Chapter 24 Configuring ATM Router Module Interfaces

Configuring Multiprotocol Encapsulation over ATM

Note Traffic shaping and policing are not supported on the ATM router module interfaces; for traffic shaping and policing on ATM connections, use VP tunnels. For more information on VP tunnels, see Chapter 6, “Configuring Virtual Connections.”

To configure multiprotocol encapsulation over ATM on the ATM router module interface, use the following commands, beginning in global configuration mode:

 

Command

Purpose

Step 1

 

 

Switch(config)# interface atm

Creates the ATM router module

 

card/subcard/port.subinterface# multipoint

point-to-multipoint subinterface and enters

 

Switch(config-subif)#

subinterface mode.

 

 

 

 

Note The ATM router module only supports

 

 

point-to-multipoint subinterfaces.

 

 

 

Step 2 Switch(config-subif)# ip address ip-address mask

Enters the IP address and subnet mask associated

 

 

with this interface.

Step 3

 

 

Switch(config-subif)# map-groupname

Enters the map group name associated with this

 

 

PVC.

 

 

 

Step 4 Switch(config-subif)# atm pvc 2 vci-a[upc upc]

Configures the PVC.

 

[pd pd] [rx-cttr index] [tx-cttr index] interface

Note The VPI number on the ATM router

 

atm card/subcard/port[.vpt#] vpi-b vci-b

 

module interface must be 2.

 

[upc upc] encap {aal5mux1 aal5snap}

 

 

Step 5

Switch(config-subif)# exit

Returns to global configuration mode.

 

Switch(config)#

 

Step 6

 

 

Switch(config)# map-listname

Creates a map list by naming it, and enters

 

Switch(config-map-list)#

map-list configuration mode.

 

 

Step 7

 

 

Switch(config-map-list)# ip ip-address

Associates a protocol and address with a specific

 

{atm-nsap address atm-vc vci} [broadcast]

virtual circuit.

 

 

 

1.Only the Catalyst 8540 MSR enhanced ATM router module supports AAL5 MUX encapsulation.

Example

The following example shows how to configure RFC 1483 on an ATM router module interface, beginning in global configuration mode:

Switch(config)# interface atm 1/0/0.1011 multipoint

Switch(config-subif)#ip address 10.1.1.1 255.255.255.0

Switch(config-subif)# map-group net1011

Switch(config-subif)#atm pvc 2 1011 interface atm 3/0/0 0 1011 encap aal5snap

Switch(config-subif)# exit

Switch(config)# map-list net1011

Switch(config-map-list)# ip 10.1.1.2 atm-vc 1011

Switch(config-map-list)# end

Switch#
