This chapter provides procedures for using CiscoView to perform Asynchronous Transfer Mode LAN Emulation (ATM LANE) configuration on Catalyst 5000 series switches.
The LANE Manager feature allows you to display and configure LANE information on Catalyst 5000 series switches. On Catalyst 3000 series switches, you can only display LANE information; configuration tools are not available. For this reason, the Create, Configure, Modify, and Delete buttons might not appear in Catalyst 3000 series switch LANE Manager windows.
Where windows display optional fields, you can enter a value or leave the field blank to allow the device to automatically generate the value.
Before you begin configuring LANE, you must decide whether you want to set up one or multiple ELANs. If you set up multiple ELANs, you must decide where the LESs and LECs will be located and whether to restrict the LECs that can belong to each ELAN.
Only the tasks pertaining to configuring Catalyst 5000 series switch are provided in the following sections.
Follow the tasks in order to make maximum use of a Catalyst 5000 series switch to display ATM addresses. Displaying the ATM addresses of LESs and LECs as you configure them can save you the time and effort of computing the addresses. These savings can be considerable when you set up the LECS database---especially for ELANs with restricted membership. Restricted membership means that the LEC that asked to join this ELAN must pass other restrictions on this ELAN. Other restrictions are defined in the LECS database.
To configure LANE, complete these general steps:
Step 1 Read the following sections before beginning:
Step 2 Create a LANE plan and a worksheet for your own scenario. Determine the components to use, their locations, their associated VLANs, and the necessary redundancy features. Leave space for noting the ATM address of each LANE component on each subinterface of each participating device.
Your plan should include the following information:
Step 3 Decide whether to set up one or multiple ELANs. If you set up multiple ELANs, decide where the LES/BUSs and LECs will be located and whether you will restrict membership of the LECs that can belong to each ELAN.
You can configure some ELANs with unrestricted membership and some with restricted membership. You can also configure a default ELAN, which must have unrestricted membership.
Refer to "Setting Up the Database for Restricted-Membership LANs" in this chapter for additional information.
Step 4 Perform the steps in "Configuring a LANE."
Step 5 Perform the steps in "Checking the ATM configuration."
The following rules apply to assigning LANE components to the major ATM interface and its subinterfaces:
The following describes the LANE configuration on Catalyst 5000 series switches:
Before a LANE can be configured, the device must be configured as a LECS, and the ATM address must be registered to an ATM switch.
This section contains the following instructions for configuring a LANE. First you must configure your Catalyst 5000 device to become a LECS, and you must register the device's ATM address to an ATM switch via the command line):
Before you begin implementing LANE, be aware of the following:
Display the default ATM addresses for the LECS, LES, BUS, and LEC from the command line, then perform these steps using CiscoView:
Step 1 Display the default LANE address and write down the address on the worksheet. Following is a list of locations for address information:
(a) ECS---go to the LECS Configuration window and write down the address entered in the Actual LECS Address field.
(b) LES/BUS---go to the LES/BUS Configuration window and write down the address entered in the Actual LES, BUS ATM Addresses field.
(c) LEC---go to the LEC Details window and write down the address entered in the LEC ATM Address: field. To display the MAC address, click Address Mapping and write down the MAC address.
Step 2 Repeat Step 1 for each switch that participates in LANE and write down the displayed addresses on the worksheet.
Step 3 Click Cancel to exit the window.
This section contains instructions for performing the following:
On any Catalyst 5000 series switch, you can set up one or multiple LECS for multiple ELANs. You can set up an LECS for a given ELAN to participate in that ELAN. After you set up the interface for the VLAN, you must link the VLAN number with the ELAN name.
To set up only an LECS for an ELAN, perform the following steps:
Step 1 From the LECS Management window, click Create. The LECS Creation window opens.
Step 2 Specify the configuration for the LECS, including the following:
Step 3 Click Create to save the input.
Step 4 Click Cancel to exit the window.
To configure a switch as the LECS for multiple ELANs with unrestricted membership, complete the following steps:
Step 1 From the LECS Management window, select the default LECS.
Step 2 Click Database. The LECS Database window opens.
Step 3 Click Create. The Database Creation window opens.
Step 4 Create a named database for the LECS and click Create to save the name.
Step 5 Click Cancel to exit the window and return to the LECS Database window.
Step 6 Click Configuration and select the LES category. The Database Configuration---LES Category window opens.
Step 7 Bind the name of the first ELAN to the ATM address of the LES for that ELAN.
Step 8 Bind the name of the second ELAN to the ATM address of the LES.
Step 9 Repeat Steps 7 and 8, providing a different ELAN name and an ATM address for each additional ELAN in this switch cloud.
Step 10 (Optional) Specify a default ELAN for LECs not explicitly bound to an ELAN.
Step 11 Click Modify to save the input and exit the window.
Those LEC database entries specify the LECs allowed to join the ELAN. When an LEC requests the LECS to indicate which ELAN it is to join, the LECS consults its database and then responds as configured.
