NOTE: Please note that Dell Networking does not recommended to use this
command as it has been deprecated in the current 9.4(0.0) release. A warning
message appears when you try to run this command indicating that you have
to use the dcb-map commands in the future.
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.
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%.
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.
Configure whether priority-based flow control is enabled
(on) or disabled (off) for port traffic in the priority group.
Introduced on the S4810, S6000 platforms.
