priority-group-table
Configures the bandwidth for each Priority Group.
Synopsis priority-group-table pgid [weight weight] [pfc]
no priority-group-table pgid
Operands pgid Specifies the Priority Group ID (PGID) assigned to a Priority Group. The range
of valid values is from 0 through 7, and the range from 15.0 through 15.7 is
for eight reserved strict priority PGIDs.
weight weight Maps a weight to a Deficit Weighted Round Robin (DWRR) scheduler queue.
This parameter is only valid for the DWRR Priority Group. The sum of all DWRR
Priority Group weight values must equal 100 percent. The range of valid
values is from 1 through 100.
pfc Enables the Priority-based Flow Control (PFC) for each priority that gets
mapped to the Priority Group.
Defaults There is no default value for the weight. The PFC is disabled.

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 from
0 through 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 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the PGID is no longer valid and is deleted; the PGID can only be deleted when it is not bound to any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
Guidelines
A PGID value of 15 is a special value, which allows you to configure priorities with no bandwidth
limit. The Strict Priority Groups 15.0 through 15.7 are predefined in the switch.
Examples To define the CEE map and configure the bandwidth with the Priority Group, use the values in
Table 6.
