Reference Guide
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.

Commands
• priority-list — configures the 802.1p priorities for an ETS output policy.
• set-pgid — configures the priority-group.
priority-group bandwidth pfc
Configure the ETS bandwidth allocation and PFC mode used to manage port traffic in an 802.1p priority
group.

Syntax
priority-group group-num {bandwidth percentage| strict-
priority} pfc {on | off}
Parameters
priority-group
group-num
Enter the keyword priority-group followed by the
number of an 802.1p priority group. Use the
priority-
pgid command to create the priority groups in a DCB map.
bandwidth
percentage
Enter the keyword bandwidth followed by a bandwidth
percentage allocated to the priority group. The range of valid
values is 1 to 100. The sum of all allocated bandwidth
percentages in priority groups in a DCB map must be 100%.
strict-priority Configure the priority-group traffic to be handled with strict
priority scheduling. Strict-priority traffic is serviced first,
before bandwidth allocated to other priority groups is made
available.
pfc {on | off} Configure whether priority-based flow control is enabled
(on) or disabled (off) for port traffic in the priority group.
Defaults None
