QoS Scheduler Policies
Quality of Service Guide 569
If the provided scheduler-name is invalid according to the criteria below, a name syntax error will
occur, the command will not execute, and the CLI context will not change.
Parameters scheduler-name — The name of the scheduler.
Values Valid names consist of any string up to 32 characters long
composed of printable, 7-bit ASCII characters. If the string
contains special characters (#, $, spaces, etc.), the entire string
must be enclosed within double quotes.
Default None. Each scheduler must be explicitly created.
create — This optional keyword explicitly specifies that it is acceptable to create a scheduler with
the given scheduler-name. If the create keyword is omitted, scheduler-name is not created
when the system environment variable create is set to true. This safeguard is meant to avoid
accidental creation of system objects (such as schedulers) while attempting to edit an object
with a mistyped name or ID. The keyword has no effect when the object already exists.
limit-unused-bandwidth
Syntax [no] limit-unused-bandwidth
Context config>qos>scheduler-policy>tier>scheduler
Description This command is used to enable (or disable) aggregate rate overrun protection on the agg-rate context.
parent
Syntax parent scheduler-name [weight weight] [level level] [cir-weight cir-weight] [cir-level cir-
level]
no parent
Context config>qos>scheduler-policy>tier>scheduler
Description This command defines an optional parent scheduler that is higher up the policy hierarchy. Only
schedulers in tier levels 2 and 3 can have a parental association. When multiple schedulers and/or
queues share a child status with the scheduler on the parent, the weight or strict parameters define how
this scheduler contends with the other children for the parent’s bandwidth. The parent scheduler can
be removed or changed at anytime and is immediately reflected on the schedulers created by
association of this scheduler policy.
When a parent scheduler is defined without specifying weight or strict parameters, the default
bandwidth access method is weight with a value of 1.
