priority group. The range 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.

Usage Information
Use this command to configure PFC and ETS traffic handling for each
priority group in a DCB map.
You can enable PFC on a maximum of two priority queues.
If you configure more than one priority group as strict priority, the
higher numbered priority queue is given preference when
scheduling data traffic.
If a priority group does not use its allocated bandwidth, the unused
bandwidth is made available to other priority groups.
By default, equal bandwidth is assigned to each dot1p priority in a
priority group.
Use the bandwidth parameter to configure the bandwidth
percentage assigned to a priority group. The sum of the bandwidth
allocated to all priority groups in a DCB map must be 100% of the
bandwidth on the link.
You must allocate at least 1% of the total port bandwidth to each
priority group.
