54.3.3 PVC Delete Command

Syntax:

ras> shdsl pvc delete

where

This command deletes the specified PVC channel.

54.4 Priority-based PVCs

This feature is available in STU-C mode only.
A PPVC (Priority-based PVC) allows you to give different priorities to PVCs that are
members of the same VLAN.
The IES-708-22A uses eight priority queues (also called levels) for the member PVCs. The
system maps frames with certain IEEE 802.1p priorities to a PVC with a particular priority
queue. See

Chapter 57 on page 387

for the factory default mapping.

Use these commands to configure PPVCs and add and remove member PVCs.
