Configuration Interface Configuration Mode access is determined by access permission levels and password protection. If no password is set, you can enter ACLI in User EXEC mode and use the enable command to move to the next level (Privileged EXEC mode). However, if you have read-only access, you cannot progress beyond User EXEC mode, the default mode. If you have read-write access you can progress from the default mode through all of the available modes. With sufficient permission, you can use the rules in the following table to move between the command modes. Overview System Configuration July

19 Chapter 3: System configuration fundamentals This chapter describes the system configuration fundamentals for the Avaya Ethernet Routing Switch 2500 Series. Stacking functionality delivery The Avaya Ethernet Routing Switch 2500 series switches allow you to stack multiple switches together to create a single virtual switch that can be managed as a single device. Stacking functionality is delivered in two distinctively different ways on Ethernet Routing Switch 2500 series switches: Through stack enabled units with order codes AL2515xxx-E6. The rear ports of stack enabled ERS 2500 switch are factory pre-enabled, configured, and operating in Stacking Mode by default and are ready to stack. These units do not require or use the software licensing mechanism. Through software using a licensing mechanism for stand-alone units with order codes AL2500xxx-E6. Stand-alone ERS 2500 switches require the purchase of a Stacking License Kit for each license to create a license file, which unlocks stacking capability on stand-alone units. Stack enabled switches The stack enabled unit rear ports are configured in Stacking Mode at the factory and are ready for immediate use for connection in a stack configuration. Stacking Mode is the default operating mode that cannot be overridden by a factory default. Stand-alone Mode operation is still available for configuration on the rear-ports of stack enabled units. For information about adding or replacing a new unit, see Avaya Ethernet Routing Switch Fundamentals (NN ). All factory stack pre-enabled units are identifiable through CLI, and EDM with the text Stack Enabled included in the switch description for identification purposes. Overview System Configuration July

20 System configuration fundamentals Stand-alone configuration with license files Stand-alone units are not pre-enabled with stacking capability in the factory and require the use of a software based licensing mechanism to unlock stacking functionality for activation on the rear ports. Stand-alone units use the GenLic engine for decryption of a license file. The license file must contain the switch MAC address to unlock the stacking functionality. Stand-alone units require the purchase of an Ethernet Routing Switch 2500 series Stacking License Kit, of which there are four types available. Each kit contains a License Certificate with a License Authorization Code (LAC) that enables a specific number of stacking licenses for one or multiple ERS 2500 series switches. Each ERS 2500 series switch requires one license file to unlock stacking functionality. A single license file can contain up to 1000 switch MAC addresses for installation on multiple switches. A Stacking License Certificate contains instructions to deposit license entitlements into a license bank, enter switch MAC address(es), create the license file, and then download and copy the license file onto each switch requiring stacking functionality. These instructions are carried out on the Avaya Licensing portal web site at: Important: Once you download a valid license file to an Avaya Ethernet Routing Switch 2500 Series switch, you can configure the operational mode of rear ports to Stacking Mode. Although the rear ports are set to Stacking Mode, a restart of the switch is required to fully enable the stacking operation. For more information about licenses, see Avaya Ethernet Switch 2500 Fundamentals (NN ). Feature licensing This section contains information about feature licenses. Release 4.4 do not support feature licenses. Demonstration license Avaya Ethernet Routing Switch 2500 Series does not require demonstration licenses. 20 Overview System Configuration July 2012 Comments? infodev@avaya.com

21 Autosave feature Autosave feature By default, every 60 seconds the Ethernet Routing Switch checks whether a configuration change has occurred, or if a log message is written to nonvolatile storage. If one of these two events has occurred, the system automatically saves its configuration and the nonvolatile log to flash memory. Also, the system automatically saves the configuration file if a system reset command is invoked by the user. Important: Do not power off the switch within 60 seconds of changing configuration parameters. Doing so causes loss of changes in the configuration parameters. You can enable or disable the autosave feature using the autosave enable and no autosave enable commands. You can use ACLI command copy config nvram to force a manual save of the configuration when the autosave feature is disabled. Domain Name Server (DNS) You can use the Domain Name Server (DNS) client to ping or Telnet to a host server or to a host by name. To use this feature, you must configure at least one DNS. You can also configure a default domain name. If you configure a default domain name, that name is appended to host names that do not contain a dot. The default domain name and addresses are saved in NVRAM. The host names for ping and Telnet cannot be longer than 63 alphanumeric characters, and the default DNS domain name cannot be longer than 255 characters. You can also use the ping command to specify additional ping parameters, including the number of ICMP packets to be sent, the packet size, the interval between packets, and the timeout. You can also set the ping to continuous, or you can set a debug flag to obtain extra debug information. BootP automatic IP configuration and MAC address The Ethernet Routing Switch 2500 Series has a unique 48-bit hardware address, or MAC address, that is printed on a label on the back panel. You can use this MAC address when you Overview System Configuration July

22 System configuration fundamentals configure the network BootP server to recognize the Ethernet Routing Switch 2500 Series BootP requests. A properly configured BootP server lets the switch automatically learn its assigned IP address, subnet mask, IP address of the default router (default gateway), and software image file name. For more information and an example of a BootP configuration file, see Sample BootP configuration file on page 289. Choosing a BootP request mode The BootP Request Mode field lets you choose which method the switch uses to broadcast BootP requests: BootP or Default IP BootP Always BootP Disabled BootP or Last Address Important: Whenever the switch is broadcasting BootP requests, the BootP process eventually times out if a reply is not received. When the process times out, the BootP request mode automatically changes to BootP Disabled mode. To restart the BootP process, change the BootP request mode to any of the three following modes: always default-ip disable last BootP or Default IP The Ethernet Routing Switch 2500 Series operates in the BootP or Default IP mode (the default mode) as follows: After the switch is reset or power cycled, if the switch has a configured IP address other than or the default IP address then the switch uses the configured IP address. If the configured IP address is or the default IP address ( /24) then the switch attempts BootP for 1 minute. If BootP succeeds then the switch uses the IP information provided. 22 Overview System Configuration July 2012 Comments? infodev@avaya.com

23 Choosing a BootP request mode If BootP fails and the configured IP address is the default then the switch uses the default IP address ( /24). If BootP fails and the configured IP address is then the switch retains this address. BootP Always This option lets you manage the switch that is configured with the IP address obtained from the BootP server. The Ethernet Routing Switch 2500 Series operates in the BootP Always mode as follows: The switch continues to broadcast BootP requests, regardless of whether an in-band IP address is set from the console terminal. If the switch receives a BootP reply that contains an in-band IP address, the switch uses this new in-band IP address. If the BootP server is not reachable, you cannot change the in-band IP address until the BootP mode is set to BootP Disabled. However, after a period of a few minutes (appoximately 10 minutes), the switch automatically enters the BootP Disabled mode. You can then configure the IP address with ACLI. If an IP address is not currently in use, these actions take effect immediately. If an IP address is currently in use, these actions take effect only after the switch is reset or power cycled. BootP Disabled This option lets you manage the switch by using the IP address set from the console terminal. The Ethernet Routing Switch 2500 Series operates in the BootP Disabled mode as described in the following steps: The switch does not broadcast BootP requests, regardless of whether an IP address is set from the console terminal. The switch can be managed only by using the in-band switch IP address set from the console terminal. Overview System Configuration July

