Command History
This guide is platform-specic. For command information about other platforms, see the relevant Dell
Networking OS Command Line Reference Guide.
Version Description
9.7(0.0) Introduced on the S6000-ON.
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 trac. To
achieve complete lossless handling of trac, also enable PFC on all DCB egress ports or congure 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
Conguration 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.
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.
priority-group bandwidth pfc
Congure the ETS bandwidth allocation and PFC mode used to manage port trac in an 802.1p priority group.
