Usage Information
NOTE: Please note that Dell Networking does not recommended to use this command as it has

this command indicating that you have to use the dcb-map commands in the future.
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 congure 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 congure 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 trac.
You must fully dene the priority-group prole with a PGID and priorities before mapping it to a QoS policy
because the PGID and priorities are unique keys of the trac class group (TCG) that dene 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.
