17 1 Overview ATM Uplink Module Overview The ATM (Asynchronous Transfer Mode) Uplink module provides LAN Emulation (LANE) and RFC 1483 connectivity over an ATM network. The module comes in four varieties: 2-port SONET (Synchronous Optical NETwork)/SDH (Synchronous Digital Hierarchy) OC-3c/STM-1 SMF (Single Mode Fiber) 2-port SONET/SDH OC-3c/STM-1 MMF (MultiMode Fiber) 2-port SONET/SDH OC-12c/STM-4c SMF 2-port SONET/SDH OC-12c/STM-4c MMF Each module has two physical interfaces capable of being simultaneously active. Table 1 lists the modules wavelengths. * Note: All wavelengths are nominal. Table 1. Wavelengths Module OC-3 MMF OC-3 SMF OC-12 MMF OC-12 SMF Wavelength 1310nm/2 KM 1310nm/10 KM 1310nm/500 M 1310nm/10 KM The major features of the ATM Uplink module are: LANE V2 Client - with LANE 1 compatibility RFC 1483 Support for up to 128 LANE Clients and RFC1483 VSPs total Avaya P550R/P580/P880/P882 Multiservice Switch ATM Uplink Module User Guide, Version

18 Chapter 1 QoS (Quality of Service) support for Unspecified Bit Rate (UBR), non real-time Variable Bit Rate (nrt-vbr), real-time Variable Bit Rate (rt-vbr), and Constant Bit Rate (CBR) UNI Signaling (User-to-Network Interface) version 3.0, 3.1 and 4.0 signaling ILMI 4.0 (Integrated Local Management Interface) version 4.0 PNNI (Private Network - to - Network Interface) non-transit mode Link Failover (UNI and RFC1483) FailOver and LoadShare (RFC1483)(80 Series modules only) Spanning Tree (per VLAN with LANE Clients only) Random Early Detection (RED) 80 Series Module (L3 Routing on the module) Multiple ATM Uplink Modules OAM Support Dual OC12/OC3 ports for a maximum of 1.244Gbps/ 310Mbps throughput. * Note: All ATM protocols are ATM Forum compliant. Communications Overview LANE The ATM Uplink module allows Ethernet attached devices to communicate across an ATM network using LANE or RFC The ATM Uplink module supports LANE V1 and V2 clients. Each ATM Uplink module has two physical ports. Each of these ports can connect to any network node of an ATM cloud. Depending on configuration, the links act as primary and backup links, or connections are load shared across both ports. The basic function of the LANE protocol is to simulate a connectionless LAN service over a connection-oriented ATM network. There are four basic components of LANE: 1-2 Avaya P550R/P580/P880/P882 Multiservice Switch ATM Uplink Module User Guide, Version 2.0

19 Overview LEC (LAN Emulation Client) - An entity in an end system that performs data forwarding, address resolution, and other control functions. A LEC also provides a standard LAN service interface to any higher-layer entity that interfaces to the LEC. Each LEC is identified by a unique ATM address, and is associated with one or more Media Access Control (MAC) addresses reachable through that ATM address LECS (LAN Emulation Configuration Server) - An entity that assigns individual LANE clients to particular Emulated LANs (ELANs) by directing them to the LAN Emulation Server (LES) that corresponds to the ELAN. There is logically one LECS per administrative domain, and this serves all ELANs within that domain. LES (LAN Emulation Server) - An entity that implements the control function for a particular ELAN. There is only one logical LES per ELAN, and it is identified by a unique ATM address. BUS (Broadcast and Unknown Server) - A Multicast server used in ELANs to flood traffic addressed to an unknown destination and to forward multicast and broadcast traffic to the appropriate clients. The basic concepts are consistent between LANE V1 and LANE V2, however, there are some differences between them. The main difference is that LANE V2 provides QoS support and multiplexing of Virtual Circuits (VCs). LANE is one of the mechanisms the ATM Uplink module uses to simulate a LAN over the ATM network. By implementing a LANE client in the ATM Uplink module, the ATM network can seamlessly provide connectionless LAN and multicast capabilities to the rest of the Ethernet LAN. The logical topology of the ATM Uplink module interfaces is different from the physical connections. LECs are configured on the ATM Uplink module. A LEC is not associated with a physical port, but instead is associated with a LANE server that forms an ELAN. A LEC is treated similarly to an Ethernet port of the Avaya system and is associated with a Virtual LAN (VLAN). A LEC is represented and configured as a switch port in the Avaya switch. Each VLAN may have only one LEC per ATM Uplink module, and each module may have only one LEC per ELAN. Avaya P550R/P580/P880/P882 Multiservice Switch ATM Uplink Module User Guide, Version

