Generic Commands
level level —
other child schedulers and queues vying for bandwidth on the parent scheduler-name during
the 'above CIR' distribution phase of bandwidth allocation. During the above CIR distribution
phase, any queues or schedulers defined at a lower strict level receive no parental bandwidth
until all queues and schedulers defined with a higher (numerically larger) strict level on the
parent have reached their maximum bandwidth or have satisfied their offered load require-
ments.
When the similar cir-level parameter default (undefined) are retained for the child scheduler, bandwidth
is only allocated to the scheduler during the above CIR distribution phase.
Children of the parent scheduler with a lower strict priority level will not receive bandwidth until all
children with a higher strict priority level have either reached their maximum bandwidth or are idle.
Children with the same strict level are serviced according to their weight.
Values
Default
cir-weight cir-weight — The cir-weight keyword defines the relative weight of this scheduler in
comparison to other child schedulers and queues at the same
parameter. Within the strict cir-level, all cir-weight values from active children at that level are
summed and the ratio of each active child's cir-weight to the total is used to distribute the available
bandwidth at that level. A cir-weight is considered to be active when the queue or scheduler that the
cir-weight pertains to has not reached the CIR and still has packets to transmit.
A 0 (zero) cir-weight value signifies that the child scheduler will receive bandwidth only after
bandwidth is distributed to all other non-zero weighted children in the strict cir-level.
Values
Default
cir-level cir-level — The cir-level keyword defines the strict priority CIR level of this scheduler in
comparison to other child schedulers and queues vying for bandwidth on the parent
during the 'within CIR' distribution phase of bandwidth allocation. During the 'within CIR' distribution
phase, any queues or schedulers defined at a lower strict CIR level receive no parental bandwidth until
all queues and schedulers defined with a higher (numerically larger) strict CIR level on the parent have
reached their CIR bandwidth or have satisfied their offered load requirements.
If the scheduler's cir-level parameter retains the default (undefined) state, bandwidth is only allocated
to the scheduler during the above CIR distribution phase.
Children with the same strict cir-level are serviced according to their cir-weight.
