CLI Guide

This method of configuration provides an easy and flexible technique to
accommodate both administratively-configured and peer-configured priorities.
Example
Dell (conf-dcb-buffer-thr)#priority 0 buffer-size 52 pause-
threshold 16 resume-offset 10 shared-threshold-weight 7
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.