20 Chapter 1 RFC 1483 RFC 1483 defines an encapsulation method for transporting multiple protocols over the same or different VCs using the ATM Adaptation Layer 5 (AAL5) protocol. Implementation is limited to Permanent Virtual Circuits (PVCs). The ATM Uplink module supports Ethernet, as well as a routed Protocol Data Unit (PDU) for layer 3. The ATM Uplink module supports up to 128 Virtual Switch Ports (VSPs) and LECs per module. A VSP is a single port on an ATM Uplink module within the Avaya P550/P880 switch. It appears as a switch port to the supervisor module and is bound to a VLAN by the supervisor. Only one VSP may be bound to a particular VLAN per ATM Uplink module. * Notes: 50 Series modules require a license key in order to use RFC Series modules are preconfigured for RFC1483 support. If you have a 50 Series ATM Uplink module, refer to the Avaya P550/P880 Switch ATM Uplink Installation Sheet for more information on the license key. You can configure a module with both LANE and RFC Series require you to purchase an RFC 1483 license key for this feature. Quality of Service QoS (Quality of Service) is a guarantee of throughput across a network. It provides multiple levels of service based on user configured parameters. QoS is implemented in LANE by configuring sets of ATM traffic parameters (QoS Sets) and associating these parameters with different Ethernet frame priorities (0-7). A Data Direct Virtual Channel Connection (DDVCC) is set up to a QoS capable LEC for each QoS Set as needed. A QoS Set consists of descriptors (PCR, SCR) that define traffic behavior for a given category (CBR, rtvbr, nrtvbr and UBR). A QoS Domain is a set of rules for mapping Ethernet frame priorities to ATM QoS Sets. A QoS Domain also consists of a series of QoS Sets and their priority mappings. 1-4 Avaya P550R/P580/P880/P882 Multiservice Switch ATM Uplink Module User Guide, Version 2.0

21 Overview In an RFC 1483 environment, each PVC has its own set of QoS parameters. Traffic priority to channel mapping is done through a link that groups up to eight channels to a common ATM end point. UNI Signaling User-to-Network Interface Signaling (UNI) dynamically creates and removes Switched Virtual Connections (SVCs) in an ATM network. The higher layer ATM protocols, specifically LANE, use the UNI signaling for connectivity. ILMI 4.0 The Integrated Local Management Interface (ILMI) protocol provides the ATM Uplink module with status and configuration information across the user-to-network interface. This information includes ATM network prefixes, registered services, and capabilities. PNNI Private Network-to-Network Interface (PNNI) is a dynamic routing protocol that manages and allocates network resources for SVCs in an ATM network. Because the ATM Uplink module implements PNNI in non-transit mode, the ATM Uplink module does not act as an intermediate ATM switch in an ATM network. This provides high-performance edge access and load-sharing. PNNI provides the ability to distribute topology information throughout the network. The ATM Uplink module is capable of having multiple active links, so PNNI is used to make routing selections to optimize link utilization and provide load sharing. When a connection with specific QoS parameters is requested, PNNI is able to dynamically find a path (if any) satisfying the request, allocate the necessary resources in the network, and provision the connection. PNNI enables the network to respond quickly to link failures, link recoveries, and changing network loads on any link. The network is able to adapt to changes in the addressing of a network or the topology of the network as switches are added or deleted.

