the relevant Dell Networking OS Command Line Reference Guide.
Version Description
9.8(0.0) Introduced on the S3048-ON and S4048-ON.

9.3(0.0) Introduced on the MXL 10/40GbE Switch with the FC Flex IO

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.
NOTE: We do 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.