24 System configuration fundamentals BootP or Last Address This option lets you manage the switch even if a BootP server is not reachable. The Ethernet Routing Switch 2500 Series operates in the BootP or Last Address mode as described in the following steps: When you specify the IP data from the console terminal, the IP address becomes the inband address of the switch. BootP requests are not broadcast. You can manage the switch using this in-band IP address. When you do not specify the in-band IP address from the console terminal, the switch broadcasts BootP requests until it receives a BootP reply containing an in-band IP address. If the switch does not receive a BootP reply that contains an in-band IP address within 10 minutes, the switch uses the last in-band IP address it received from a BootP server. This IP information is displayed in the Last BootP column. If the IP address specified as the in-band IP address is not currently in use, these actions take effect immediately. If an IP address is currently in use, these actions take effect only after the switch is reset or power cycled. Default BootP setting With Release 4.2 (and above) software, the default operational mode for BootP on the switch is BootP or Default IP. The switch requests an IP address from BootP only if one is not already set from the console terminal (or if the IP address is the default IP address: ). Flash memory storage The following sections describe flash memory. Switch software image storage The Ethernet Routing Switch 2500 Series uses flash memory to store the switch software image. The flash memory lets you update the software image with a newer version without changing the switch hardware (see Upgrading software using ACLI on page 143). An in-band connection between the switch and the TFTP load host is required to download the software image. 24 Overview System Configuration July 2012 Comments? infodev@avaya.com

25 Configuration file download and upload Configuration file download and upload The Configuration management feature lets you store and retrieve the configuration parameters of an Ethernet Routing Switch 2500 Series to a TFTP server. This feature supports two different methods for managing system configuration files: Binary configuration file on page 26 ASCII configuration file on page 26 Before you change the switch configuration, you can use the show running-config command to view the current configuration. The command displays only those parameters that differ from the default switch configuration. If you want to view the entire configuration, you can use the verbose qualifier, or you can use the module qualifier to view the configuration for a specific feature. For more information, see show running-config command on page 89. Requirements The following requirements apply to the Configuration file feature: A configuration file obtained from a stack can only be used to configure other stacks that have the same firmware revision and model types as the donor stack. Units in a stack must be arranged in the same order as the donor stack. A configuration file obtained from a stand-alone switch can only be used to configure other stand-alone switches that have the same firmware revision and model type as the donor stand-alone switch. The following table describes configuration file parameter information. Table 2: Parameters not saved to the configuration file In-Band Switch IP Address In-Band Subnet Mask Default Gateway Configuration Image Filename TFTP Server IP Address Terminal settings (speed, width, length) These parameters are not saved Overview System Configuration July

26 System configuration fundamentals Binary configuration file You can store the configuration parameters of a switch to a TFTP server and retrieve the stored parameters to automatically configure a replacement switch. Certain requirements apply when automatically configuring a switch using this feature (see Requirements on page 25). You can set up the file on your TFTP server and set the filename read and write permission to enabled before you can save the configuration parameters. Although most configuration parameters are saved to the configuration file, certain parameters are not saved (see Table 2: Parameters not saved to the configuration file on page 25). ASCII configuration file You can also store the configuration parameters of a switch/stack as an ASCII configuration file and retrieve the stored file to automatically configure a replacement switch/stack. Autotopology You can enable the Optivity* Autotopology* protocol on the Ethernet Routing Switch 2500 Series with ACLI. For more information about Autotopology, go to the Avaya support site: (The product family for Optivity and Autotopology is Data and Internet.) Autotopology is enabled by default. Stack Forced Mode Stack Forced Mode allows one or both units of a two-unit stack to become stand-alone switches if a stack of two units fails. You can manage the units from the broken stack in Stack Forced Mode. If you enable Stack Forced Mode on a stack, you enable Stack Forced Mode on both units in the stack. Stack Forced Mode becomes active only if the stack fails. You can configure Stack Forced Mode through ACLI.

27 Stacking fundamentals Stack Forced Mode applies to a stand-alone switch that is part of a stack of two units. When functioning in this mode, the stand-alone switch keeps the previous stack IP settings (IP address, netmask, and gateway). An administrator can reach the device through an IP connection by Telnet or Enterprise Device Manager while using Stack Forced Mode. If one unit fails, the remaining unit (base or non-base unit) keeps the previous stack IP settings. The remaining unit issues a gratuitous ARP packet when it enters Stack Forced Mode, in order for other devices on the network to update their ARP cache. If the stack connection between the two units fails (a stack cable failure, for example), both stand-alone units retain the IP settings. To detect if the other stack partner is also using the previous stack IP settings, each device issues an ARP request on the IP address. Non-EAP clients connected to the device can still authenticate themselves and maintain connectivity to the network using Stack Forced Mode. Non-EAP clients authenticate by the device with RADIUS, which is based on the stack IP address. In Stack Forced Mode, the device retains the IP settings of the stack of two. The functional unit stays in Stack Forced Mode until either a reboot or it joins a stack. A settlement timer prevents several stack failures that occur at an interval of a few seconds to lead to a device entering Stack Forced Mode after it was part of a stack larger than two units. A device enters Stack Forced Mode if and only if it was part of a stack of two for 30 seconds or longer. Stacking fundamentals This chapter includes information about the stacking features, such as stack capabilities, stacking functionality delivery, stack configuration, and Auto Unit Replacement. Stacking capabilities The Avaya Ethernet Routing Switch 2500 Series switches contain two built-in rear ports that can be used as stacking/cascade ports to enable a stack of up to eight units. A stack can consist of Avaya Ethernet Routing Switch 2526T, Avaya Ethernet Routing Switch 2550T, Avaya Ethernet Routing Switch 2526T-PWR, and Avaya Ethernet Routing Switch 2550T-PWR units. The stack ports on ERS 2500 series switches provide 4Gbps (FDX) stack bandwidth for an aggregate of up to 32Gbps for a stack of eight units. Overview System Configuration July

28 System configuration fundamentals A stack of Ethernet Routing Switch 2500 Series switches can also consist of a mix of stack pre-enabled units as well as non pre-enabled units. The non pre-enabled units in a stack must meet the following requirements before they are added into a stack configuration: Contain a valid license file (a license file contains the switch MAC addresses). Operational mode of rear ports is Stacking Mode. Auto Unit Replacement The Auto Unit Replacement (AUR) feature enables users to replace a unit from a stack while retaining the configuration of the unit. This feature requires the stack power to be on during the unit replacement. The main feature of the AUR is the ability to retain the configuration (CFG) image of a unit in a stack during a unit replacement. The retained CFG image from the old unit is restored to the new unit. Because retained CFG images are kept in the DRAM of the stack, the stack power must be kept on during the procedure. Important: In order for AUR to function properly, the new unit and the existing units in the stack must all be running the same version of software. If that is not the case, it must have at least release 4.2 software, so that image can be updated using AAUR feature. Important: AUR is intended for a stack configuration of two or more units. In a two-unit stack configuration, if a unit fails, the remaining unit becomes a stand-alone switch. AUR loads the configuration of the failed unit in the replacement of ERS 2500 Series unit if the failed unit was a non-base Unit. AUR is not designed for the situation of removing and reinserting the same switch (with the same MAC address). Other information related to this feature: The new unit must be the same hardware configuration as the old, including the same number of ports. If the administrator adds a new unit with a different hardware configuration, the configuration of this unit is used. If the administrator adds a new unit with the same hardware configuration, the previous configuration of the new unit is lost. The previous configuration of the new unit is overwritten with the restored configuration from the stack. This feature can be disabled/enabled at any time with ACLI. The default mode is ENABLE. Customer log messages are provided. 28 Overview System Configuration July 2012 Comments? infodev@avaya.com