22 Chapter 1 Link Failover * Note: Link Failover applies to RFC1483 and UNI links only. In networks that do not support PNNI, you can use link failover as an alternative to multiple active interfaces. With this feature, one link is active with all other links designated as standby. If one link loses its connectivity, a standby link becomes active and the connections are re-established. Links are weighted to determine which link attempts to take over first. Spanning Tree The Spanning Tree protocol is used to prevent loops from forming in your network. The spanning tree algorithm creates a single path through the network by ensuring that if more than one path exists between two parts of a network, only one of these paths is used, while the others are blocked. Because of the number of bridges present in a switched networking environment, spanning tree structures can become extremely complex. The ATM Uplink module supports the spanning tree per VLAN option (each LEC has an independent STP state). The Web Agent may display what appears to be misleading Spanning Tree Protocol information. When you are using UNI on both (physical) ports on the ATM Uplink module, traffic may flow through either (physical) port 1 or (physical) port 2, depending on path cost. The Spanning Tree information on the Web Agent will indicate that Port 1 of the ATM Uplink module is active and forwarding traffic. This is because from the switch s perspective, it sees the LEC as a Virtual Switch Port, not the actual physical ports. So regardless of which physical port is passing the traffic, the LEC (Virtual Switch Port) is seen as active. * Note: Each VLAN runs a separate spanning tree with its own Bridge Protocol Data Units (BPDUs). This allows each LEC to have a spanning tree state that is independent of the other LECs on its module and does not support spanning tree on RFC1483 connections. For more information on spanning tree support and configuration, refer to the Avaya P550R/P580/P880/P882 Switch User Guide. 1-6 Avaya P550R/P580/P880/P882 Multiservice Switch ATM Uplink Module User Guide, Version 2.0

23 Overview Random Early Detection (RED) 80 Series Module Random Early Detection (RED) provides a congestion control mechanism for TCP encapsulated data packets over ATM. A transport protocol (for example, TCP) detects congestion only after a packet has been dropped. When RED is NOT configured, packets are dropped when the queue at the outgoing link becomes full. When this happens, multiple hosts simultaneously decrease their transmission windows, regardless of how much each host contributes to the congestion. This results in synchronized peaks in traffic from multiple hosts, causing inefficient link utilization. RED monitors the average queue size and it statistically drops packets in congested conditions before the queue is full. Therefore, the hosts that generate more traffic during queue congestions most likely have more packet loss than hosts generating less traffic. See Appendix A for more detail The 80 Series ATM Uplink module is preconfigured to perform Layer 3 switching (routing) instead of forwarding routed traffic to the supervisor module. In a chassis loaded with only 80 Series modules, the backplane can run in Fabric Mode II (66MHz) instead of Fabric Mode I (55Mhz). This increases the throughput of a switch port from 1.76Gbps to 2.11Gbps. 80 Series modules also provide 8 separate queues for better Quality of Service where each Ethernet priority has its own queue. Multiple ATM Uplink Modules You can install more than one ATM Uplink module in your Avaya P550R/P580/P880/P882 Multiservice Switch. Using multiple ATM Uplink modules provides the following advantages: Failover * Note: This is for LANE only. Avaya P550R/P580/P880/P882 Multiservice Switch ATM Uplink Module User Guide, Version

24 Chapter 1 By statically assigning the LECs of the same ELAN on different ATM Uplink modules to the same VLAN, per-vlan spanning tree provides failover. The forwarding port is the port with the lowest port ID. * Note: Hunt Groups are not supported. If you configure your network with Failover, you must be using per-vlan Spanning Tree. Failure to do so will result in broadcast storms which will take down your network. PNNI/UNI You can configure both PNNI and UNI. However, you cannot configure both on the same module. PNNI and UNI must be configured on different modules and you can configure either on multiple modules. More ATM Traffic Each module can support up to 128 virtual switch ports, therefore, you can direct more ATM traffic through your Avaya P550/P580/P880/P882 switch. * Note: For PNNI, you cannot load share between different modules, but you can load share between different ports on the same module. * Note: In RFC1483 mode, you can load share between two physical ports on the same ATM Uplink module. OAM Support The ATM Uplink module supports F5 (Virtual Circuit) Operation Administration, and Maintenance (OAM) cells. These cells are sent once per second down the default PVC in an ATM Link. These cells are used to check the integrity of a circuit (end-to-end). The device at the other end of the circuit should loop back these cells. Should an OAM cell not return, the ATM Uplink module detects a circuit failure and will fail over to the configured FailOver Link. OAM support is valid only on RFC1483 VSPs (not LAN Emulation Clients (LECs)). 1-8 Avaya P550R/P580/P880/P882 Multiservice Switch ATM Uplink Module User Guide, Version 2.0

