5 Chapter 1: New in this release The following sections detail what is new in Avaya Ethernet Routing Switch 4000 Series Documentation for Release 5.6. Features See the following sections for information about new features in Release 5.6. Cisco CLI Phase 1 In Release 5.6 selected ACLI commands for ARP, Spanning Tree, and VLAN have been modified to use Cisco CLI syntax. While the interface software remains backwards compatible, and ASCII configuration files you created prior to Release 5.6 will function normally, from Release 5.6 and up the new Cisco CLI command syntax will be used for the commands for ARP, Spanning Tree, and VLAN. Disable MAC Learning You can use Disable MAC Learning on a port when you want to control the Layer 2 Forwarding Database (FDB) entries to prevent MAC tables from filling unnecessarily. You use Disable MAC Learning in combination with Static MAC FDB Entry. Equal Cost Multi Path (ECMP) Routers use Equal Cost Multi Path to determine equal cost paths to the same destination prefix to enable traffic load sharing and faster convergence to other active paths in case of network failure. Internet Group Management Protocol (IGMP) Querier When you configure IGMP Querier the system sends IGMP general queries to designated sources when the switch or VLANs operate in Layer 2 mode. IGMP Querier sends IGMP Avaya ERS 4000 Series Documentation Roadmap December

6 New in this release general queries to all ports, Multi-Link Trunks (MLT), Distributed Multi-Link Trunks (DMLT), and Link Aggregation Groups (LAG) on the configured VLAN Internet Group Management Protocol (IGMP) version 3 Snooping and Proxy From Release 5.6 and up the switch supports full IGMPv3 Snooping and Proxy. IGMPv3 Snooping provides the ability to pack multiple group members in a single report message to reduce the amount ot network traffic. When you enable IGMPv3 Snooping, you can use IGMP proxy to receive and consolidate multiple reports for the same multicast group. IP Phone automatic PoE changes PoE settings and IP Phone discovery have been enhanced to allow the provision of PoE priority levels and power limits when the system discovers an IP Phone. Layer 3 Brouter Port From Release 5.6 and up, the switch supports the configuration of brouter ports. A brouter port is a single-port VLAN that can route IP packets as well as bridge all non-routable traffic. An advantage of this feature is that it eliminates interruptions caused by Spanning Tree Protocol recalculations in routed traffic. Many to Many Port Mirroring You can use Many to Many Port Mirroring to monitor more than one traffic pattern because you can use multiple instances of port mirroring simultaneously. In a network that supports a variety of complex scenarious, when you can monitor multiple traffic patterns you can, for example, set up one port mirror to allow duplication of VoIP traffic for call recording processes and use another instance for intrusion detection while additional instances remain available for other activities or network troubleshooting. MLT/DMLT/LAG Dynamic VLAN changes Enhancements are made to Link Aggregation Groups (LAG) that provide consistent operation of Multi-Link Trunk (MLT), Distributed Multi-Link Trunk (DMLT), and LAGs so that you can make VLAN changes on trunks without disabling the trunk first. 6 Avaya ERS 4000 Series Documentation Roadmap December 2011 Comments? infodev@avaya.com

7 Features Network Time Protocol (NTP) The switch supports both Simple Network Time Protocol (SNTP) and Network Time Protocol (NTP) for time synchronization. You can configure SNTP and/or NTP with both primary and secondary server for SNTP and up to 10 servers for NTP, IPv4 and IPv6 for SNTP and only IPv4 for NTP. Ping Source Address For more flexible testing and network setup diagnostics, Ping has been enhanced so that you can specify the IPv4 source address of the outgoing ICMP request. The source address must be one of the active Layer 3 interfaces and you cannot specify the VRRP virtual address as the source address for Ping. Secure File Transfer Protocol (SFTP) For secure (SSH) software images Secure File Transfer supports download of Agent and diagnostic files and ASCII configuration file download and upload. SFTP allows secure transfer of a binary configuration file between a switch or stack and an SFTP server that uses SFTP with SSH version 2. Enabled by default, and available through ACLI and EDM, SFTP interacts with SSH Client. SFP Plus Release 5.6 introduces four Avaya ERS 4800 Series models that support Small Form factor Pluggable Plus (SFP+) devices. SFP+ supports 10 Gbps connectivity. The following SFP+ devices are supported: SFP+ order code AA E6 AA E6 AA E6 AA E6 AA E6 Description 1 Port 10 Gigabit-LR SFP+ (LC) Single mode up to 10 km 1 Port 10 Gigabit-ER SFP+ (LC) Single mode up to 40 km 1 Port 10 Gigabit-SR SFP+ (LC) Multi-mode fibre up to 300 m 1 Port 10 Gigabit-LRM SFP+ (LC) Multimode fibre up to 220 m SFP+ direct attach cable 10 m Avaya ERS 4000 Series Documentation Roadmap December