29 Stacking fundamentals Important: After starting a stack, use ACLI command show stack auto-unit-replacement from a unit console to find out if that unit is ready for replacement. AUR function The CFG mirror image is a mirror of a CFG image (in FLASH) of a unit in a stack. The mirror image does not reside in the same unit with the CFG image. The unit that contains the CFG image is called the Associated Unit (AU) of the CFG mirror image. The MAC Address of the AU is called the Associated Mac Address (AMA) of the CFG mirror image. An active CFG Mirror Image is a CFG mirror image that has its AU in the stack. An INACTIVE CFG Mirror Image is a CFG mirror image for which the associated AU has been removed from the stack. When a CFG mirror image becomes INACTIVE, the INACTIVE CFG mirror image is copied to another unit. The stack always keeps two copies of an INACTIVE CFG mirror image in the stack in case one unit is removed the other unit can still provide the backup INACTIVE CFG mirror image. CFG mirror image process The CFG mirror image process is triggered by specific events. Power Cycle After a power cycle, all the CFG images in a stack are mirrored. Figure 1: CFG mirror process in stack on page 30 illustrates the CFG mirror images in a three-unit stack after the stack is powered on. Unit 1 is the Based Unit (BU) and all other units are Non-Based Units (NBU). Unit 1 (BU) contains mirror images for unit 2 (CFG 2) and unit 3 (CFG 3). Unit 2 (NBU), is the TEMP-BU. It contains a mirror image of unit 1 (CFG 1), in case the BU (unit 1) is removed from the stack. All three mirror images (CFG 1, CFG 2, and CFG 3) are active. Unit 2 is the Associated Unit of the CFG 2 mirror image. The Mac Address 2 is the Associated Mac Address (AMA) of the CFG 2 mirror image. Overview System Configuration July

30 System configuration fundamentals Figure 1: CFG mirror process in stack Adding a unit In a stack that does not have any INACTIVE CFG mirror images, adding a new unit causes the CFG image of the new unit to be mirrored in the stack. For example, in Figure 2: CFG mirror images in the stack after adding unit 4 on page 31, after adding unit 4 to the stack, the CFG 4 mirror image is created in the BU (unit 1). 30 Overview System Configuration July 2012 Comments? infodev@avaya.com

31 Stacking fundamentals Figure 2: CFG mirror images in the stack after adding unit 4 Removing an NBU When an NBU is removed from a stack, the related CFG mirror image in the stack becomes INACTIVE. The AUR feature ensures that the stack always has two copies of an INACTIVE CFG mirror image. These two copies must not reside in the same unit in the stack. For example, after the removal of unit 4 from the stack shown in Figure 2: CFG mirror images in the stack after adding unit 4 on page 31, the CFG 4 mirror image becomes INACTIVE (see Figure 3: CFG mirror images after removing unit 4 on page 32). Another copy of the INACTIVE CFG 4 mirror image is also created in unit 2. Overview System Configuration July

32 System configuration fundamentals Figure 3: CFG mirror images after removing unit 4 Removing a BU When a BU is removed, the TEMP-BU assumes the role of the BU. Because all the CFG mirror images of the NBUs reside in the removed BU, the TEMP-BU mirrors all the CFG image of the NBUs in the stack. After the removal of the BU from the stack shown in Figure 2: CFG mirror images in the stack after adding unit 4 on page 31, the TEMP-BU (unit 2) has to mirror all the CFG images in the stack (see Figure 4: CFG mirror images in the stack after removing the BU (unit 1) on page 33). The feature also ensures that the stack always has two copies of an INACTIVE CFG mirror image. 32 Overview System Configuration July 2012 Comments? infodev@avaya.com

33 Stacking fundamentals Figure 4: CFG mirror images in the stack after removing the BU (unit 1) As shown in Figure 4: CFG mirror images in the stack after removing the BU (unit 1) on page 33: Unit 2 becomes the TEMP-BU. The CFG 1 mirror image (residing in unit 2) becomes INACTIVE. A second copy of the INACTIVE CFG 1 mirror image is created in unit 3. The TEMP-BU (unit 2) contains all CFG mirror images of the stack's NBUs. The CFG 2 mirror image is created in unit 3. Unit 3 becomes the next TEMP-BU in case the current TEMP-BU is removed. Restoring a CFG image Restoring a CFG image is a process that overwrites the CFG image of a new unit in a stack with an INACTIVE mirror image stored in the stack. Overview System Configuration July

34 System configuration fundamentals Important: Restore a CFG image to a new unit happens only if the following conditions are met. The AUR feature is enabled. There is at least one INACTIVE CFG mirror image in the stack. The MAC Address of the new unit is different from all the AMA of the INACTIVE CFG mirror images in the stack. The image restore process consists of the following steps: 1. Adding a new unit to a stack 2. The INACTIVE CFG mirror image in the stack is sent to the new unit. The INACTIVE CFG mirror image becomes ACTIVE. 3. The new unit saves the received CFG image to its flash. 4. The new unit resets itself. For example, if a unit 5 (MAC Address 5) is added to the stack shown in Figure 4: CFG mirror images in the stack after removing the BU (unit 1) on page 33, the following occurs (see Figure 5: CFG mirror images in the stack after adding unit 5 on page 35): The INACTIVE CFG 1 mirror image is copied to the CFG 5 image. Unit 5 now has the configuration of unit 1 that is no longer in the stack. The INACTIVE CFG 1 mirror image in unit 2 becomes ACTIVE. The INACTIVE CFG 1 mirror image in unit 3 is removed. The MAC Address 5 of the unit 5 becomes the new AMA of the CFG 1 mirror image. 34 Overview System Configuration July 2012 Comments? infodev@avaya.com

35 Stacking fundamentals Figure 5: CFG mirror images in the stack after adding unit 5 Synchronizing the CFG mirror images with CFG images A CFG mirror image is updated whenever a CFG flash synchronization occurs in the AU. Agent Auto Unit Replacement (AAUR) Use the enhancement to the Auto Unit Replacement functionality, known as the Agent Auto Unit Replacement (AAUR), to ensure that all units in a stack have the same software image by inspecting units joining a stack and downloading the stack software image to any unit that has a dissimilar image. AAUR is enabled by default. Agent Auto Unit Replacement functions in the following manner: 1. When a stand-alone switch joins an AAUR-enabled stack, the switch software image is inspected. 2. If the switch software image differs from the stack software image, the AAUR functionality downloads the stack software image to the joining unit. 3. The joining unit is then reset and becomes a member of the stack upon a restart. Overview System Configuration July