32 Chapter 2 Downloading Application Code The ATM Uplink module supports two versions of application code as well as one version of boot code. In the event the module will not start using application code, the module can be started with boot code in order to run diagnostics and change the configuration. Boot code does not allow you to run ATM protocols and/or pass traffic. Application code supports the full feature set of the ATM Uplink module (features depend on the version of code you are running). Downloading application or boot code requires that you have a TFTP server running and a copy of the code you wish to download. Further, the TFTP server must be reachable through an IP Interface on one of the switch s data ports or the supervisor s Ethernet console port. The following procedure is applicable to downloading both application code as well as boot code. This procedure can also be accomplished via the command line interface. Refer to the ATM Uplink Module CLI Reference for more details. * Note: Once you have downloaded new code, the ATM Uplink module must be reset. This can be accomplished by resetting the entire switch or just the ATM Uplink module as explained below. 2-8 Avaya P550R/P580/P880/P882 Multiservice Switch ATM Uplink Module User Guide, Version 2.0

QoS (Quality of Service) is a measure of performance for a transmission system that reflects its transmission quality and service availability. A QoS Domain consists of a series of QoS Sets, their priority mappings, and the set of LECs to which these rules apply. A QoS Set is a set of signaling parameters that describe a traffic class. QoS parameters control the amount of traffic the source in an ATM network sends over a Switched Virtual Circuit (SVC). If any switch along the path cannot accommodate the requested QoS parameters, the request is rejected, and a rejection message is forwarded back to the originator of the request Avaya P550R/P580/P880/P882 Multiservice Switch ATM Uplink Module User Guide, Version 2.0

63 Configuring LANE Table 35. QoS Set Creation Parameters Parameter Traffic Class CDVT PCR Definition The traffic class for the set you are creating. Values include: UBR - Unspecified bit rate which is characterized in terms of Cell Delay Variation Tolerance (CDVT), and Peak Cell Rate (PCR). CBR - Constant bit rate. This is used by connections that request a static amount of bandwidth that is continuously available during the connection lifetime. This amount of bandwidth is characterized in terms of PCR, and Cell Delay Variation Tolerance (CDVT). rtvbr - Real-time variable bit rate. This is intended for real-time applications (voice and video). rtvbr connections are characterized in terms of PCR, SCR, and MBS. nrtvbr - Non-real-time variable bit rate. This is intended for non-real-time application that have bursty traffic characteristics and which are characterized in terms of PCR, Sustainable Cell Rate (SCR), and Maximum Burst Size (MBS). Note: Refer to Creating a QoS Class Set for more information. Enter the Cell Delay Variation Tolerance. When cells from two or more connections are multiplexed, cells of a given connection may be delayed. Simultaneously, cells of another connection are being inserted at the output of the multiplexer. Some randomness may affect the inter-arrival time between consecutive cells of a connection. The upper boundary on this delay is the CDVT. Enter the Peak Cell Rate. This is a traffic parameter specifying an upper bound on the rate at which traffic can be submitted on an ATM connection. The unit of measurement is cells/ second. The valid range is 100 to the maximum line rate. Avaya P550R/P580/P880/P882 Multiservice Switch ATM Uplink Module User Guide, Version

65 Configuring LANE Creating a QoS Set There are four different Service Categories that apply to QoS Sets. They are: UBR (Unspecified Bit Rate) - Allows any amount of data up to a specified maximum to be sent across the network, but there are no guarantees in terms of delivery, file transfer, Ethernet connectivity, cell loss rate, or delay. CBR (Constant Bit Rate) - Is used for connections that depend on precise clocking to ensure undistorted delivery. It is recommended that constant bandwidth is always reserved. rtvbr (real time Variable Bit Rate) - Is used for connections in which there is a fixed timing relationship between samples. This is a service category intended for time dependent, real-time applications (voice and video) with variable bandwidth. nrtvbr (non-real Time Variable Bit Rate) - Is used for connections in which there is no fixed timing relationship between samples, but the traffic still needs a guaranteed QoS. This service category is intended for non-real-time applications with variable traffic, guaranteed delivery, but not dependent on time. * Note: When attempting to establish non-ubr traffic class connections on the ATM Uplink module, the ATM switch to which the ATM Uplink module is connected may reject the initial connection request due to lack of resources. The ATM Uplink module retries the connection as UBR. Although this provides maximum connectivity, it may not provide the expected QoS. To create a QoS Set: 1. Select Modules & Ports > Configuration from the Web Agent. The Module Information dialog box opens (Figure 18). 2.

