Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
9.4(0.0) Introduced on the FN I/O Aggregator.
9.2(0.0) Introduced on the M I/O Aggregator.
Usage Information
By applying a DCB input policy with PFC enabled, you enable PFC operation on ingress port trac. To achieve
complete lossless handling of trac, also enable PFC on all DCB egress ports or congure 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
Conguration 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 ow control at the same time on an interface.
pfc no-drop queues
Congure the port queues that still function as no-drop queues for lossless trac.
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
2-3. The range is from 0 to 3.
Defaults No lossless queues are congured.
