QoS Scheduler Policy Command Reference
578 Quality of Service Guide
percent-rate pir-percent — Specifies the percent bandwidth limits allocated to priority-level.
Values 0.01 to 100.00 | max (Kilobits per second)
cir cir — The cir specified limits the total bandwidth allocated in the within-cir distribution pass
to priority-level. When cir is not specified, all the available port or channel bandwidth may
be allocated to the specified priority level during the within-cir pass.
Values 0 to 3200000000 | max (Kilobits per second)
The value given for kilobits-per-second is expressed in kilobits-per-second on a base 10 scale
as 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).
percent-cir cir-percent — Specifies the percent bandwidth limits allocated to priority-level.
Values 0.01 to 100.00 | max (Kilobits 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 1 to 100
Default 1
monitor-threshold percent — Specifies the percent of the configured rate. If the offered rate
exceeds the configured threshold, a counter monitoring the threshold will be increased.
Values 0 to 100
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 or channel, the
instance of the scheduler on the port automatically limit the bandwidth to the lesser of port or channel
line rate and a possible egress-rate value (for Ethernet ports). If a max-rate is defined that is smaller
than the port or channel rate, the expressed kilobits-per-second value is used instead. The max-rate
command is another way to sub-rate the port or channel. This command can be used on channels only
on the 7450 ESS and 7750 SR.
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 or channel 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.