36 System configuration fundamentals Important: In order for AAUR to function properly, the new unit must be running release 4.2 software (or later). Diagnostics Auto Unit Replacement (DAUR) In Release 4.4 and up, DAUR is part of the Auto Unit Replacement process, which includes Agent Auto Unit Replacement (AUR). When you enable or disable AAUR, you also enable or disable DAUR concurrently. There are no commands to separately enable or disable DAUR. The default configuration for AAUR is enabled, so DAUR is also enabled by default. After you enable AAUR, DAUR can update the diagnostic image of the non-base unit with the diagnostic image saved in the base unit of a stack. DAUR updates the diagnostic image on inserted units in the same way that AAUR performs this function for agent code. The DAUR process works in conjunction with AAUR. When you insert a new unit into an existing stack, the system checks the diagnostics image against other units and upgrades the diagnostics image of the new unit if necessary. Release 4.4 and up support DAUR. Previous software releases do not support DAUR. For example, you cannot insert a switch that uses software release 4.0 into an existing stack. You must meet the following conditions before you connect the stack ports of a replacement unit into a stack. The replacement unit must have: a minimum of software release 4.1 loaded a Stacking License file loaded or be a stack-enabled switch the rear ports configured and operating in Stacking Mode (the default mode for a stackenabled switch) What happens when you add or replace a stack non-base unit When you enable AAUR on a stack and then add another unit with a different software image, this unit does not join the stack immediately. The unit remains in stand-alone mode. The new unit sends an AAUR request to the up stream port. If the unit does not receive an answer, it sends a request to the downstream port. After the image transfers successfully, the switch reboots. The log file displays the following messages when DAUR completes successfully: I 2 00:02:01:20 18 DAUR - Info: Receive request for diagnostic image, start transfer I 2 00:02:01:22 19 DAUR - Info: Diagnostic transfer finished 36 Overview System Configuration July 2012 Comments? infodev@avaya.com

37 Stacking fundamentals If you add a non-base unit (the base unit select switch is set to off) to an existing operational stack, the non-base unit receives the diagnostic image from the base unit. When the switch finishes the diagnostic image version update, the switch performs an AAUR check. Results of the AAUR check: If the new unit has the same agent image as the stack, the unit reboots If the new unit has a different agent image, the switch performs an AAUR operation NOTE: The new unit added to a stack must have an agent image with software release 4.4 or higher or AAUR and DAUR cannot upgrade the new unit. The following stacking basics apply: If there is more than one unit in a stack with the base seletion switch set to base, the unit discovery process fails If no units in a stack have the base selection switch set to base, the unit discovery process fails. After a stack of more than 2 switches forms, if the base unit stops communicating the system selects a non-base unit as the temporary base unit (TBU). The unit select switch on the TBU is not set to base but the TBU retains its status as base unit, even if the former base unit reboots, until you reboot the stack. The former base unit acts as a non base unit until you reboot the stack. What happens when you replace a stack base unit In a stack of more than 2 switches, if the base unit fails and the system selects a non-base unit as TBU, when you replace the base unit you must set its base unit selector switch to on. Otherwise, after you power the TBU off, there is no designated base unit and the stack cannot form. The TBU remains as base unit only until it is powered off. After you replace the base unit, with its base unit selector switch set to on, and reboot the stack, the DAUR/AAUR processes start and all non-base units are checked against the images on the base unit. The following table shows expected AAUR and DAUR behavior for different situations. Table 3: Examples of AAUR and DAUR behavior in different situations Stack master image and diagnostic version Software 5.0/5.1 Diagnostic 5.0/5.1 Software 5.0/5.1 Diagnostic 5.2 Slave image diagnostic version Software 5.0/5.1 Diagnostic 5.0/5.1 Software 5.0/5.1 Diagnostic 5.2 Software 5.2 Diagnostic 5.0/5.1 Expected behavior Same image. Unit joins stack. Same image. Unit joins stack. AAUR performed. AAUR downgrades the unit image and reboots the unit. Overview System Configuration July

38 System configuration fundamentals Stack master image and diagnostic version Software 5.2_SSH/non SSH Diagnostic 5.2 Slave image diagnostic version Software 5.2 Diagnostic 5.2 Software 5.0/5.1 Diagnostic 5.0/5.1 Software 5.0/5.1 Diagnostic 5.2 Software 5.2_non SSH/SSH Diagnostic 5.1 Software 5.2_non SSH/SSH Diagnostic 5.2 Expected behavior The unit joins the stack after the reboot. No DAUR performed as DAUR is unavailable on 5.0/5.1 AAUR performed. AAUR upgrades the unit image then reboots the stack. DAUR upgrades the diagnostic image then reboots the unit. The unit joins the stack after the reboot. AAUR performed. AAUR upgrades the unit image then reboots the unit. Since the diagnostic images are the same, the unit joins the stack. Since the diagnostic and agent images are the different, DAUR upgrades the diagnostic image, and then AAUR transfers the agent. AAUR and DAUR reboot the unit. The unit joins the stack after the reboot. AAUR performs the agent image transfer and reboots the unit. The unit joins the stack after the reboot. With version 4.4, when stack forced-mode is enabled and the base unit remains, Agent Auto Unit Replacement and Diagnostic Auto Unit Replacement are working as explained on the preceding table. Large image file If the agent image size exceeds 6 Mb, the switch cannot perform the DAUR and the switch sends an error message to the base unit. You must perform a manual image upgrade or downgrade in this situation for both the diagnostic and agent images. IPv6 Management This section provides information about the IPv6 management feature. 38 Overview System Configuration July 2012 Comments? infodev@avaya.com

39 IPv6 Management The IPv6 header The IPv6 header contains the following fields: a 4-bit Internet Protocol version number, with a value of 6 an 8-bit traffic class field, similar to Type of Service in IPv4 a 20-bit flow label that identifies traffic flow for additional Quality of Service (QoS) a 16-bit unsigned integer, the length of the IPv6 payload an 8-bit next header selector that identifies the next header an 8-bit hop limit unsigned integer that decrements by 1 each time a node forwards the packet (nodes discard packets with hop limit values of 0) a 128-bit source address a 128-bit destination address IPv6 addresses IPv6 addresses are 128 bits in length. The address identifies a single interface or multiple interfaces. IPv4 addresses, in comparison, are 32 bits in length. The increased number of possible addresses in IPv6 solves the inevitable IP address exhaustion inherent to IPv4. The IPv6 address contains two parts: an address prefix and an IPv6 interface ID. The first 3 bits indicate the type of address that follows. Beginning with software release 4.3, the Ethernet Routing Switch 2500 does not support stateless or stateful address configuration. The device does not try to obtain ipv6 parameters from a router and it does not query an IPv6 DHCP server, if it does not have an IPv6 address configured. The IPv6 global address of the 2500 series switch must be entered manually. The link-local IPv6 address is generated automatically, based on the MAC address of the device, once the IPv6 interface is attached to the management VLAN. Figure 6: IPv6 address format on page 39 shows the IPv6 address format. Figure 6: IPv6 address format An example of a unicast IPv6 address is 1080:0:0:0:8:8000:200C:417A Overview System Configuration July

