Service Manual

Repeat the priority-group bandwidth pfc 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.
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.
