History
Version 9.3(0.0) Introduced on the FC Flex IO module installed in the MXL
10/40GbE Switch module platform.
Usage
Information
PFC and ETS settings are not pre-configured on Ethernet ports. You must use the
dcb-map
command to configure different groups of 802.1p priorities with PFC and
ETS settings.
Using the
priority-pgid
command, you assign each 802.1p priority to 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. For example, the
priority-pgid 0 0 0 1 2 4 4 4
command creates the following groups of 802.1p priority traffic:
• Priority group 0 contains traffic with dot1p priorities 0, 1, and 2.
• Priority group 1 contains traffic with dot1p priority 3.
• Priority group 2 contains traffic with dot1p priority 4.
• Priority group 4 contains traffic with dot1p priority 5, 6, and 7.
To remove a priority-pgid configuration from a DCB map, enter the
no
priority-pgid
command.

Syntax
priority-group group-num {bandwidth percentage | strict-
priority} pfc {on | off}
Parameters
priority-group
group-num
Enter the keyword
priority-group
followed by the
number of an 802.1p priority group. Use the
priority-
pgid
command to create the priority groups in a DCB map.
bandwidth
percentage
Enter the keyword
bandwidth
followed by a bandwidth
percentage allocated to the priority group. The range of valid
values is 1 to 100. The sum of all allocated bandwidth
percentages in priority groups in a DCB map must be 100%.
