Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
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.
All 802.1p priorities must be configured 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.
If you configure more than one priority queue as strict priority or more than one priority group
as strict priority, the higher numbered priority queue is given preference when scheduling data
traffic.

Usage
Information
The ETS configuration associated with 802.1p priority traffic in a DCB output policy is used in
DCBX negotiation with ETS peers.
If you disable ETS in an output policy applied to an interface using the
no ets mode on
command, any previously configured QoS settings at the interface or global level take effect. If
