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
History
Version 9.3.0.0 Introduced on the FC Flex IO module installed in the M I/O
Aggregator and MXL 10/40GbE Switch.
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.

Commands
• qos-policy-output ets — configures the ETS bandwidth allocation.
