Service Manual

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

Version Description
9.8(1.0) Introduced on the Z9100–ON.
9.8(0.0) Introduced on the S3048-ON and S4048-ON.
9.7(0.0) Introduced on the S6000-ON and Z9500.
9.3(0.0) Introduced on the S4810, S6000 platforms.
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 share latency and loss requirements. All 802.1p priorities mapped
to the same queue must be in the same priority group.
