QoS Scheduler Policies
Quality of Service Guide 579
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 or channel, 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 or channel 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 1 to 3200000000, max, in Kbps
percent percent-rate — Specifies the percent rate.
Values 0.01 to 100.00
monitor-threshold
Syntax monitor-threshold percent
no monitor-threshold
Context config>qos>port-scheduler-policy
Description This command defines the congestion monitoring threshold for the desired monitoring entity under the
port-scheduler for per aggregate port-scheduler rate, per individual level, and per group that is
aggregating multiple levels.
The congestion threshold is specified in percentages of the configured PIR rate for the entity for which
congestion monitoring is desired. For example, if the configured PIR rate for level 1 is 100,000 Kbps,
and the monitoring threshold is set to 90%, then an event where the offered rate is >90,000 Kbps will
be recorded. This event is shown as part of the cumulative count of congestion threshold exceeds since
the last clearing of the counters.
The no form of this command removes the congestion monitoring threshold.
Default no monitor-threshold
Parameters 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
