To remove the congured priority schedule, use the no scheduler command.
Parameters
value Enter schedule priority value. The valid values are:
• strict: strict-priority trac is serviced before any other queued trac.
• werr: weighted elastic round robin (werr) provides low-latency scheduling for
priority trac on port queues.
Defaults Weighted elastic round robin (WERR) scheduling is used to queue priority trac.

8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
dot1p priority trac on the switch is scheduled to the current queue mapping. dot1p priorities within the
same queue must have the same trac properties and scheduling method.
ETS-assigned scheduling applies only to data queues, not to control queues.
The conguration of bandwidth allocation and strict-queue scheduling is not supported at the same time for
a priority group. If you congure both, the congured bandwidth allocation is ignored for priority-group
trac when you apply the output policy on an interface.
