Introduced on MXL 10/40GbE Switch IO Module Usage Information A priority group consists of 802.1p priority values that are grouped together for similar bandwidth allocation and scheduling, and that share the same latency and loss requirements. All 802.1p priorities mapped to the same queue should be in the same priority group. All 802.1p priorities should be configured in priority groups associated with an ETS output policy. You can assign each dot1p priority to only one priority group. The maximum number of priority groups supported in ETS output policies on an interface is equal to the number of data queues (4) on the port. The 802.1p priorities in a priority group can map to multiple queues. If you configure more than one priority queue as strict priority or more than one priority group as strict priority, the higher numbered priority queue is given preference when scheduling data traffic Related Commands priority-list set-pgid Configure the 802.1p priorities for an ETS output policy. Configure the priority-group. priority-group qos-policy Associate the 802.1p priority traffic in a priority group with the ETS configuration in a QoS output policy. Syntax priority-group group-name qos-policy ets-policy-name To remove the 802.1p priority group, use the no priority-group qos-policy command. 482 | Data Center Bridging
