priority-group bandwidth pfc— Configures the ETS bandwidth allocation and the
PFC setting used to manage the port traffic in an 802.1p priority group.
pfc mode on
Enable the PFC configuration on the port so that the priorities are included in DCBX negotiation with peer
PFC devices.

History
Version 9.3(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 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.
priority-group bandwidth pfc
Configure the ETS bandwidth allocation and PFC mode used to manage port traffic in an 802.1p priority
group.

Syntax
priority-group group-num {bandwidth percentage| strict-
priority} pfc {on | off}
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,
