When you apply an input policy to an interface, an error message is displayed if:

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.

Syntax
dcb-policy input stack-unit {all | stack-unit-id} stack-ports

Introduced on the M I/O Aggregator. This command is
supported in Programmable-Mux (PMUX) mode only.
Introduced on the MXL 10/40GbE Switch IO Module.
You can enable link-level flow control on the interface. To delete the input
policy, first disable link-level flow control. PFC is then automatically enabled on
the interface because an interface is by default PFC-enabled.
PFC still allows you to configure lossless queues on a port to ensure no-drop
handling of lossless traffic.
The PFC dot1p priorities result in more than two lossless port queues globally
on the switch.
You already enabled link-level flow control. PFC and link-level flow control
cannot be enabled at the same time on an interface.
NOTE: Please note that Dell Networking does 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.
— creates a DCB input policy.
