Defaults Command Modes Command History Usage Information Related Commands none CONFIGURATION Version 8.3.12.0 Version 8.3.16.0 Introduced on the S4810. Introduced on the MXL 10/40GbE Switch IO Module. 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. All 802.1p priorities must 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. • priority-list - configures the 802.1p priorities for an ETS output policy. • set-pgid - configures 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. S4810 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. Parameters group-name ets-policy-name Enter the group name of the 802.1p priority group. The maximum is 32 characters. Enter the ETS policy name. Defaults Command Modes Command History none DCB OUTPUT POLICY Version 8.3.12.0 Version 8.3.16.0 Introduced on the S4810. Introduced on the MXL 10/40GbE Switch IO Module. Usage Information The ETS configuration associated with 802.1p priority traffic in a DCB output policy is used in DCBX negotiation with ETS peers. If you disable ETS in an output policy applied to an interface using the no ets mode on command, any previously configured QoS settings at the interface or global level take effect. If 614
