Command
History
Version 9.3(0.0) Introduced on the MXL 10/40GbE Switch with the FC Flex IO
module.
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: 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.
