Generic Commands
The value given for kilobits-per-second is expressed in kilobits-per-second on a base 10 scale that is
usual for line rate calculations. If a value of 1 is given, the result is 1000 bits per second (as opposed to
a base 2 interpretation that would be 1024 bits per second).
group name — specifies the existing group which specifies the weighted scheduler group this level maps
to.
weight weight — Specifies and integer which specifies the weight of the level within this weighted
scheduler group.
Values
Default
max-rate
Syntax
max-rate pir-rate
max-rate percent percent-rate
no max-rate
Context
config>qos>port-scheduler-policy
Description
This command defines an explicit maximum frame based bandwidth limit for the port scheduler policies
scheduler context. By default, once a scheduler policy is associated with a port , the instance of the scheduler
on the port automatically limit the bandwidth to the lesser of port line rate and a possible egress-rate value
(for Ethernet ports). If a max-rate is defined that is smaller than the port rate, the expressed kilobits-per-
second value is used instead. The max-rate command is another way to sub-rate the port.
The max-rate command may be executed at anytime for an existing port-scheduler-policy. When a new
max-rate is given for a policy, the system evaluates all instances of the policy to see if the configured rate is
smaller than the available port bandwidth. If the rate is smaller and the maximum rate is not currently
overridden on the scheduler instance, the scheduler instance is updated with the new maximum rate value.
The max-rate value defined in the policy may be overridden on each scheduler instance. If the maximum
rate is explicitly defined as an override on a port, the policies max-rate value has no effect.
The no form of this command removes an explicit rate value from the port scheduler policy. Once removed,
all instances of the scheduler policy on egress ports are allowed to run at the available line rate unless the
instance has a max-rate override in place.
Parameters
pir-rate — Specifies the PIR rate.
Values
percent percent-rate — Specifies the percent rate.
