Usage Information By default:
• All 802.1p priorities are grouped in priority group 0.
• 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%.
priority-group
To use with an ETS output policy, create an ETS priority group.

8.3.16.0 Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
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.
You must configure 802.1p priorities in priority groups associated with an ETS output policy. You can
assign each dot1p priority to only one priority group.
The maximum number of priority groups supported in ETS output policies on an interface is equal to the
number of data queues (4) on the port. The 802.1p priorities in a priority group can map to multiple
queues.
