Advanced Policy QoS Commands
This option is intended for use with children that would benefit from faster than normal startup detection,
typically those of a real-time nature.
When this parameter is not enabled, the system uses the normal sampling interval behavior of both newly
active and currently active children.
The no form of this command is used to restore the sampling interval based offered rate evaluation for
newly active children.
fast-stop
Syntax [no] fast-stop
Context config>qos>adv-config-policy>child-control>offered-measurement
Description
This command is used to enable fast detection of lack of offered rate on a child policer or queue associated
with the policy. Multiple offered rate counter reads may be performed per sampling interval. The system
accumulates these counter values and evaluates the delta at the conclusion of the sampling interval. When
fast-stop is enabled, the system bypasses the sampling interval for any currently active 'fast stop' child that
has a zero offered counter measurement and does an immediate offered rate evaluation using the zero value.
This option is intended for use with children where other children would benefit from faster than normal
inactive detection, typically those of a real-time nature.
When this parameter is not enabled, the system uses the normal sampling interval behavior of both newly
inactive and currently active children.
The no form of this command is used to restore the sampling interval based offered rate evaluation for
newly inactive children.
bandwidth-distribution
Syntax offered-measurement
Context config>qos>adv-config-policy>child-control
Description This command modifies or controls the bandwidth distribution phase of the parent virtual scheduler.
This command edits the parameters that control the child given bandwidth for all policers and queues
associated with the policy.
above-offered-cap
Syntax [no] above-offered-cap {percent percent-of-admin-pir | rate rate-in-kilobits-per-second}
Context config>qos>adv-config-policy>child-control>bandwidth-distribution
Description
This command is used to limit the operationally configured shaping or policing rate on the child associated
with the policy. After the parent virtual scheduler or policer control policy determines the appropriate rate