40 System configuration fundamentals Interface ID The interface ID is a unique number that identifies an IPv6 node (a host or a router). For stateless autoconfiguration, the ID is 64 bits in length. In IPv6 stateless autoconfiguration, the interface ID is derived by a formula that uses the link layer 48-bit MAC address. (In most cases, the interface ID is a 64-bit interface ID that contains the 48-bit MAC address.) The IPv6 interface ID is as unique as the MAC address. If you manually configure interface IDs or MAC addresses (or both), no relationship between the MAC address and the interface ID is necessary. A manually configured interface ID can be longer or shorter than 64 bits. Address formats The format for representing an IPv6 address isn:n:n:n:n:n:n:nn is the hexadecimal representation of 16 bits in the address. An example is as follows:ff01:0:0:0:0:0:0:43 Each nonzero field must contain at least one numeral. Within a hexadecimal field, however, leading zeros are not required. Certain classes of IPv6 addresses commonly include multiple contiguous fields containing hexadecimal 0. The following sample address includes six contiguous fields containing zeroes with a double colon (::):FF01::43 You can use a double colon to compress the leading zero fields in a hexadecimal address. A double colon can appear once in an address. An IPv4-compatible address combines hexadecimal and decimal values as follows:x:x:x:x:x:x:d.d.d.d x:x:x:x:x:x is a hexadecimal representation of the six high-order 16- bit pieces of the address, and d.d.d.d is a decimal representation of the four 8-bit pieces of the address. For example:0:0:0:0:0:0: or :: IPv6 extension headers IPv6 extension headers describe processing options. Each extension header contains a separate category of options. A packet can include zero or more extension headers. For more information, see Figure 7: IPv6 header and extension headers on page Overview System Configuration July 2012 Comments? infodev@avaya.com

41 IPv6 Management Figure 7: IPv6 header and extension headers IPv6 examines the destination address in the main header of each packet it receives; this examination determines whether the router is the packet destination or an intermediate node in the packet data path. If the router is the destination of the packet, IPv6 examines the header extensions that contain options for destination processing. If the router is an intermediate node, IPv6 examines the header extensions that contain forwarding options. By examining only the extension headers that apply to the operations it performs, IPv6 reduces the amount of time and processing resources required to process a packet. IPv6 defines the following extension headers: The hop-by-hop extension header contains optional information that all intermediate IPv6 routers examine between the source and the destination. The end-to-end extension header contains optional information for the destination node. The source routing extension header contains a list of one or more intermediate nodes that define a path for the packet to follow through the network, to its destination. The packet source creates this list. This function is similar to the IPv4 source routing options. An IPv6 source uses the fragment header to send a packet larger than can fit in the path maximum transmission unit (MTU) to a destination. To send a packet that is too large to fit in the MTU of the path to a destination, a source node can divide the packet into fragments and send each fragment as a separate packet, to be reassembled at the receiver. The authentication extension header and the security encapsulation extension header, used singly or jointly, provide security services for IPv6 datagrams. Comparison of IPv4 and IPv6 The following table compares key differences between IPv4 and IPv6. Table 4: IPv4 and IPv6 differences Feature IPv4 IPv6 Address length 32 bits 128 bits IPsec support (See Note 1) Optional Required QoS support Limited Improved Overview System Configuration July

ICMPv6 Internet Control Message Protocol (ICMP) version 6 maintains and improves upon features from ICMP for IPv4. ICMPv6 reports the delivery of forwarding errors, such as destination unreachable, packet too big, time exceeded, and parameter problem. ICMPv6 also delivers information messages such as echo request and echo reply. Important: ICMPv6 plays an important role in IPv6 features such as neighbor discovery, Multicast Listener Discovery, and path MTU discovery. Neighbor discovery IPv6 nodes (routers and hosts) on the same link use neighbor discovery (ND) to discover link layer addresses and to obtain and advertise various network parameters and reachability information. ND combines the services provided for IPv4 with the Address Resolution Protocol (ARP) and router discovery. Neighbor discovery replaces ARP in IPv6. Hosts use ND to discover the routers in the network that you can use as the default routers, and to determine the link layer address of their neighbors attached on their local links. Routers also use ND to discover their neighbors and their link layer information. Neighbor discovery 42 Overview System Configuration July 2012 Comments? infodev@avaya.com

43 IPv6 Management also updates the neighbor database with valid entries, invalid entries, and entries migrated to different locations. Neighbor discovery protocol provides you with the following: Address and prefix discovery: hosts determine the set of addresses that are on-link for the given link. Nodes determine which addresses or prefixes are locally reachable or remote with address and prefix discovery. Router discovery: hosts discover neighboring routers with router discovery. Hosts establish neighbors as default packet-forwarding routers. Parameter discovery: host and routers discover link parameters such as the link MTU or the hop limit value placed in outgoing packets. Address autoconfiguration: nodes configure an address for an interface with address autoconfiguration. Duplicate address detection: hosts and nodes determine if an address is assigned to another router or a host. Address resolution: hosts determine link layer addresses (MAC for Ethernet) of the local neighbors (attached on the local network), provided the IP address is known. Next-hop determination: hosts determine how to forward local or remote traffic with nexthop determination. The next hop can be a local or remote router. Neighbor unreachability detection: hosts determine if the neighbor is unreachable, and address resolution must be performed again to update the database. For neighbors you use as routers, hosts attempt to forward traffic through alternate default routers. Redirect: routers inform the host of more efficient routes with redirect messages. Neighbor discovery uses three components: host-router discovery host-host communication component redirect For more information, see Figure 8: Neighbor discovery components on page 43 for the ND components. Figure 8: Neighbor discovery components Overview System Configuration July

44 System configuration fundamentals ND messages The following table shows new ICMPv6 message types. Table 5: IPv4 and IPv6 neighbor discovery comparison IPv4 neighbor function IPv6 neighbor function ARP Request message Neighbor solicitation message A node sends this message to determine the link-layer address of a neighbor or to verify that a neighbor is still reachable through a cached link-layer address. You can also use neighbor solicitations for duplicate address detection. ARP Reply message Neighbor advertisement A node sends this message either in response to a received neighbor solicitation message or to communicate a link layer address change. ARP cache Neighbor cache The neighbor cache contains information about neighbor types on the network. Gratuitous ARP Duplicate address detection A host or node sends a request with its own IP address to determine if another router or host uses the same address. The source receives a reply from the duplicate device. Both hosts and routers use this function. Router solicitation message (optional) Router advertisement message (optional) Router solicitation (required) Router advertisement (required) The host sends this message upon detecting a change in a network interface operational state. The message requests that routers generate router advertisement immediately rather than at the scheduled time. Routers send this message to advertise their presence together with various links and Internet parameters 44 Overview System Configuration July 2012 Comments? infodev@avaya.com

45 IPv6 Management IPv4 neighbor function IPv6 neighbor function either periodically or in response to a router solicitation message. Router advertisements contain prefixes that you use for onlink determination or address configuration, and a suggested hop limit value. Redirect message Redirect message Routers send this message to inform hosts of a better first hop for a destination. Neighbor discovery cache The neighbor discovery cache lists information about neighbors in your network. The neighbor discovery cache can contain the following types of neighbors: static: a configured neighbor local: a device on the local system dynamic: a discovered neighbor The following table describes neighbor cache states. Table 6: Neighbor cache states Incomplete Reachable Stale Delay State A node sends a neighbor solicitation message to a multicast device. The multicast device sends no neighbor advertisement message in response. You receive positive confirmation within the last reachable time period. A node receives no positive confirmation from the neighbor in the last reachable time period. A time period longer than the reachable time period passes since the node received the last positive confirmation, and a packet was sent within the last DELAY_FIRST_PROBE_TIME period. If no reachability confirmation is received within DELAY_FIRST_PROBE_TIME period of entering the DELAY state, neighbor Overview System Configuration July