91 4 Configuring RFC 1483 Overview In an RFC1483 based solution, it is the responsibility of the device attached to the network to replicate and distribute packets to each remotely connected endpoint. In a LANE-based solution this function is handled by the BUS. The absence of this element (in RFC1483) means the following: The ATM Uplink module must replicate flooded (broadcast/ unknown) packets to all VCs in a broadcast domain. The ATM Uplink module can only learn the VC-relative location of end stations through the receive path. In other words, each learned MAC address is associated with the VC it received the Ethernet frame on. Ethernet considers every host on the same LAN segment to be in a Broadcast Domain. When one host transmits a Frame, every other host on in the Broadcast Domain receives and to some extent, processes the Frame. In an ATM network, devices pass traffic through point to point connections (VCs) making the distributing of a single Frame to every other destination cumbersome. To accomplish this Broadcast capability, you can either configure a VC from every device to every other device; hence creating a mesh topology. Or, as is the case for LANE, provide a BUS that all devices can forward traffic to if that traffic needs to go to all of the other devices in the Broadcast Domain. Virtual Switch Ports (VSP) The RFC1483 solution eliminates the need for LANE services. As such, you must configure at least one Permanent Virtual Circuit (PVC) to each destination in the ATM network for your Broadcast Domain. The collection of PVCs associated with the Broadcast Domain leads to the concept of a Virtual Switch Port (VSP). In the simple case where there are only two devices in the ATM network, the VSP need only send one copy of a Frame to the other device. Since the VSP does not need replicate the Frame for two or more destinations, the VSP is said to be Non-Replicating. Avaya P550R/P580/P880/P882 Multiservice Switch ATM Uplink User Guide, Version

92 Chapter 4 If there are two or more destinations in the Broadcast Domain, the VSP must replicate the Frame once for each remote destination. This is said to be a Replicating VSP. The Replicating option is specified when you create the VSP and cannot be changed without deleting the VSP and recreating it. ATM Links An ATM Link is a group PVCs that all connect to the same destination. In the simple case of a Non-LoadSharing configuration, you define one ATM Link per remote destination. PVCs for an ATM Link should all be configured on the same physical port. While you are permitted to configure PVCs on different physical ports, it is not recommended because it can lead to misconfigurations. If LoadSharing is enabled, you define two ATM Links per each destination. Each pair of Links will have PVCs on either physical port. For example, if you were connecting a site in Boston to a site in Tampa through the ATM cloud, you would configure Link1_BostonToTamp with PVCs on physical port 1 and Link2_BostonToTamp with PVCs on physical port2. Each link would have the other link as the FailOver link on the ATM Link configuration screen. Within each ATM Link, you define the PVCs with their parameters and assign Ethernet priorities to those PVCs. OAM Support The ATM Uplink module supports F5 (Virtual Circuit) Operation Administration, and Maintenance (OAM) cells. These cells are sent once per second down the default PVC in an ATM Link. These cells are used to check the integrity of a circuit (end-to-end). The device at the other end of the circuit should loop back these cells. Should an OAM cell not return, the ATM Uplink module detects a circuit failure and will fail over to the configured FailOver Link. OAM support is valid only on RFC1483 LLC and Simple Bridged VSPs (not LAN Emulation Clients (LECs) or RFC1483 Routed VSPs). FailOver and LoadShare FailOver allows you to configure two ATM Links that connect to the same destination; and, in the event the first link fails, the second (FailOver) link will forward the traffic. In this configuration, only one link is forwarding traffic. This may be desirable if you have two service providers and want to direct all traffic to the preferred provider. 4-2 Avaya P550R/P580/P880/P882 Multiservice Switch ATM Uplink User Guide, Version 2.0.

