Usage Information

By applying a DCB input policy with PFC enabled, you enable PFC operation on ingress port traffic. To achieve complete lossless handling of traffic, also enable PFC on all DCB egress ports or configure the dot1p priority-queue assignment of PFC priorities to lossless queues (refer to 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).

You cannot enable PFC and link-level flow control at the same time on an interface.

NOTE: We do not recommended to use this command as it has been deprecated in the current 9.4(0.0) release. A warning message appears when you try to run this command indicating that you have to use the dcb-map commands in the future.
