Configuring Tag Switching
To connect the source and destination switch VP tunnels, proceed to the next section, “Connecting the
VP Tunnels.”
Displaying the VP Tunnel Configuration
To display the VP tunnel configuration, use the following EXEC command:
The following example shows PVP 51 configured on ATM interface 0/1/1:
Switch# show atm vp
Interface VPI Type X-Interface X-VPI Status
ATM0/1/1 51 PVP TUNNEL
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:
Figure 16-3 shows an example configuration on an intermediate switch.
