NOTE: The IEEE 802.1Qaz, CEE, and CIN versions of ETS are supported.Creating an ETS Priority GroupAn ETS priority group specifies the range of 802.1p priority traffic to which a QoS output policy with ETS settings is applied on anegress interface.1. Configure a DCB Map.CONFIGURATION modedcb-map dcb-map-nameThe dcb-map-name variable can have a maximum of 32 characters.2. Create an ETS priority group.CONFIGURATION modepriority-group group-num {bandwidth bandwidth | strict-priority} pfc offThe 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 modepriority-list valueThe 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 modeexit5. 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_numPriority 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 todot1p priorities 0, 1, and 2; priority group 1 maps to dot1p priority 3; priority group 2 maps to dot1p priority 4; priority group 4maps 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 allocationand scheduling, and that share latency and loss requirements. All 802.1p priorities mapped to the same queue must be in the samepriority group.Configure all 802.1p priorities in priority groups associated with an ETS output policy. You can assign each dot1p priority to only onepriority group.Data Center Bridging (DCB) 255
