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.
