Usage Information
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.
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.
pfc no-drop queues
Configure the port queues that still function as no-drop queues for lossless traffic.
Syntax
pfc no-drop queues queue-range
To remove the no-drop port queues, use the no pfc no-drop queues command.
Parameters
queue-range Enter the queue range. Separate the queue values with a
comma; specify a priority range with a dash; for example, pfc
no-drop queues 1,3 or pfc no-drop queues 7 or pfc
no-drop queues 0,7
. The range is from 0 to 3.
Defaults No lossless queues are configured.
