13.8 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. The following table gives the factory default mapping.