93 Configuring RFC 1483 LoadShare builds on the capabilities of FailOver. You configure two ATM Links but the ATM Uplink module will forward traffic down both Links. In the event of a failure on one link, the other will forward all traffic. * Note: Loadshare is only supported on 80 Series ATM Uplink modules. Non-Replicating VSP Example The use of a Non-Replicating VSP is appropriate when there are two sites in a network. If a business has two buildings with the Engineering VLAN and are using an ATM connection to join them, each site would configure a Non-Replicating VSP. All traffic leaving one site is destined for the other. Within the Non- Replicating VSP, each site would configure a single ATM Link; and that ATM Link would hold the configuration of each PVC. Site 1 Eng_Site_2 Eng_Site_1 Site 2 Engineering VLAN VSP Engineering ATM Network VSP Engineering Engineering VLAN Site 1 would create VSP Engineering with ATM Link Eng_Site_2. Within Eng_Site_2, you would define 1 or more PVCs. Site 2 would create VSP Engineering with ATM Link Eng_Site_1. Within Enge_Site_1, you would define the same set of PVCs. Both sites would bind the Engineering VSP to the Engineering VLAN. Failure to configure the same PVCs on both ends will result in traffic being lost since each site would not recognize the other s VCs. Avaya P550R/P580/P880/P882 Multiservice Switch ATM Uplink User Guide, Version

94 Chapter 4 Replicating VSP Example If a site had three buildings (or more), each site would configure a Replicating VSP. Building on the Non-Replicating VSP example above, suppose there were three buildings with the Engineering VLAN. Each of the three sites would create a Replicating VSP called Engineering. Each site would also configure two ATM Links and within those two links, define PVCs. Site 1 Eng_Site_2 Eng_Site_1 Site 2 Engineering VLAN VSP Engineering Eng_Site_3 ATM Network VSP Engineering Eng_Site_3 Engineering VLAN Site 3 Eng_Site_1 Eng_Site_2 Engineering VLAN VSP Engineering Site 1 would create VSP Engineering with ATM Links Eng_Site_2 and Eng_Site_3. Site 2 would create VSP Engineering with ATM Links Eng_Site_1 and Eng_Site_3. Site 3 would create VSP Engineering with ATM Links Eng_Site_1 and Eng_Site_2. All three sites would bind their Engineering VSP to the Engineering VLAN.

Click Apply to save your changes, or Cancel to restore previous settings. The ATM Uplink module allows you to manually configure LANE Address Forwarding Table (LAFT) entries. In the case of an RFC1483 Virtual Switch Port (VSP), you associate a destination MAC address with an ATM Link within the VSP. Traffic destined for that MAC address will flow down the appropriate PVC within the link based on frame priority/priority mapping. This feature is most beneficial when using multicast and/or broadcast MAC addresses. The Avaya Multiservice switch does not store multicast or broadcast MAC addresses in the AFT or the LAFT. Therefore, when a multicast destination is used, such as in OSPF, that Frame will always be forwarded by the Default PVC for the ATM Link which is priority zero. Given that you may want management traffic forwarded at a high priority, or at least at the priority it is tagged with, you need to enter Static LAFT entries.

108 Chapter 4 Configuring ATM Links within Virtual Switch Ports An ATM Link is defined within a VSP and it groups PVCs that end at the same destination. An ATM Link is the equivalent of a LANE ATM destination. Each ATM link has space for eight PVC entries to support priority based QoS in RFC1483 mode. After the PVCs have been defined in the ATM Link, you should make sure that each Ethernet priority is mapped to a PVC. As Ethernet traffic is sent, the ATM Uplink module will forward the various priority frames down the appropriate PVC. If you fail to map an Ethernet priority, traffic sent at that priority will be dropped. Each PVC in the ATM Link should terminate at the same remote interface. However, there is no enforcement of this restriction and you may configure the ATM Link so frames are forwarded to different remote interfaces based on priority. This is not recommended. If you are configuring two links that connect directly to each other, you must ensure that the same VP/VC numbers are used for the PVCs. Each ATM Uplink module supports a maximum of 16,000 ATM links. This section provides the information you need to configure ATM links for your virtual switch ports.
