Information
A priority group consists of 802.1p priority values that are grouped together for similar bandwidth
allocation and scheduling, and that share the same latency and loss requirements. All 802.1p priorities
mapped to the same queue should be in the same priority group.
All 802.1p priorities should be configured 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
