provides information about the Avaya M770 ATM Switch, and the features that this software release supports. Note: This User Guide describes only the ATM functionality of the Avaya M770 chassis. • Information about the Avaya M770 chassis' safety considerations, architecture, main chassis control panel, M-SPV/M-SPX/M-SPS supervisor modules, power supplies and fans is available in the Avaya M770 User Guide. • Detailed information about the 10M/100M/1Gigabit Ethernet, M-SPV/M SPX/M-SPS supervisor, and M-MLS multilayer module can be found in their respective Installation Guides About the Avaya M770 ATM Switch The M770 ATM switch is a high-performance distributed Asynchronous Transfer Mode (ATM) switch that is designed for building and campus backbone applications, high-performance centralized servers, and power-user environments. Its advanced architecture can support very high traffic loads with no data loss or breaks in communication. The M770 ATM Switch also implements LAN Emulation (LANE) components. LANE enables legacy LAN applications to use a transparent ATM transport medium. In this way, end-stations on existing LANs can communicate with ATM end-stations. The M770 ATM Switch supports a range of option modules that enable you to customize the switch to fulfil applications that are appropriate to your networking requirements. It is designed as a software-upgradeable product. Therefore, you can expand the functionality of the switch by downloading new software. Avaya M770 ATM Switch User's Guide 1 Chapter 1 Introduction Master Agent and Sub Agent The M770 ATM Switch is a fully distributed ATM switch. Each module has its own switching and CPU power. In order to present the switch as a single and united entity, one module is automatically elected as a Master Agent while the other modules are Sub Agents. The Master Agent status is shown by the Network Management Agent (NMA) LED. The Master Agent is the module hosting the Management LEC with all its functionality: IP address and switch-wide information. The Master Agent is also a regular module with all the functionality of a Sub-Agent such as controlling the physical ports, virtual ports and download. The Master and Sub Agents have slightly different CLI options. For example, the Master Agent has the "ip" command and the "access" command which will enable you to access a Sub Agent from the Master Agent. A simple way to find out whether you are currently communicating with a Master Agent is to type help at the command line and check whether there is an "access" command option. All the information configured to the Master Agent (IP, ATM Prefix) is backed up by all the Sub Agents, so if the Master Agent is removed, another module will be elected and all previous configuration settings will be kept.

This includes an overview of the management and configuration tasks that you should perform soon after installation. Powering up the Avaya M770 ATM Switch During the system startup of an Avaya M770 ATM Switch, the switch automatically performs a number of self-tests on its internal hardware. The startup process is documented in each module's Installation Guide which includes information about the self-tests that are carried out and how the LED indicators on the switch indicate the status of the self-tests. If any non-critical hardware self-test fails then the Boot Loader will be entered. From the Boot Loader you may be able to diagnose and remedy the problem. For more information on how to use the Boot Loader, see Appendix B Using BOOT Loader. If the M770 ATM Switch passes all the self-tests, it will load the main image from flash memory and you can manage the M770 ATM Switch. Managing an Avaya M770 ATM Switch The M770 ATM Switch can be configured and managed using the following management methods: • Management from a local or remote console using the command-line interface. • Management from a network management station using SNMP and the Avaya M770 Manager which is an easy-to-use, graphical management application. Management from a local or remote console You can manage the M770 ATM Switch using the following methods: • Out-of-band console management by means of a VT100-compatible terminal connected to the serial port (labelled Console) of the M770 ATM module. • Remote console management using a terminal using Telnet over TCP/IP • Out-of-band console management using a VT100-compatible terminal connected to the serial port (labelled Console) of the M-SPV/M-SPX/M-SPS Supervisor module. For information about connecting a terminal device to the serial interfaces, refer to each module's Installation Guide. Avaya M770 ATM Switch User's Guide 9 Chapter 2 Getting Started Management from a network management station You can manage the M770 ATM Switch using SNMP management running over