LANE Configuration Tasks
Setting Up the Server, BUS, and a Client on a Subinterface
To set up the server, BUS, and (optionally) clients for an emulated LAN, perform the following steps,
beginning in global configuration mode:
If the emulated LAN in Step 2 will have restricted membership, consider carefully whether you want to
specify its name here. You will specify the name in the LECS’s database when it is set up. However, if
you link the client to an emulated LAN, and by some mistake it does not match the database entry linking
the client to an emulated LAN, this client will not be allowed to join this or any other emulated LAN.
If you do decide to include the name of the emula ted LAN linked to the client in Step 3 and later want
to associate that client with a different emulated LAN, make the change in the configuration server’s
database before you make the change for the client on this su binterface.
Each emulated LAN is a separate subnetwork. In Step 4, make sure that the clients of the same emulated
LAN are assigned protocol addresses on the same subnetwork, and that clients of different emulated
LANs are assigned protocol addresses on different subnetworks.
For examples of these commands, see LANE Configuration Examples, page 14-17.
Setting Up a Client on a Subinterface
On any given router or switch router, you can set up one client for one emulated LAN or multiple clients
for multiple emulated LANs without a server and BUS. You can set up a client for a given emulated LAN
on any routers you select to participate in that emulated LAN. Any router with clients for multiple
emulated LANs can route packets among those emulated LANs.
Command Purpose
Step1 Switch(config)# interface atm 0.subinterface#
[multipoint]
Switch(config-subif)#
Specifies the subinterface for the first emulated
LAN on this router.
Step2 Switch(config-subif)# lane server-bus {ethernet
| tokenring} elan-name1
Enables a LES and a LANE BUS for the first
emulated LAN. (The tokenring option is not
supported on the Catalyst 8540 MSR.)
Step3 Switch(config-subif)# lane client {ethernet |
tokenring} [elan-name1]
(Optional.) Enables a LANE client for the first
emulated LAN. (The tokenring option is not
supported on the Catalyst 8540 MSR.)
Step4 Switch(config-subif)# ip address ip-address mask Provides a protocol address for the client.
