command.

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— configures the ETS bandwidth allocation and the PFC setting
used to manage the port traffic in an 802.1p priority group.
priority-group bandwidth pfc
Configure the ETS bandwidth allocation and PFC mode used to manage port traffic in an 802.1p priority group.
S5000
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
share latency and loss requirements. All 802.1p priorities mapped to the same queue must be in
the same priority group.
