Mapping a Protocol Address to a PVC Using Static Map Lists
Displaying the Map-List Interface Configuration
To show the map-list interface configuration, use the following EXEC command:
Example
The following example displays the map-list configuration at interface ATM 0:
Switch# show atm map
Map list yyy : PERMANENT
ip 1.1.1.2 maps to VPI=0 VCI=200
Configuring an SVC-Based Map List
This section describes how to map an SVC to an NSAP address. This is a required task if you are
configuring an SVC.
You enter mapping commands as groups. You first create a map list and then associate it with an
interface. Perform the following steps, beginning in global configuration mode:
You can create multiple map lists, but only one map list can be associated with an interface. Different
map lists can be associated with different interfaces.
Command Purpose
show atm map Shows the ATM interface map-list
configuration.
Command Purpose
Step 1
Switch(config)# interface atm
card/subcard/port[.subinterface#]
Switch(config-if)#
Specifies an ATM interface and enters interface
configuration mode.
Step 2
Switch(config-if)# ip address ip-address mask Enters the IP address and subnet mask associated
with this interface.
Step 3
Switch(config-if)# atm nsap-address
nsap-address
Configures the interface NSAP address.
Step 4
Switch(config-if)# map-group name Enters the map-group name associated with this
PVC.
Step 5
Switch(config-if)# exit
Switch(config)#
Exits interface configuration mode.
Step 6
Switch(config)# map-list name
Switch(config-map-list)#
Creates a map list by naming it, and enters
map-list configuration mode.
Step 7
Switch(config-map-list)# ip ip-address
{atm-nsap address | atm-vc vci} [aal5mux
encapsulation] [broadcast pseudo-broadcast]
[class class-name]
