Configures the internal priority based on classification in the range 0 to 7.
priority-PG-map
Specifies the internal priority-to-PG mapping. The range is 0 to 3.
Modes Global configuration mode
Usage Guidelines The no form of this command restores the default priority-to-PG map.
You must configure the priority-flow-control enable command to enable PFC globally before you
configure priority-to-PG mapping.
The default value of priority-to-PG maps is as follows:
• QoS internal priority 0 is mapped to PG 0
• QoS internal priority 1 is mapped to PG 0
• QoS internal priority 2 is mapped to PG 1
• QoS internal priority 3 is mapped to PG 1
• QoS internal priority 4 is mapped to PG 1
• QoS internal priority 5 is mapped to PG 2
• QoS internal priority 6 is mapped to PG 2
• QoS internal priority 7 is mapped to PG 2
You can map QoS internal priority 7 to PG 3. You can also map any other priority to PG 3 ifit meets
these requirements:
• Lower priorities mapped to lower PGs.
• PGs are configured in ascending order.
• Multiple priorities in a single PG must be consecutive.
Priority-to-pg mapping is not configurable in other modes. Symmetrical and Asymmetrical 802.3x Flow
Control modes have their own default priority-to-PG mapping.
You must configure PGs in ascending order, 0-3. You can configure a higher-order PG only if all the
lower-order PGs have some mapped priorities.
Examples The following example shows how to configure a priority-to-PG map:
Device(config)# priority-flow-control enable
Device(config)# qos priority-to-pg qosp0 0 qosp1 1 qosp2 1 qosp3 1 qosp4 2 qosp5 2
qosp6 2 qosp7 2
The following example shows how to restore the default priority-to-PG map:
Device(config)# no qos priority-to-pg qosp0 0 qosp1 1 qosp2 1 qosp3 1 qosp4 2 qosp5 2
qosp6 2 qosp7 2