46 System configuration fundamentals Probe State solicitation is sent and the state is changed to PROBE. Reachability confirmation is sought from the device every retransmit timer period. The following events involve Layer 2 and Layer 3 interaction when processing and affect the neighbor cache: flushing the Virtual Local Area Network (VLAN) media access control (MAC) removing a VLAN performing an action on all VLANs removing a port from a VLAN removing a port from a spanning tree group (STG) removing a multilink trunk group from a VLAN removing an Multi-Link Trunking port from a VLAN removing an Multi-Link Trunking port from an STG performing an action that disables a VLAN, such as removing all ports from a VLAN disabling a tagged port that is a member of multiple routable VLANs Router discovery IPv6 nodes discover routers on the local link with router discovery. The IPv6 router discovery process uses the following messages: router advertisement router solicitation Router advertisement Configured interfaces on an IPv6 router send out router-advertisement messages. Routeradvertisements are also sent in response to router-solicitation messages from IPv6 nodes on the link. Router solicitation An IPv6 host without a configured unicast address sends router solicitation Messages. Beginning with software release 4.3, the Ethernet Routing Switch 2500 does not support 46 Overview System Configuration July 2012 Comments? infodev@avaya.com

47 Ethernet port management features stateless automatic configuration. Therefore no router solicitation messages are sent by the switch. Path MTU discovery IPv6 routers do not fragment packets. The source node sends a packet equal in size to the maximum transmission unit (MTU) of the link layer. The packet travels through the network to the source. If the packet encounters a link to a smaller MTU, the router sends the source node an ICMP error message containing the MTU size of the next link. The source IPv6 node then resends a packet equal to the size of the MTU included in the ICMP message. The default MTU value for a regular interface is Ethernet port management features Autosensing and autonegotiation The Ethernet Routing Switch 2500 Series is an autosensing and autonegotiating device: The term autosense refers to the ability of a port to sense the speed of an attached device. The term autonegotiation refers to a standardized protocol (IEEE 802.3u) that exists between two IEEE 802.3u-capable devices. Autonegotiation lets the switch select the best of speed and duplex modes. Autosensing is used when the attached device is not capable of autonegotiation or is using a form of autonegotiation that is not compatible with the IEEE 802.3u standard. In this case, because it is not possible to sense the duplex mode of the attached device, the Ethernet Routing Switch 2500 Series reverts to half-duplex mode. When autonegotiation-capable devices are attached to the Ethernet Routing Switch 2500 Series, the ports negotiate down from 100 Mb/s speed and full-duplex mode until the attached device acknowledges a supported speed and duplex mode. Overview System Configuration July

48 System configuration fundamentals Custom Autonegotiation Advertisements Custom Autonegotiation Advertisements (CANA) lets you customize the capabilities that you advertise. For example, if a port is capable of 10/100/1000 full duplex operation, the port can be configured to only advertise 10 half-duplex capabilities. CANA lets you control the capabilities that are advertised by the Ethernet switches as part of the autonegotiation process. In the current software releases, autonegotiation can either be enabled or disabled. When autonegotiation is disabled, the hardware is configured for a single (fixed) speed and duplex value. When autonegotiation is enabled, the advertisement made by the product is a constant value based upon all speed and duplex modes supported by the hardware. When autonegotiating, the switch selects the highest common operating mode supported between the switch and its link partner. In certain situations, it is useful to autonegotiate a specific speed and duplex value. In these situations, the switch can allow for attachment at an operating mode other than its highest supported value. For example, if the switch advertises only a 100 Mbps full-duplex capability on a specific link, the link goes active only if the neighboring device is also capable of autonegotiating a 100 Mbps full-duplex capability. This prevents mismatched speed and duplex modes if customers disable autonegotiation on the neighboring device. Important: The CANA feature is available only for built-in 10/100 Ethernet ports and combo ports (not available for rear ports). You can only enable CANA through ACLI. High speed flow control The high speed flow control feature lets you control traffic and avoid congestion on the gigabit full-duplex link. If the receive port buffer becomes full, the Ethernet Routing Switch 2500 Series issues a flow-control signal to the device at the other end of the link to suspend transmission. When the receive buffer is no longer full, the switch issues a signal to resume the transmission. You can choose Symmetric or Asymmetric flow control mode. High speed flow control cannot be configured unless you set Autonegotiation to Disabled on the port and the speed/duplex is at 1000/full. Two high speed flow control modes are available: 48 Overview System Configuration July 2012 Comments? infodev@avaya.com

49 Ethernet port management features Symmetric mode This mode lets both GBIC port and its link partner to send flow control pause frames to each other. When a pause frame is received (by either the GBIC port or its link partner), the port suspends transmission of frames for a number of slot times specified in the control frame or until a pauserelease control frame is received. Both devices on the link must support this mode when it is selected. Asymmetric mode This mode lets the link partner send flow control pause frames to the GBIC port. When a pause frame is received, the receiving port suspends transmission of frames for a number of slot times specified in the control frame or until a pause-release control frame is received. In this mode, the GBIC port is disabled from transmitting pause frames to its link partner. Use this mode when the GBIC port is connected to a buffered repeater device. You can choose a high speed flow control mode with ACLI commands. For more information about the commands see Enabling flow control on page 151. Rate Limiting Configuration The Rate Limiting feature lets you configure the threshold limits for broadcast and multicast packets ingressing on a port for a given time interval. The Ethernet Routing Switch 2500 Series drops packets received above the threshold value if the traffic ingressing on the port exceeds the threshold. The hardware restrictions on this platform do not allow you to determine if the traffic from a port is the cause of excess broadcast or multicast traffic. Consequently you cannot perform port specific actions such as disabling a port. You can generate a trap to detect the excess traffic or you can configure the switch to store a message in the system log when the traffic on the port exceeds the threshold value. This message in the system log conveys that some traffic to the switch is dropped. When the volume of either packet type is high, placing severe strain on the network (often referred to as a "storm"), you can set the forwarding rate of those packet types to not exceed a specified percentage of the total available bandwidth. The pps (Packets Per Second) value you set is a small amount of the maximum value of pps for the maximum available bandwidth that is pps. Important: All Rate Limiting configuration settings are applied across the entire unit. You cannot set some ports in the unit to limit broadcast traffic with a value of X pps and some other ports in the same to limit multicast traffic with a value of Y pps.

50 System configuration fundamentals Network devices and the Power over Ethernet cable (PoE) The Ethernet Routing Switch 2550T-PWR and 2526T-PWR provide IEEE 802.3af-compliant power over half of the front-panel RJ-45 ports, located on the left-hand side of the front panel. The switch provides power discovery, power management, and statistics on power use on each port and each switch basis. You can use the Ethernet Routing Switch 2500 Series to provide power to network appliances, such as IP telephones, wireless access points, and video devices. The Ethernet Routing Switch 2526T-PWR and 2550T-PWR provide Power over Ethernet for 12 and 24 ports with respectively. The switches only support PoE on the lower-numbered ports (identified by a red border). The switches provide a maximum of 168 Watts of power to PoE ports. Adequate power is available to supply, on average, 7 Watts for each port on the 2550T- PWR, and 14 Watts for each port on the 2526T-PWR. A maximum of 15.4 Watts is available on any port for any given device. The Ethernet Routing Switch 2550T-PWR and 2526T-PWR supply data terminal equipment (DTE) power only on signal pins. By default, power is allocated based on real time measurements. If the total Ethernet power budget for the switch is exceeded, the switch sheds load by shutting down power to ports. Configure the Power over Ethernet (PoE) parameters on the PoE ports with Avaya Command Line Interface (ACLI) or Device Manager. Simple Network Time Protocol (SNTP) The Simple Network Time Protocol (SNTP) feature synchronizes the Universal Coordinated Time (UTC) to an accuracy within 1 second. This feature adheres to the IEEE RFC 2030 (MIB is the s5agent). With this feature, the system can obtain the time from any RFC 2030-compliant NTP/SNTP server. The system retries connecting with the NTP server a maximum of 3 times, with 5 minutes between each retry. If the connection fails after the 3 attempts, the system waits for the next synchronization time (the default is 24 hours) and begins the process again. Using SNTP SNTP synchronizes the Universal Coordinated Time (UTC) to an accuracy within 1 second. This feature adheres to the IEEE RFC 2030 (MIB is the s5agent). With this feature, the system can obtain the time from any RFC 2030-compliant NTP/SNTP server. 50 Overview System Configuration July 2012 Comments? infodev@avaya.com

