Priority Group Feature

PG (ETS) allocates link bandwidth based on the priority group setting on a link. Different traffic types might have different network bandwidth requirements. With a PGID group identifier, one or more priorities can be grouped together for the purpose of bandwidth allocation. The number of priority groups that can be supported cannot exceed the number of traffic classes supported.

Before you configure the PG, you must identify the priority to the priority group mapping based on the network traffic types and the bandwidth requirement for each PG. In some deployment environments, a priority group can be configured as an unrestricted group. This unrestricted group does not need its bandwidth allocation, and strict priority scheduling is applied to this group.

The PG feature is an asymmetric parameter exchange feature. This means that the desired PG configuration for the peer does not have to match the local PG configuration.
