Creating an ETS Priority Group
An ETS priority group specifies the range of 802.1p priority traffic to which a QoS output policy with ETS
settings is applied on an egress interface.
1 Configure a DCB Map.
CONFIGURATION mode
dcb-map dcb-map-name
The dcb-map-name variable can have a maximum of 32 characters.
2 Create an ETS priority group.
CONFIGURATION mode
priority-group group-num {bandwidth bandwidth | strict-priority} pfc off
The range for priority group is from 0 to 7.
Set the bandwidth in percentage. The percentage range is from 1 to 100% in units of 1%.
Committed and peak bandwidth is in megabits per second. The range is from 0 to 40000.
Committed and peak burst size is in kilobytes. Default is 50. The range is from 0 to 10000.
3 Configure the 802.1p priorities for the traffic on which you want to apply an ETS output policy.
PRIORITY-GROUP mode
priority-list value
The range is from 0 to 7.
The default is none.
Separate priority values with a comma. Specify a priority range with a dash. For example, priority-list
3,5-7.
4 Exit priority-group configuration mode.
PRIORITY-GROUP mode
exit
5 Repeat Steps 1 to 4 to configure all remaining dot1p priorities in an ETS priority group.
6 Specify the dot1p priority-to-priority group mapping for each priority.
priority-pgid dot1p0_group_num dot1p1_group_num ...dot1p7_group_num
Priority group range is from 0 to 7. All priorities that map to the same queue must be in the same priority
group.
Leave a space between each priority group number. For example: priority-pgid 0 0 0 1 2 4 4 4 in which
priority group 0 maps to dot1p priorities 0, 1, and 2; priority group 1 maps to dot1p priority 3; priority
group 2 maps to dot1p priority 4; priority group 4 maps to dot1p priorities 5, 6, and 7.
