Version Description
9.4(0.0) Supported on the FN I/O Aggregator.
9.2(0.0) Introduced on the M I/O Aggregator.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage
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.

Commands
● scheduler — schedules the priority traffic in port queues.
● bandwidth-percentage — bandwidth percentage allocated to the priority traffic in port queues.
scheduler
Configure the method used to schedule priority traffic in port queues.
Syntax
scheduler value
To remove the configured priority schedule, use the no scheduler command.
Parameters
value Enter schedule priority value. The valid values are:
● strict: strict-priority traffic is serviced before any other queued traffic.
● werr: weighted elastic round robin (werr) provides low-latency scheduling for
priority traffic on port queues.
Defaults Weighted elastic round robin (WERR) scheduling is used to queue priority traffic.
Command Modes POLICY-MAP-OUT-ETS
Supported Modes Programmable-Mux (PMUX)

9.4(0.0) Supported on the FN I/O Aggregator.

8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
dot1p priority traffic on the switch is scheduled to the current queue mapping. dot1p priorities within the
same queue must 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 you configure both, the configured bandwidth allocation is ignored for priority-
group traffic when you apply the output policy on an interface.
