Command Command Mode interface {tengigabitEthernet CONFIGURATION slot/port | fortygigabitEthernet slot} port-number is a port number from 0 to 23. 2 Open a DCB map and enter DCB dcb-map name map configuration mode. INTERFACE 3 Disable PFC. no pfc mode on DCB MAP 4 Return to interface configuration exit mode. DCB MAP 5 Apply the DCB map, created to dcb-map {name } disable the PFC operation, on the interface INTERFACE 6 Configure the port queues that still pfc no-drop queuesqueue-range INTERFACE function as no-drop queues for lossless traffic. For the dot1p- queue assignments. The maximum number of lossless queues globally supported on a port is 2. You cannot configure PFC no-drop queues on an interface on which a DCB map with PFC enabled has been applied, or which is already configured for PFC using the pfc priority command. Range: 0-3. Separate queue values with a comma; specify a priority range with a dash; for example: pfc no-drop queues 1,3 or pfc no-drop queues 2-3 Default: No lossless queues are configured. Applying a DCB Map on a Line Card On the C9010, DCB is supported per-line card. If the traffic handled by a DCB map is transmitted on ports on different line cards, you must manually configure the DCB map on the backplane ports of the C9010 line cards on which the ports reside. • Apply a DCB map with PFC and ETS settings on the backplane ports of C9010 line cards.
