PFC and ETS settings are not pre-configured on Ethernet ports. You must use the dcb-map command to configure different groups of 802.1p priorities with PFC and ETS settings. Using the priority-pgid command, you assign each 802.1p priority to one priority group. 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. For example, the priority-pgid 0 0 0 1 2 4 4 4 command creates the following groups of 802.1p priority traffic: • Priority group 0 contains traffic with dot1p priorities 0, 1, and 2. • Priority group 1 contains traffic with dot1p priority 3. • Priority group 2 contains traffic with dot1p priority 4. • Priority group 4 contains traffic with dot1p priority 5, 6, and 7. To remove a priority-pgid configuration from a DCB map, enter the no priority-pgid command. dcb-map -Creates a DCB map to configure PFC and ETS parameters and applies the PFC and ETS settings on Ethernet ports. priority-group bandwidth pfc- Configures the ETS bandwidth allocation and the PFC setting used to manage the port traffic in an 802.1p priority group. show dcb Displays the data center bridging status, the number of PFC-enabled ports, and the number of PFCenabled queues. Syntax show dcb [stack-unit unit-number] Parameters unit number Enter the DCB unit number. The range is from 0 to 5. 306