8 New in this release AA E6 AA E6 SFP+ order code Description SFP+ direct attach cable 3 m SFP+ direct attach cable 5 m Show Flash command You can use the show flash command to display FLASH capacity and current usage information about FLASH allocation and files, if present, to provide information about dual images and backup configurations. You can display the actual file sizes and space allocated to them. SSH Client Present only on switches with SSH images, and available only through ACLI, SSH Client uses SSH version 2. It is a secure shell protocol you can use to connect to an SSH Server device in the network that accepts remote connections. SSH RSA Authentication SSH RSA Authentication provides increased security for Secure Shell (SSH) login. With this feature, the switch supports RSA public-private key encryption that uses a digital certificate. SSH RSA Authentication is supported when you select the RSA certificate option for a Secure Shell connection from a client PC to the switch. Stack Health Monitoring and Recovery You can use Stack Health Monitoring and Recovery for more robust switch discovery and to obtain additional reports about stack communication failure. You can also use the recovery function to detect logical or software problems in a switch or stack. Static FDB MAC Entry You can use Static FDB MAC Entry to configure a static MAC address entry in the Layer 2 Forwarding Database (FDB). A static address does not age out and is saved in the configuration file. You use Static FDB MAC Entry in conjunction with Disable MAC Learning. 8 Avaya ERS 4000 Series Documentation Roadmap December 2011 Comments? infodev@avaya.com

9 Other changes Terminal Mode Permanent Setting When you use Terminal Mode Permanent Setting, the system saves terminal settings across login sessions. Retaining the terminal settings makes it easier to use scripts to configure or poll the switch. VLAN Scaling The switch supports up to 1,024 concurrent VLANs with VIDs in a range from 1 to VLAN scaling is an enhancement that enables actions on multiple VLANs simultaneously for faster configuration of a high number of VLANs. If you add multiple VLANs to a single port you must set VLAN configuration control to flexible. Voice VLAN Integration Voice VLAN is enhanced to provide centralized creation and management of Voice VLAN using VLAN-specific commands. The enhancement also includes the option to configure a statically allocated port that you can permanently assign to the Voice VLAN, where that port will still persist after a system boot. Another advantage of a statically allocated port is that it does not have to participate in the ADAC or 802.1AB discovery processes, when this behavior is desired. With Voice VLAN Integration, the switch creates static Voice VLANs and Layer 3 configurations can be applied as per standard operational procedures. Voice VLAN integration is specifically useful when Layer 3 configurations are needed for ADAC Voice VLAN. Other changes See the following sections for information about changes that do not apply to new features. New Avaya Ethernet Routing Switch 4000 Series models Release 5.6 introduces the following six new hardware models to the Avaya Ethernet Routing Switch 4000 Series: Avaya Ethernet Routing Switch 4550T-PWR+ Avaya Ethernet Routing Switch 4526T-PWR+ Avaya Ethernet Routing Switch 4850GTS Avaya Ethernet Routing Switch 4850GTS-PWR+ Avaya ERS 4000 Series Documentation Roadmap December

