Version Description
9.4(0.0) Supported on the FN I/O Aggregator.
9.3(0.0) Introduced on the FC Flex IO module installed in the M I/O
Aggregator.
Usage Information
Use the dcb-map command to configure priority groups with PFC and/or ETS
settings and apply them to Ethernet interfaces.
Use the priority-pgid command to map 802.1p priorities to a priority group.
You can assign each 802.1p priority to only one priority group. A priority group
consists of 802.1p priority values that are grouped together for similar bandwidth
allocation and scheduling, and that share latency and loss requirements. All 802.1p
priorities mapped to the same queue must be in the same priority group.
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.
