Description Use this command to configure the bandwidth for each Priority Group, to associate a weight to a
DWRR scheduler queue, and to enable the PFC.
You can define up to eight additional DWRR Priority Groups with the PGID values in the range of
0-7. Strict Priority Groups take priority in order from the lowest PGID value to the highest PGID
value, for example, a PGID of 15.0 is a higher priority than a PGID of 15.1 and PGID of 15.1 is
higher priority than PGID 15.2.
Use the no priority-group-table pgid command to return the Priority Group to the default values. For
the Strict Priority Group, the PGID is still valid, but the PFC is disabled. For the DWRR Priority Group,
the PGID is no longer valid and is deleted; the PGID can only be deleted when it is not bound to any
Priority-to-Priority Group Table entry.
Usage A PGID value of 15 is a special value, which allows you to configure priorities with no bandwidth
Guidelines limit. The priority groups 15.0-5.7 are pre-defined in the switch.
Examples To define the CEE map and configure the bandwidth with the Priority Group, use the values in
