Chapter 16 Configuring Tag Switching and MPLS
To connect the source and destination switch VP tunnels, proceed to the next section,
VP

Displaying the VP Tunnel Configuration

To display the VP tunnel configuration, use the following EXEC command:
Command
show atm vp
The following example shows PVP 51 configured on ATM interface 0/1/1:
Switch# show atm vp
Interface
ATM0/1/1

Connecting the VP Tunnels

To complete the VP tunnel, you must configure the ATM ports on the intermediate switch to designate
where to send packets coming from the source switch and going to the destination switch.
To connect the permanent virtual path (PVP), perform the following steps, beginning in interface
configuration mode:
Command
Step 1 Switch(config)# interface atm card/subcard/port
Switch(config-if)#
Step 2 Switch(config-if)# atm pvp vpi interface atm
card/subcard/port vpi-B