51 Small Form Factor Pluggable (SFP) Gigabit Interface Converters (GBIC) The system attempts to connect to the NTP server at least three times, with five minutes duration between each retry. If the connection fails after three attempts, the system waits for the next synchronization time (the default is 24 hours) and begins the process again. The SNTP provides a real-time timestamp for the software, shown as Greenwich Mean Time (GMT). If the SNTP is enabled (the default value is disabled), the system synchronizes with the configured NTP server at startup and at user-configurable periods thereafter (the default sync interval is 24 hours). The first synchronization is not performed until network connectivity is established. The SNTP supports primary and secondary NTP servers. The system tries the secondary NTP server only if the primary NTP server is unresponsive. Small Form Factor Pluggable (SFP) Gigabit Interface Converters (GBIC) Gigabit Interface Converter Small Form Factor Pluggable (SFP) Gigabit Interface Converters (GBIC) are hot-swappable input and output tranceivers designed for use with Avaya products to allow Gigabit Ethernet ports to link with fiber optic networks. SFP GBIC support on the Ethernet Routing Switch 2500 Series The Ethernet Routing Switch 2500 Series supports the following SFPs: 1000Base-SX SFP, 1000Base-SX DDI SFP 1000Base-LX SFP, 1000Base-LX DDI SFP 1000Base-BX SFP (10km) 1000Base-BX DDI SFP (40km) 1000Base-XD SFP (40km) 1000Base-ZX SFP (70km) 1000Base-EX SFP (120km) 1000Base-CWDM SFPs (40km & 70km), Overview System Configuration July

Asset ID configuration An Asset ID provides inventory information for the switch, stack, or each unit within a stack. An Asset ID consists of an alphanumeric string of up to 32 characters in length for the switch or stack. You can configure the Asset ID to record your company specific asset tracking information, such as an asset tag affixed to the switch. You can configure the Asset ID with ACLI commands, or with EDM. Show software status (Agent and diagnostic software status display) You can display the currently loaded and operational switch or stack software status for both agent and diagnostic loads. You can use the show boot ACLI command and variables to display the agent or diagnostic load status individually, or combined. The Boot Image EDM tab displays agent and diagnostic load status information together. 52 Overview System Configuration July 2012 Comments? infodev@avaya.com

53 Chapter 4: Link Layer Discovery Protocol fundamentals Release 4.2 or later supports the Link Layer Discovery Protocol (LLDP) (IEEE 802.1AB), which lets stations connected to a LAN to advertise their capabilities to each other, enabling the discovery of physical topology information for network management. LLDP-compatible stations can consist of any interconnection device including PCs, IP Phones, switches, and routers. Each LLDP station stores LLDP information in a standard Management Information Base (MIB), making it possible for the information to be accessed by a network management system (NMS) or application. Each LLDP station: advertises connectivity and management information about the local station to adjacent stations on the same 802 LAN (802.3 Ethernet with Ethernet Routing Switch 2500) receives network management information from adjacent stations on the same LAN Important: LLDP works in stack mode. LLDP makes it possible to discover certain configuration inconsistencies or malfunctions that can result in impaired communications at higher layers. For example, it can be used to discover duplex mismatches between an IP Phone and the connected switch. LLDP is compatible with IETF PROTO MIB (IETF RFC 2922). Figure 9: How LLDP works on page 54 shows an example of how LLDP works in a network. Overview System Configuration July

54 Link Layer Discovery Protocol fundamentals Figure 9: How LLDP works 1. The Ethernet Routing Switch and router advertise chassis or port IDs and system descriptions to each other. 2. The devices store the information about each other in local MIB databases, accessible using SNMP. 3. A network management system retrieves the data stored by each device and builds a network topology map. LLDP operational modes LLDP is a one-way protocol. An LLDP agent can transmit information about the capabilities and current status of the system associated with its MAC service access point (MSAP) identifier. The LLDP agent can also receive information about the capabilities and current status of the system associated with a remote MSAP identifier. However, LLDP agents cannot solicit information from each other. You can set the local LLDP agent to transmit only, receive only, or to both transmit and receive LLDP information. You can configure the state for LLDP reception and transmission using SNMP or ACLI commands. 54 Overview System Configuration July 2012 Comments? infodev@avaya.com

55 Connectivity and management information Connectivity and management information The information fields in each LLDP frame are in a Link Layer Discovery Protocol Data Unit (LLDPDU) as a sequence of short, variable length, information elements known as type, length, value (TLV). Each LLDPDU includes the following four mandatory TLVs: chassis ID TLV port ID TLV Time to Live TLV End Of LLDPDU TLV The chassis ID and the port ID values are concatenated to form a logical MSAP identifier that is used by the recipient to identify the sending LLDP agent and port. A non-zero value in the Time to Live (TTL) field of the TTL TLV indicates to the receiving LLDP agent how long the LLDPDU information from the MSAP identifier remains valid. All LLDPDU information is automatically discarded by the receiving LLDP agent if the sender fails to update it in a timely manner. A zero value in TTL field of Time To Live TLV tells the receiving LLDP agent to discard the information associated with the LLDPDU MSAP identifier. Beginning with Release 4.1, in addition to the four mandatory TLVs, the switch supports the basic management TLV set. You can specify which of these optional TLVs to include in the transmitted LLDPDUs for each port. Basic management TLV set The basic management TLV set contains the following TLVs: Port Description TLV System Name TLV System Description TLV System Capabilities TLV (indicates both the system supported capabilities and enabled capabilities, such as end station, bridge, or router) Management Address TLV Beginning with Release 4.4 the switch supports IPv4 and IPv6 management addresses and the transmission of all TLVs from the basic management TLV set is enabled by default. Overview System Configuration July

