Chapter 7 Troubleshooting LAN Emulation Switching Environments
Initial Troubleshooting of LANE
Step 4 Check the ATM address of this LECS field. This ATM address should match the ATM address in the
LANE configuration server displayed in Step 1.
Step 5 Within the LE BUS section of the display, check the ELAN name field. It should match the name
configured. To determine the ELAN name, use the show lane database command and check the default
ELAN field.
Step 6 Check the ATM Address field. This ATM address should match the address displayed in the LANE
Server field shown in Step 1. The ATM address is appended with the corresponding subinterface number
in hexadecimal.
If any of these fields do not match the actual LANE configuration, refer to the “Configuring LAN
Emulation” chapter in the ATM Switch Router Software Configuration Guide and correct the
configuration.
Checking LANE Client Configuration
Use the following command to troubleshoot the LANE client connectivity:
Follow these steps to confirm the configuration and status of the LANE client:
Step 1 Use the show lane client command to confirm the LANE client.
Note This example shows how to confirm the LANE client configuration at ATM subinterface
13/0/0.1 on a switch router. Use the same command to confirm LANE client configurations
on the Catalyst 5000 or 6000 ATM modules.

Note This same information appears in the previously described show lane command.
Step 2 Check the ELAN name field. This should match the ELAN name configured.
