Users Guide

If you enable the scheduler command for a QoS ETS output policy, no bandwidth percentage is assigned
to the policy.
Related Commands
• scheduler — schedule the priority trac in port queues.
• bandwidth-percentage — bandwidth percentage allocated to the priority trac in port queues.
scheduler
Congure the method used to schedule priority trac in port queues.
Syntax
scheduler value
To remove the congured priority schedule, use the no scheduler command.
Parameters
value Enter schedule priority value. The range: strict: strict-priority trac is serviced
before any other queued trac.
Defaults Weighted Elastic Round Robin (WERR) scheduling is used to queue priority trac.
Command Modes POLICY-MAP-OUT-ETS

Version Description
8.3.19.0 Introduced on the S4820T.
8.3.12.0 Introduced on the S4810.
8.3.16.0 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.
If you enable this command for a QoS ETS output policy, no bandwidth percentage is assigned to the policy.

show interface ets
Displays the ETS conguration applied to egress trac on an interface, including priority groups with priorities and bandwidth
allocation.
Syntax