UDP/IP over an Emulated LAN (ELAN). • Connect the management station to the ELAN that the management LEC is connected to, or make sure it can communicate with that ELAN. • Set the IP address of the M770 ATM Switch management LEC, and make sure the management station is either on the same subnet or can communicate with that subnet. If the management station and management LEC are on different subnets, set the default gateway on the M770 ATM Switch so it can communicate with the management station. • Make sure you know the SNMP community name (for both read and write access). • Operate the Avaya M770 ATM Switch Manager on your management station as part of the CajunView package. The Avaya M770 ATM Switch Manager enables you to view the device, check the status indicators from the management station, and perform a range of management tasks. For more information about Avaya M770 ATM Switch Manager, refer to the Avaya M770 ATM Switch Manager User Guide. Setup Procedures on an Avaya M770 ATM Switch To install an M770 ATM Switch successfully, do the following: • To access and manage an M770 ATM Switch remotely, an IP address must be assigned to the switch. For more information on setting up an IP address on an M770 ATM Switch, see "Setting the IP address" on page 11. • To access an attached device or switch, set up static routing entries to switches that do not support PNNI and to any attached devices that do not support ILMI. For more information on setting up a routing table on an M770 ATM Switch, see Chapter 9, "Managing Static Routing". • To enable an attached device or switch to communicate, you may need to configure ports. For more information on configuring ports on an M770 ATM Switch, see "ATM Port Configuration" on page 12. • To enable communication over the network - LAN Emulation must be set up on the switch. For more information on setting up LAN Emulation on an M770 ATM Switch, see "Setting up LAN Emulation" on page 16. 10 Avaya M770 ATM Switch User's Guide Chapter 2 Getting Started Setting the IP address To access and manage an M770 ATM Switch remotely, for example using Telnet or SNMP, an IP address must be set for the switch. You will need to decide whether the M770 ATM Switch will use BOOTP to acquire its IP address or whether you wish to set it manually. If you plan to use BOOTP, make sure a BOOTP server is on the same ELAN as the M770 ATM Switch management LEC, or there is a route from a BOOTP server to the ELAN. For more information about managing the Management LEC, see Chapter 11. You will need to set the IP address of the M770 ATM Switch to BOOTP (this is the default IP setting for a new M770 ATM Switch). The M770 ATM Switch will then attempt to learn its IP address using the BOOTP protocol. If you plan to set the IP address manually, first ensure that the terminal or terminal emulator is connected to the serial interface of the Master Agent. The IP address of the switch can only be seen on the Master Agent (the Master Agent module's "NMA" LED will light ON). For example, if you want to set the IP address to be 149.49.46.61 with a subnet mask 255.255.255.0, and a gateway IP address 149.49.46.150, you should perform the following steps: M15-155s8:/>ip address 149.49.46.61 255.255.255.0 M15-155s8:/>ip gateway 149.49.46.150 For more information about setting IP addresses, see "Configuring the Avaya M770 ATM Switch Address Information" on page 31. Note: Changing the IP address commands will take effect immediately, and will disrupt IP traffic (for example, Telnet or SNMP) that is going to the M770 ATM Switch. Avaya M770 ATM Switch User's Guide 11 Chapter 2 Getting Started ATM Port Configuration Setting the virtual port to its default configuration If you are attaching an end-station or an edge device that supports ILMI to an Avaya M770 then you must ensure that the virtual port on the M770 ATM Switch is using its default configuration. For a list of the default port settings, see Appendix A, "Default Settings on a New Avaya M770 ATM Switch". For example, to set vport 8.4.0 to its default settings type: M15-155s8:/>vport disable 8.4.0 M15-155s8:/>vport reset all 8.4.0 M15-155s8:/>vport enable 8.4.0 This will enable ILMI to automatically configure the virtual port so that it can communicate with the attached device. For more information on resetting the parameters on the virtual port, see "Resetting Virtual Port Parameters" on page 75. Connecting to a device, supporting ILMI If you are attaching an end-station, edge device or another ATM switch which supports ILMI then the M770 ATM Switch will automatically configure the virtual port to communicate with the attached device. Ensure that ILMI is enabled on all devices and the ports have been set to their default port configuration before attaching the