Interface Configuration Examples

Interface Configuration Examples
This section provides sample procedures for creating ATM subinterfaces, permanent virtual circuits
(PVCs), and virtual circuit (VC) classes, and procedures for enabling Integrated Local Management
Interface (ILMI).
Creating a Subinterface
Use the following procedure to create a subinterface.
Separate the ATM interface into subinterfaces using the interface command. You can create either a
Step 1
point-to-point or multipoint subinterface.
In the following example, multipoint subinterface number 1 is created on port 0 of the 4-Port
OC-3/STM-1 ATM line card in slot 2.
Router(config)# interface atm 2/0/0.1 multipoint
Router(config-subif)#
Assign an IP address and subnet mask to the created interface using the ip address configuration
Step 2
subcommand, as shown in the following example:
Router(config-subif)# ip address 172.27.48.209 255.255.0.0
Router(config-subif)#
You have created ATM subinterface 2/0/0.1. To configure or modify this interface, use the following
command:
Router(config)# interface atm 2/0/0.1
Router(config-subif)#
Creating a PVC
You can create multiple PVCs on a 4-Port OC-3/STM-1 ATM line card interface. You can create PVCs
on the main interface or on a subinterface.
To create a PVC
Step 1 Enter interface or subinterface configuration mode.
Use the pvc command to specify a virtual path identifier (VPI) value between 0 and 255 and a virtual
channel identifier (VCI) value between 0 and 65535. The following example shows how to create a PVC
with a VPI value of 0 and VCI value of 100 on a subinterface.
Router(config-subif)# pvc 0/100
Router(config-if-atm-vc)#
Use the protocol ip configuration subcommand to assign a peer IP address to the PVC, as shown in the
Step 2
following example:
Router(config-if-atm-vc)# protocol ip 172.16.32.49
Router(config-if-atm-vc)#
