Dcb-Policy Input Stack-Unit Stack-Ports All - Dell MXL 10GbE Reference Manual

•
•
In a switch stack, configure all stacked ports with the same PFC configuration.
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.