device. ILMI will not alter any parameters that have been manually configured by the administrator. If a parameter has been automatically configured for a port, using ILMI, the parameter will be displayed with an asterisk "*" next to it. Connecting to a device not supporting ILMI If you are attaching an end-station, edge device or another ATM switch that doesn't support ILMI to an Avaya M770, then you must disable ILMI on the M770 ATM Switch port that connects the two devices. You should then verify that the following virtual port parameters on the M770 ATM Switch are the same as the parameters on the attached device: • The port profile must be set to either "network" or "user" (the opposite to the configuration on the remote device). • The signalling stack type must be set to either UNI 3.0, UNI 3.1, UNI 4.0, IISP 3.0, IISP 3.1 or PNNI 1.0 (according to the configuration on the remote switch). • Other signalling parameters on the M770 ATM Switch to match the remote device like VPI and VCI range. 12 Avaya M770 ATM Switch User's Guide Chapter 2 Getting Started For example, if you are connecting an Avaya M400 Gate Switch LSA+ module which does not support ILMI, to port 8.4.0 on the M770 ATM Switch, you should configure port 8.4.0 on the M770 ATM Switch by performing the following steps: M15-155s8:/>vport disable 8.4.0 M15-155s8:/>vport disable 8.4.0 ILMI M15-155s8:/>vport set stacktype 8.4.0 UNI 3.0 M15-155s8:/>vport set vpirange 8.4.0 [0..0] M15-155s8:/>vport set vcirange 8.4.0 [32..1023] M15-155s8:/>vport enable 8.4.0 Routing Configuration PNNI Configuration When you configure your network you have to decide whether you're going to use a single peer group (flat) configuration or multiple peer groups (hierarchy) configuration. In case you have devices that do not support PNNI, please refer to Section Connecting to another ATM switch which doesn't support PNNI. Flat PNNI Configuration Connecting to another ATM switch which supports PNNI If you are attaching another ATM switch that supports PNNI ensure that the following conditions exist: • All switches should have a different ATM prefix (although the network will work even if some have the same prefix). To check this in the ATM switch type: 'address prefix' (on the Master Agent modules). • All switches must have a different node_id. By default it will be taken from the switch address. • All switches, in the same peer group, must have the same pg_id • All switches in the same peer group must have the same level. To check the PNNI and ATM addresses of the switch, type one of the following commands: M15-155s8:/> summary info or M15-155s8:/> route pnni config show Note: Changing the PNNI 'level' also changes the first byte of the Node ID and the Peer Group ID. Avaya M770 ATM Switch User's Guide 13 Chapter 2 Getting Started Connecting to another ATM switch which doesn't support PNNI If you are attaching another ATM switch that doesn't support PNNI, you must configure a route to that switch. For example, if you are connecting a Collage 740 to port 8.5.0 on the M770 ATM Switch, you should configure the static routing table by performing the following steps: (assume that the partial ATM prefix of the Collage 740 is 39.04) M15-155s8:/>route add 39.04. 8.5.0 Configuring Hierarchical PNNI The following steps will help you in configuring your network into a hierarchy of peer groups. You will need a basic knowledge of PNNI. • Create a drawing of the network you want to achieve while completing the following steps: 1 Decide how many level of hierarchy you need. 2 Divide your switches into different peer groups. 3 Decide how many peer groups are grouped together in to the next level of hierarchy. 4 On each peer group, decide which node will be the Peer Group Leader (PGL). Or better, configure all switches to be capable of becoming a Peer Group Leader (assuming their software version supports this). The PNNI's Peer Group Leader Election protocol will determine the active PGL. 5 Repeat the steps 3 &4, until all peer groups of all switches are organized in the hierarchy. 6 Decide the level scopes of the different level, in the range of 1-104. A lower level should have a greater number. Note: In the CLI, levels are numbered 1,2,3…. where 1 indicates the lower level (the physical level in which the node resides), 2 indicates the next level in the hierarchy and so on. 7 Determine the switches' prefixes so they will match the organization into peer groups and the specified levels. There is an algorithm that can help you in determining the prefixes to match the hierarchy (see Appendix ). • Configure all switches' ATM Address prefixes as determine in step 7, and force their node IDs to match the prefix. The configuration is done on the Master Agent using the command: M15-155s8:/>/address prefix
