Configures

Creates an ATM PVC

Default

None

Description

This command creates an ATM Permanent Virtual Circuit (PVC). On recent versions of IOS, it’s preferable to use the pvc command, if available. ATM commands are highly hardware-dependent, so the commands available on any particular router vary. For more information on creating PVCs, consult Chapter 6.

vcd

A Virtual Circuit Descriptor, which is a unique number used to identify this particular VPI/VCI pair on the router.

vpi

The Virtual Path Identifier of the PVC. This identifier is unique only to the interface. The value can be from 0 to 255.

vci

The Virtual Channel Identifier of the PVC, which is a value from 0 to 1023. 0 to 31 are typically reserved for specific kinds of management traffic. vpi and vci may not both be 0.

encap

The type of encapsulation used on the line. The encapsulation may be aal5mux (a MUX-type virtual connection), aal5snap (the only encapsulation supported for Inverse ARP), aal1 (used for streaming video), aal5voice (used for voice traffic), ilmi, and qsaal.

peak

Optional, but required for voice circuits. The maximum capacity of the virtual circuit in kbps. peak ranges from 56 to 10000. The default is the link’s maximum capacity.

avg

Optional, but required for voice circuits. The average rate at which ...
