Service Manual

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.
priority-group bandwidth pfc
Configure the ETS bandwidth allocation and PFC mode used to manage port traffic in an 802.1p priority
group.
Parameters
priority-group
group-num
Enter the keyword priority-group followed by the
number of an 802.1p priority group. Use the priority-
pgid
command to create the priority groups in a DCB map.
bandwidth
percentage
Enter the keyword bandwidth followed by a bandwidth
percentage allocated to the priority group. The range of
valid values is 1 to 100. The sum of all allocated bandwidth
percentages in priority groups in a DCB map must be 100%.
strict-priority Configure the priority-group traffic to be handled with strict
priority scheduling. Strict-priority traffic is serviced first,
before bandwidth allocated to other priority groups is made
available.
pfc {on | off} Configure whether priority-based flow control is enabled
(on) or disabled (off) for port traffic in the priority group.
Defaults None
