Information
If an error occurs in an ETS output-policy configuration, the configuration is ignored and the scheduler
and bandwidth allocation settings are reset to the ETS default values (all priorities are in the same ETS
priority group and bandwidth is allocated equally to each priority).
If an error occurs when a port receives a peer’s ETS configuration, the port’s configuration is reset to
the previously configured ETS output policy. If no ETS output policy was previously applied, the port
is reset to the default ETS parameters.

History
Usage
Information
dot1p priority traffic on the switch is scheduled to the current queue mapping. dot1p priorities within
the same queue should have the same traffic properties and scheduling method.
ETS-assigned scheduling applies only to data queues, not to control queues.
The configuration of bandwidth allocation and strict-queue scheduling is not supported at the same
time for a priority group. If both are configured, the configured bandwidth allocation will be ignored
for priority-group traffic when you apply the output policy on an interface.
