Chapter 7 Troubleshooting LAN Emulation Switching Environments

Checking the Configuration Server Database

The LECS assigns individual clients to particular emulated LANs by directing them to the LANE server

that corresponds to the emulated LAN. The LECS maintains a database of LANE client ATM or Media

Access Control (MAC) addresses and their ELANs.

Note A LECS can serve multiple ELANs.

Use the following command in privileged EXEC mode to display the configuration of the LANE client

database binding:

Follow these steps to confirm the configuration of the LANE database:

Step 1 Use the show lane database command to display the default binding of the LANE database of the switch

router in the engineering building.

EngFl1Ls1# show lane database

LANE Config Server database table 'eng_dbase' bound to interface/s: ATM13/0/0

default elan: eng_elan

elan 'eng_elan': un-restricted

server 47.00918100000000E04FACB401.00E04FACB403.01 (prio 0)

EngFl1Ls1#

Step 2 Check the LANE Config Server database table field. It indicates the binding of the LANE client to the

LANE database.

Step 3 Check the server field. The ATM address displayed should correspond to the ATM address shown in the

show lane default-atm-addresses command in Step 1 of the previous section, “Checking Basic LANE

Configuration.”

If the LANE client configuration server database is set up incorrectly, refer to the “Configuring LAN

Emulation” chapter in the ATM Switch Router Software Configuration Guide.
