Dcb-Policy Input Stack-Unit Stack-Ports All - Dell Force10 S4810P Reference Manual

A DCB input policy for PFC applied to an interface may become invalid if the dot1p-queue
mapping is reconfigured. 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.
