Chapter 25 Configuring ATM Router Module Interfaces
Configuring LECs on ATM Router Module Interfaces (Catalyst8540 MSR)
To configure a LEC on an ATM router module interface, use the following commands, beginning in
global configuration mode:
Example
The following example shows how to configure two LECs on an ATM router module interface:
Switch# configure terminal
Switch(config)# interface atm 1/0/0.4 multipoint
Switch(config-subif)# ip address 40.0.0.1 255.0.0.0
Switch(config-subif)# lane client ethernet VLAN4
Switch(config-subif)# exit
Switch(config)# interface atm 1/0/0.5 multipoint
Switch(config-subif)# ip address 50.0.0.1 255.0.0.0
Switch(config-subif)# lane client ethernet VLAN5
Switch(config-subif)# exit
Switch(config)# router ospf 1
Switch(config-router)# network 40.0.0.0 0.255.255.255 area 0
Switch(config-router)# network 50.0.0.0 0.255.255.255 area 0
For more information on configuring LECs on ATM router module interfaces, see Chapter 14,
“Configuring LAN Emulation.” For a detailed description of LANE and its components, refer to
Cisco IOS Switching Services Configuration Guide: Virtual LANs.
LEC Configuration Examples
The examples in this section show how to configure LANE clients (LECs) on networks with two routers
and one Catalyst 8540 MSR. For detailed information on configuring the LANE server (LES), LANE
configuration server (LECS), and broadcast-and-unknown server (BUS), see Chapter 14, “Configuring
LAN Emulation.”
Caution For performance reasons, avoid configuring the LANE server components on ATM switch routers.
Instead, configure the LANE server components on a router such as a Cisco 7500 series router or a
Catalyst 5500 router with a LANE module installed.
Command Purpose
Step 1
Switch(config)# interface atm
card/subcard/port.subinterface# multipoint
Switch(config-subif)#
Creates the ATM router module
point-to-multipoint subinterface and enters
subinterface mode.
Note The ATM router module only supports
point-to-multipoint subinterfaces.
Step 2
Switch(config-subif)# ip address ip-address mask Provides a protocol address and subnet mask for
the client on this subinterface.
Step 3
Switch(config-subif)# lane client ethernet
elan-name
Enables a LANE client for an emulated LAN.
