Owners Manual

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.
