Chapter14 Configuring LANEmulation
LANE Configuration Tasks
To set up a client for an emulated LAN, perform the following steps, beginning in global configuration
mode:
Note To route traffic between an emulated LAN and a Fast Ethernet (FE) or Gigabit Ethernet (GE) interface,
you must configure the LANE client on an ATM router module interface rather than a route processor
interface.
Each emulated LAN is a separate subnetwork. In Step 2, 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.
Note For Token Ring LANE environments that source-route bridge IP traffic to the ATM switch routers,
multiring must be configured to enable Routing Information Field (RIF) packets. For an example, see
Default Configuration for a Token Ring ELAN with IP Source Routing (Catalyst 8510 MSR and
LightStream 1010), page 14-31.
Example (Catalyst8540 MSR)
The following example shows how to configure a client for emulated LAN on an ATM router module
subinterface:
Switch(config)# interface atm 10/0/1.1
Switch(config-if)# ip address 172.16.4.0 255.255.0.0
Switch(config-if)# lane client ethernet elan_1205
For additional examples of these commands, see LANE Configuration Examples, page 14-17.
Configuring a LAN Emulation Client on the ATM Switch Router
This section explains how to configure a LANE client connec tion from the ATM switch router in the
headquarters building to the route processor interface (or optio nal ATM router module interface on the
Catalyst 8540 MSR) of the ATM switch router.
Command Purpose
Step1 Switch(config)# interface atm 0.subinterface#
[multipoint]
Switch(config-subif)#
or
Switch(config)# interface atm
card/subcard/port.subinterface# [multipoint]
Switch(config-subif)#
Specifies the route processor subinterface
number for an emulated LAN on this router.
If you are using the optional ATM router module,
specifies the ATM subinterface number.
(Catalyst 8540 MSR)
Step2 Switch(config-subif)# ip address ip-address Provides a protocol address for the client on this
subinterface.
Step3 Switch(config-subif)# lane client {ethernet |
tokenring} elan-name1
Enables a LANE client for the first emulated
LAN. (The tokenring option is not supported on
the Catalyst 8540 MSR.)
