Command Line Reference Guide

Usage
Information
Use the pfc priority command to configure PFC operation on an Ethernet interface for
specified CoS traffic without using a DCB map in a network topology that uses the default ETS
setting (assigns equal bandwidth to each 802.1p priority).
The maximum number of lossless queues supported per port is two. If you reconfigure the
lossless queues for no-drop priorities in a DCB map and reapply the map to the interface,
traffic may be interrupted due to an interface flap (going down and coming up).
The maximum number of lossless queues supported per port is two.
A PFC peer must support the configured priority traffic (as detected by DCBx) to apply PFC.

Commands
dcb-map — creates a DCB map to configure PFC and ETS parameters and applies the PFC and
ETS settings on Ethernet ports.
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, 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

Usage
Information
Use the dcb-map command to configure priority groups with PFC and/or ETS settings and
apply them to Ethernet interfaces.
Use the priority-pgid command to map 802.1p priorities to a priority group. You can
assign each 802.1p priority to only one priority group. A priority group consists of 802.1p priority
values that are grouped together for similar bandwidth allocation and scheduling, and that
