local parent or port parent association can be removed at anytime by using the no version of the
appropriate parent command. A scheduler in tier 1 can only be associated with a port parent and
that port parent definition can be added or removed at anytime.

Network Queue Parent Scheduler

Network queues support port scheduler parent priority-level associations. Using a port scheduler
policy definition and mapping network queues to a port parent priority level, HQoS functionality
is supported providing eight levels of strict priority and weights within the same priority. A
network queue's bandwidth is allocated using the "within-cir" and "above-cir" scheme normal for
port schedulers.
Queue CIR and PIR percentages when port-based schedulers are in effect will be based on frame-
offered-load calculations.
distribution.
A network queue with a port parent association exists on a port without a scheduler policy defined
will be considered to be orphaned.
