QoS Queue Group Template Command Reference
Parameters add bytes — Specifies an number of bytes to add as the offset amount.
subtract bytes — Specifies an number of bytes to add as the offset amount.

Description
This command defines an optional parent scheduler that further governs the available bandwidth given
the queue aside from the queue's PIR setting. When multiple schedulers and/or queues share a child
status with the parent scheduler, the weight or level parameters define how this queue contends with
the other children for the parent's bandwidth.
The no form of the command removes a child association with a parent scheduler. If a parent
association does not currently exist, the command has no effect and returns without an error. Once a
parent association has been removed, the former child queue attempts to operate based on its
configured rate parameter. Removing the parent association on the queue within the policy takes effect
immediately on all queues using the SAP egress QoS policy.
Parameters
root — Selects the root level arbiter for the parent to the child.
arbiter-name — Specifies an arbiter for the parent to the child.
weight-within-level — weight defines the relative weight of this queue in comparison to other

Default None. Each parental association must be explicitly defined.
child schedulers and queues while vying for bandwidth on the parent scheduler-name. Any
queues or schedulers defined as weighted receive no parental bandwidth until all strict queues
and schedulers on the parent have reached their maximum bandwidth or are idle. In this
manner, weighted children are considered to be the lowest priority.
