Configuring Bridging - Cisco Catalyst 8540 MSR Configuration Manual

Chapter 25 Configuring ATM Router Module Interfaces

Configuring Bridging

All PVCs configured on ATM router module interfaces are used for bridging.
To configure bridging on an ATM router module interface, use the following commands, beginning in
global configuration mode:
Command
Step 1 Switch(config)# interface atm card/subcard/port
Switch(config-if)#
Step 2 Switch(config-if)# atm pvc 2 vci interface atm
card/subcard/port vpi
Step 3
Switch(config-if)# bridge-group number
Step 4 Switch(config-if)# end
Switch(config)#
Step 5 Switch(config)# interface fastethernet
card/subcard/port
Switch(config-if)#
Step 6
Switch(config-if)# no cdp enable
Step 7
Switch(config-if)# bridge-group number
Step 8 Switch(config-if)# end
Switch(config)#
Step 9 Switch(config)# bridge number protocol ieee
Example
The following example shows how to configure bridging on a Catalyst 8540 MSR with a Fast Ethernet
interface module in slot 0, an ATM interface module in slot 1, and an ATM router module in slot 3.

Purpose
Specifies the interface on the ATM router module
to configure.
Configures a PVC.
Note The VPI number on the ATM router
module interface must be 2.
Assigns the interface to a bridge group.
Returns to global configuration mode.
Specifies the Fast Ethernet interface to configure.
Disables Cisco Discovery Protocol on the
interface.
Assigns the interface to a bridge group.
Returns to global configuration mode.
Specifies the IEEE 802.1D Spanning-Tree
Protocol for the bridge group.
