Configuring Layer 3 Terminated Virtual Circuits
A virtual circuit (VC) is a point-to-point connection between two ATM devices. A VC is established for
each ATM end node with which the router communicates. The characteristics of the VC are established
when it is created and include the following for the 4-Port ATM ISE line cards:

Permanent virtual circuits (PVCs) configured on the router remain active until the circuit is removed
from the configuration. All virtual circuit characteristics apply to PVCs. When a PVC is configured, all
configuration options are passed to the 4-Port ATM ISE line card. These PVCs are written to the
nonvolatile RAM (NVRAM) as part of the configuration and are used when the Cisco IOS image is
reloaded.
When you create a PVC, you create a virtual circuit descriptor (VCD) and attach it to the VPI and VCI.
The VCD tells the card which VPI/VCI to use for a particular packet. The 4-Port ATM ISE line card
requires this feature to manage the packets for transmission. The number chosen for the VCD is
independent of the VPI/VCI used.
A permanent virtual path (PVP) is like a bundle of VCs, transporting all cells with a common VPI, rather
than a specific VPI and VCI.
PVCs are created and configured using the pvc command in interface configuration mode. PVPs are
created and configured using the atm pvp command in interface configuration mode.
The syntax of the pvc command is as follows:
pvc [name] vpi/vci
