To achieve complete lossless handling of traffic, you must also enable PFC on all DCB egress ports or configure the dot1p priority-queue assignment of PFC priorities to lossless queues (see pfc no-drop queues). To disable PFC operation on an interface, enter the no pfc mode on command in DCB input policy configuration mode. PFC is enabled and disabled as global DCB operation is enabled (dcb-enable) or disabled (no dcb-enable). PFC and link-level flow control cannot be enabled at the same time on an interface. Related Commands dcb-input Create a DCB input policy. pfc no-drop queues Configure the port queues that will still function as no-drop queues for lossless traffic. Syntax pfc no-drop queues queue-range To remove the no-drop port queues, use the no pfc no-drop queues command. Parameters queue-range Enter the queue range. Separate the 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. Range: 0 to 3. Defaults No lossless queues are configured.
