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.
Dell Networking OS Behavior: A priority group consists of 802.1p priority values that are grouped 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.
Configure all 802.1p priorities in priority groups associated with an ETS output policy. You can assign each
dot1p priority to only one priority group.
By default, all 802.1p priorities are grouped in priority group 0 and 100% of the port bandwidth is assigned to
priority group 0. The complete bandwidth is equally assigned to each priority class so that each class has 12
to 13%.
