Service Manual

Version 8.3.16.0 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.
You can only associate output QoS policy profiles with the priority groups in the
DCB output profile context; output QoS policy profiles are not permitted on output
policy-maps.
WRED, ECN, rate shaping, and rate limiting are not supported in output policies
because DCBx does not negotiate these parameters with peer devices. You can
apply a QoS output policy with WRED and/or rate shaping on a DCBx CIN-enabled
interface.
If you enable the scheduler command for a QoS ETS output policy, no
bandwidth percentage is assigned to the policy.

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 range: strict: strict-priority
traffic is serviced before any other queued traffic.
Defaults Weighted Elastic Round Robin (WERR) scheduling is used to queue priority traffic.
