Reference Guide

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.
To remove a priority-group configuration in a DCB map, enter the no priority-
group bandwidth pfc command.
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.
