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.
