Table of Contents

A priority group consists of 802.1p priority values that are grouped for similar

bandwidth allocation and scheduling, and that share latency and loss requirements.

All 802.1p priorities mapped to the same queue must be in the same priority group.

You must configure 802.1p priorities in priority groups associated with an ETS

output policy. You can assign each dot1p priority to only one priority group.

The maximum number of priority groups supported in ETS output policies on an

interface is equal to the number of data queues (4) on the port. The 802.1p

priorities in a priority group can map to multiple queues.

If you configure more than one priority queue as strict priority or more than one

priority group as strict priority, the higher numbered priority queue is given

preference when scheduling data traffic.

You must fully define the priority-group profile with a PGID and priorities before

mapping it to a QoS policy because the PGID and priorities are unique keys of the

traffic class group (TCG) that define the QoS policy.

You must disable the DCB output policy before changing the PGID or priorities of a

priority group assigned to that DCB output policy.
