Addendum
A DCB input policy for PFC applied to an interface may become invalid if you
reconfigure the dot1p-queue mapping. This situation occurs when the new dot1p-
queue assignment exceeds the maximum number (2) of lossless queues supported
globally on the switch. In this case, all PFC configurations received from PFC-
enabled peers are removed and resynchronized with the peer devices.
Traffic may be interrupted when you reconfigure PFC no-drop priorities in an input
policy or reapply the policy to an interface.

dcb-policy input stack-unit stack-unit-id command overwrites any
previous
dcb-policy input stack-unit all configuration.