10 New in this release Avaya Ethernet Routing Switch 4826GTS Avaya Ethernet Routing Switch 4826GTS-PWR+ The new 4500 and 4800 PWR+ models support PoE+, according to the IEEE 802.3at standard, and can deliver power up to 32W, as opposed to 16W for the 4500 PWR legacy units. Release 5.6 also introduces one new removable power supply for the Avaya Ethernet Routing Switch 4000 Series the ERS4x00 PoE+ PSU, a stackable 1000W AC Power over Ethernet plus power supply unit. The PoE+ models include a 1000w power supply that enables full support for 48 ports when all ports are operating at class af PoE. On the new PoE+ hardware variants, the switch CPU speed is 533 MHz, and the FLASH is larger to allow for large images, backup images, and configurations. The standard ADS console port (DTE) on all new products is an RJ-45 Female Connector: (8 pin RJ45). Avaya Identity Engines Ignition Server Avaya Identity Engines Ignition Server (Ignition Server) is an 802.1X-capable RADIUS authentication server and TACACS+ server that grants or denies users access to your network based on your policies. When you use Ignition Server you can create a single set of policies that control access for all user connection methods: over a wired Ethernet jack, wireless, or VPN. Ignition Server also authenticates devices and you can configure an 802.1X authentication bypass for older devices on your network that cannot perform an 802.1X authentication. Diagnostic Auto Unit Replacement (DAUR) The DAUR feature is disabled in Release 5.6. You can download a diagnostic image through the download ACLI command. EDM enhancements Release 5.6 includes the following Enterprise Device Manager (EDM) user interface enhancements: a Save Config button was added to the Navigation tree toolbar to allow you to quickly and easily save a configuration a search function, called Auto Complete Search, appears just beneath the Navigation tree toolbar. You can use the entry field in this search function to help you find navigation tree 10 Avaya ERS 4000 Series Documentation Roadmap December 2011 Comments? infodev@avaya.com

25 Chapter 5: Task-based information Task-based information, a quick reference for using the Avaya Ethernet Routing Switch 4000 Series taskbased documentation, describes the structure of task-based information and how it can be used most effectively. Task-based documentation Task-based documentation is a new way of packaging customer information in a structured, task-centric format. Task-based documentation focuses on what the user must do and the sequence in which to perform tasks. The goal is to make Avaya documentation easy to find, easy to use, timely, and accurate. How to use task-based documentation In task-based documentation, procedural information is included in the document. Conceptual and reference information is provided, and the user is guided on how to use conceptual and reference material by identified prerequisites or direct links and references. The user navigates the information by following the flows that are provided for tasks and procedures. Task flow overview Task flows are flowcharts that illustrate which procedures and decisions are involved to complete an activity. The task flows guide you through activities to use the Avaya Ethernet Routing Switch 4000 Series, whether it is configuration, upgrading, installation, maintenance, or troubleshooting. Each flow provides the prerequisites and links to the tasks or procedures. To perform or refer to a procedure, always follow the task flow. Following the task flows ensures that you meet all the requirements for successful completion of the task. Avaya ERS 4000 Series Documentation Roadmap December

26 Task-based information Work flows, task flows, and procedures Work flows, task flows, and procedures have similar elements to maintain consistency and usability. Each of the following sections have a specific function: Purpose statements on page 26 Prerequisites on page 26 Work flows or task flows on page 26 Procedure steps on page 26 Example procedures on page 27 Variable definitions on page 27 Job aid on page 27 Purpose statements Purpose statements explain why or when you would perform a work flow, task, or procedure and impact. Prerequisites Prerequisites list everything you must do or understand before you start the workflow, task, or procedure. Prerequisites can include tasks that should already be completed, risks, confirmation of system status, required knowledge, time estimates or limitations, and links to supporting information. The prerequisite section is omitted if no required prerequisites exist. Work flows or task flows This section is the flow chart diagram that represents the task flow with navigational links to the tasks or procedures in the flow. Procedure steps Procedures provide numerical steps that help you perform the procedure. Each step is a single action. 26 Avaya ERS 4000 Series Documentation Roadmap December 2011 Comments? infodev@avaya.com