When LECs for the same restricted-membership ELAN are located in multiple switches, each LEC ATM or MAC address must be linked explicitly with the name of the ELAN. As a result, you must configure as many LEC entries (Step 4 in the following procedure) as there are LECs for ELANs. Each LEC has a different ATM address in the database entries.
To set up the LECS for ELANs with restricted membership, perform the following steps:
Step 1 From the LECS Management window, select the default LECS.
Step 2 Click Database. The LECS Database window opens.
Step 3 Click Create. The LECS Database Creation window opens.
Step 4 Create a named database for the LECS, click Create to save the name, exit the window, and return to the LECS Database window.
Step 5 Click Configuration and select the LES category. The Database LES Configuration window opens.
Step 6 Use Create to bind the name of the first ELAN to the ATM address of the LES for that ELAN.
Step 7 Bind the name of the second ELAN to the ATM address of the LES.
Step 8 Repeat Steps 6 and 7, providing a different ELAN name and an ATM address for each additional ELAN in this switch cloud.
Step 9 (Optional) Specify a default ELAN for LECs not explicitly bound to an ELAN.
Step 10 Add a database entry associating a specific LEC ATM address with a specific restricted-membership ELAN.
Step 11 Click Modify tosave the input in the window and exit the window.
Step 12 Repeat Steps 4 through 11 for each LEC with restricted-membership ELANs on this switch cloud. Specify the LEC ATM address and the name of the ELAN with which it is linked.
For each switch that participates in LANE, you must set up the necessary LES for each ELAN. BUSs are created automatically when the LES is created.
Once the LES and BUS have been set up, display and record the LES and BUS ATM addresses. Be sure to keep track of the interface where the LECS will eventually be located.
If there is only one default ELAN, you need to set up only one LES. If multiple ELANs are required, set up the LES for another ELAN on a different subinterface on the same interface---or place it on a different switch.
To set up the LES/BUS for an ELAN, complete the following steps:
Step 1 From the LES/BUS Management window, select an ELAN and click Create. The LES/BUS Creation window opens.
Step 2 Specify the parameters for the first ELAN.
Step 3 Click Create to save the change(s).
Step 4 Repeat Steps 2 and 3 for all other ELANs on this module.
Step 5 Click Cancel to exit the window.
Follow these steps to confirm configuration has been completed correctly.
Step 1 Select a module, and then select Configure>card. The Physical category information for the module is displayed. Verify that the module and and its associated fields associated with the model are correct.
Step 2 Select a port, and then select Configure>port. The Physical category information for the port is displayed. Verify that the status fields and their associated port are correct.
Step 3 Select an ATM port, and then select Configure>port. The Physical category information for the port is displayed. Verify that the ATM address information is displayed. Then, from the ATM Configuration menu, select the ELAN Table submenu and verify the information on configured ELANs.
Step 4 Open the Monitoring window. Display the message log information for the switch device. Pay special attention to ATM type messages recorded in the log. If possible, screen capture the message log or make note of ATM related messages for future references.
Step 5 Clear the message log buffer using the Clear Logs command at the bottom of the message display log screen.
Step 6 If necessary, reconnect Catalyst 5000 series switch back into your network topology and channel the normal data flow back to them. If reconnecting the switches into your network, be sure the link LEDs are lit for each of the connected 10BaseT ports.
Step 7 Check your network health monitoring equipment (if available) to ensure that the network is running cleanly. Check attached network devices for any obvious signs that the flow of data is being impeded.
Step 8 From each Catalyst 5000 series switch containing ATM modules, log back into the console, go to the Statistics menu, and display the message log. Pay special attention to ATM-specific messages. Compare the ATM-specific messages present in the log to the messages recorded previously. If needed, consult with Cisco support for an explanation of the different messages and their importance. Click Return to exit the display and return to the Statistics menu. Repeat this for each switch.
Step 9 From the CiscoView Main menu, select the whole device, select Configure>device, and access each of the Table categories to verify the address tables on each Catalyst 5000 series switch.
Step 10 Check the health of the network and the message log on each Catalyst 5000 series switches involved. If you see any irregularities are seen, investigate them immediately and, if needed, contact Cisco support.
After configuring LANE components on an interface or any of its subinterfaces, on a specified subinterface, or on an ELAN, display the LANE component status.
To show LANE status, perform the following steps:
Step 1 From the LECS Management window, click VC Connection to display the LES/BUS Creation window for the LECS configured on any interface. Due to space limitations, the ATM addresses for both parties of a selected VC Connection entry are displayed when you click Details in the LES/BUS Creation window. This displays the LES/BUS Creation window.
Step 2 From the LECS Management window, click Creation to display the LES/BUS Creation window, and then click LECS Database to display the LECS Database window. From the LECS Database window, select each of the categories to display the configuration window for each category.
Step 3 From the CiscoView Main menu, select the device, and then select Configure>device>ARP Table category to display the LANE ARP table of the LEC configured on the specified subinterface or ELAN.
