Description
This command overrides the max-rate parameter found in the port-scheduler-policy associated with the
port. When a max-rate is defined at the port or channel level, the port scheduler policies max-rate parameter
is ignored.
The egress-scheduler-override max-rate command supports a parameter that allows the override command
to restore the default of not having a rate limit on the port scheduler. This is helpful when the port scheduler
policy has an explicit maximum rate defined and it is desirable to remove this limit at the port instance.
The no form of this command removes the maximum rate override from the egress port or channels port
scheduler context. Once removed, the max-rate parameter from the port scheduler policy associated with the
port or channel will be used by the local scheduler context.
Parameters
rate — Specifies the explicit maximum frame based bandwidth limit. This value overrides the QoS
scheduler policy rate.
Values

Description
This command enables the provisioning of an existing port-scheduler-policy to a port or channel.
The egress-scheduler-override node allows for the definition of the scheduler overrides for a specific port or
channel.
When a port scheduler is active on a port or channel, all queues and intermediate service schedulers on the
port are subject to receiving bandwidth from the scheduler. Any queues or schedulers with port-parent
associations are mapped to the appropriate port priority levels based on the port-parent command
parameters. Any queues or schedulers that do not have a port-parent or valid intermediate scheduler parent
defined are treated as orphaned and are handled based on the port scheduler policies default or explicit
orphan behavior.
The port scheduler maximum rate and priority level rate parameters may be overridden to allow unique
values separate from the port-scheduler-policy-name attached to the port or channel. Use the egress-
scheduler-override command to specify the port or channel specific scheduling parameters.
The command used to associate an egress scheduler policy on the port is overloaded for HSMDA. HSMDA
policies should be associated with HSMDA ports.