56 Link Layer Discovery Protocol fundamentals Organizationally-specific TLVs for MED devices The optional organizationally-specific TLVs for use by Media Endpoint Devices (MED) and MED network connectivity devices are: Capabilities TLV enables a network element to advertise the LLDP-MED TLVs it is capable of supporting. Network Policy Discovery TLV is a fixed length TLV that enables both network connectivity devices and endpoints to advertise VLAN type, VLAN identifier (VID), and Layer 2 and Layer 3 priorities associated with a specific set of applications on a port. In addition, an LLDP-MED endpoint advertises this TLV for supported application types to enable the discovery of specific policy information and the diagnosis of network policy configuration mismatch issues. Location Identification TLV allows network connectivity devices to advertise the appropriate location identifier information for an endpoint to use in the context of locationbased applications. The Location Identification Discovery extension enables the advertisement of location identifier information to Communication Endpoint Devices (Class III), based on the configuration of the Network Connectivity Device to which it is connected. This is expected to be related to wiremap or similar network topology data, such that the configuration of the Network Connectivity Device can uniquely identify the physical location of the connected MED Endpoint, and hence the correct location identifier information for it to use. Extended Power-via-MDI TLV enables advanced power management between an LLDP- MED endpoint and network connectivity devices. The Extended Power-via-MDI TLV enables the advertisement of fine grained power requirement details, endpoint power priority, and power status for both endpoint and network connectivity devices. Inventory TLVs are important in managed Voice over Internet Protocol (VoIP) networks. Administrative tasks in these networks are made easier by access to inventory information about VoIP entities. The LLDP Inventory TLVs consist of the following: - LLDP-MED Hardware Revision TLV allows the device to advertise its hardware revision. - LLDP-MED Firmware Revision TLV allows the device to advertise its firmware revision. - LLDP-MED Software Revision TLV allows the device to advertise its software revision. - LLDP-MED Serial Number TLV allows the device to advertise its serial number. - LLDP-MED Manufacturer Name TLV allows the device to advertise the name of its manufacturer. - LLDP-MED Model Name TLV allows the device to advertise its model name. - LLDP-MED Asset ID TLV allows the device to advertise its asset ID. 56 Overview System Configuration July 2012 Comments? infodev@avaya.com

57 802.1AB integration Transmitting LLDPDUs When a transmit cycle is initiated, the LLDP manager extracts the managed objects from the LLDP local system MIB and formats this information into TLVs. TLVs are inserted into the LLDPDU. LLDPDU are regularly transmitted at a user-configurable transmit interval (tx-interval) or when variables in the LLPDU are modified on the local system (such as system name or management address). Tx-delay is the minimum delay between successive LLDP frame transmissions. TLV system MIBs The LLDP local system MIB stores the information for constructing the various TLVs to be sent. The LLDP remote systems MIB stores the information received from remote LLDP agents. LLDPDU and TLV error handling LLDPDUs and TLVs that contain detectable errors are discarded. TLVs that are not recognized, but that also contain no basic format errors, are assumed to be validated and are stored for possible later retrieval by network management. Configuring LLDP with ACLI See System configuration using ACLI on page 61 for information about configuring LLDP with ACLI AB integration 802.1AB integration provides a set of LLDP TLVs for Avaya IP telephone support. You can select which Avaya IP phone support TLVs can be transmitted from individual switch ports by enabling or disabling TLV transmit flags for the port. The TLV transmit flags and TLV configuration operate independently of each other. Therefore, you must enable the transmit flag on a switch port for a specific TLV, before the port can transmit that TLV to an Avaya IP phone. A switch port does not transmit Avaya IP phone support TLVs unless the port detects a connected Avaya IP phone. Overview System Configuration July

58 Link Layer Discovery Protocol fundamentals PoE conservation level request TLV With the PoE conservation level request TLV, you can configure the switch to request that an Avaya IP phone, connected to a switch port, operate at a specific power conservation level. The requested conservation level value for the switch can range from 0 to 255, but the Avaya IP Phone supports only 243 levels. If you request a power conservation level higher than 243, the Avaya IP phone reverts to its maximum power conservation level. If you select a value of 0 for the PoE conservation level request, the switch does not request a power conservation level for an Avaya IP phone. If you set the PoE conservation level request TLV on a port and you enable energy-saver for the port, the TLV value is temporarily modified for maximum power savings by the switch. When you disable energy-saver for the port, the switch automatically restores the power conservation level request TLV to the previous value. If you set the PoE conservation level on a port while AES is active on the port and the maximum PoE Conservation level for the switch is 255, the switch replaces the PoE conservation level stored for AES restoration with the new value you set for the port. By default, the transmission of PoE conservation level request TLV is enabled on all PoE capable switch ports. You can only configure the PoE conservation level request TLV on switches that support PoE. PoE conservation level support TLV With the PoE conservation level support TLV, an Avaya IP phone transmits information about current power save level, typical power consumption, maximum power consumption, and power conservation level of the IP phone, to a switch port. Call server TLV With the call server TLV, you can configure the switch to advertise the IP addresses of a maximum of 8 call servers to connected Avaya IP phones. Avaya IP phones use the IP address information to connect to a call server. Avaya IP phones use the call server TLV to report which call server it is connected to back to the switch. The call server TLV supports IPv4 addresses only. By default, the transmission of the call server TLV is enabled for all ports. File server TLV With the file server TLV, you can configure the switch to advertise the IP addresses of a maximum of 4 file servers to connected Avaya IP phones. Avaya IP phones use the IP address information to connect to a file server. Avaya IP phones use the call server TLV to report which file server it is connected to back to the switch. The file server TLV supports IPv4 addresses only. By default, the transmission of the file server TLV is enabled for all ports on switches. 58 Overview System Configuration July 2012 Comments? infodev@avaya.com

59 802.1AB integration Note: If your Avaya IP Handset uses SIP, 802.1AB (LLDP) TLVs do not provide all information for the IP Phone. You must specify a fileserver IP address TLV so the IP phone can download the SIP configuration information, because the IP Phone retrieves information related to the SIP domain, port number and transport protocol from the file server Q framing TLV With the 802.1Q framing TLV, you can configure the switch to exchange Layer 2 priority tagging information with Avaya IP phones. Because the 802.1Q framing TLV operates as an extension of the LLDP Network Policy TLV, you must enable the LLDP MED Capabilities and LLDP MED Network Policy TLVs for the 802.1Q framing TLV to function. By default, the transmission of the 802.1Q framing TLV is enabled for all ports on switches. Phone IP TLV Avaya IP phones use the phone IP TLV to advertise IP phone IP address configuration information to the switch. The phone IP TLV supports IPv4 addresses only.

89 ASCII Configuration Generator using ACLI ASCII Configuration Generator using ACLI The primary goal of the ASCII Configuration Generator (ACG) is to provide the users of the Ethernet Routing Switch 2500 Series with a tool that lets them easily modify configuration of a particular switch or stack. ACG generates an ASCII configuration file which reproduces the behavior of the current binary configuration file. The user can also rely on this function to maintain backup configurations, as well as use it as a reliable method for debugging the current configuration of a switch. Important: When you are connected to a stack form the console port, ensure that the console is on the base unit before downloading an ASCII file. The Ethernet Routing Switch 2500 Series can download an editable ASCII configuration file from the TFTP server. You can load the ASCII configuration file automatically at start time or on demand using console menus or ACLI. After the editable ASCII configuration file is downloaded, the configuration file automatically configures the switch according to the Command Line Interface (ACLI) commands in the file. The maximum size for an ASCII configuration file is 100 KBs; larger configuration files must be split into multiple files. For more information about loading the ASCII configuration file automatically, see Automatically loading configuration file using ACLI on page 87. The commands that are associated with ACG are: show running-config command on page 89 copy running-config tftp command on page 94 show running-config command To display the current configuration of the switch or stack, use the show running-config command in Privileged EXEC command mode. The syntax of this command is: show running-config[verbose] [module <value>] You can enter [module <value>] parameters individually or in combinations. Important: If the switch CPU is busy performing other tasks, the output of the show running-config command can appear to intermittently stop and start. This is normal operation to ensure that other switch management tasks receive appropriate priority. The following table defines optional parameters that you can enter after the show runningconfig command. Overview System Configuration July
