Priority-Group Bandwidth Pfc - Dell S6000 Reference Manual

Usage
PFC and ETS settings are not pre-configured on Ethernet ports. You must use the
Information
dcb-map command to configure different groups of 802.1p priorities with PFC and
ETS settings.
Using the priority-pgid command, you assign each 802.1p priority to one
priority group. A priority group consists of 802.1p priority values that are grouped
together for similar bandwidth allocation and scheduling, and that share latency
and loss requirements. All 802.1p priorities mapped to the same queue must be in
the same priority group. For example, the priority-pgid 0 0 0 1 2 4 4 4
command creates the following groups of 802.1p priority traffic:
•
•
•
•
To remove a priority-pgid configuration from a DCB map, enter the no
priority-pgid command.

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
bandwidth
percentage
strict-priority
pfc {on | off}
Defaults None
Data Center Bridging (DCB)
Priority group 0 contains traffic with dot1p priorities 0, 1, and 2.
Priority group 1 contains traffic with dot1p priority 3.
Priority group 2 contains traffic with dot1p priority 4.
Priority group 4 contains traffic with dot1p priority 5, 6, and 7.
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.
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%.
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.
Configure whether priority-based flow control is enabled
(on) or disabled (off) for port traffic in the priority group.
