Service SAP QoS Policy Command Reference
In this context, the port-parent command is mutually exclusive to the parent command (used to
create a parent/child association between a queue and an intermediate scheduler). Executing a port-
parent command when a parent definition is in place causes the current intermediate scheduler
association to be removed and replaced by the defined port-parent association. Executing a parent
command when a port-parent definition exists causes the port scheduler association to be removed and
replaced by the defined intermediate scheduler name.
Changing the parent context on a SAP egress policy queue may cause a SAP or subscriber or multi-
service site context of the queue (policy associated with a SAP or subscriber profile or multi-service
site) to enter an orphaned state. If an instance of a queue is created on a port or channel that does not
have a port scheduler enabled and the sap-egress policy creating the queue has a port-parent
association, the queue will be allowed to run according to its own rate parameters and will not be
controlled by a virtual scheduling context. If an instance of a queue is on a port or channel that has a
port scheduler configured and the sap-egress policy defines the queue as having a non-existent
intermediate scheduler parent, the queue will be treated as an orphan and will be handled according to
the current orphan behavior on the port scheduler.
The no form of this command removes a port scheduler parent association for the queue or scheduler.
If a port scheduler is defined on the port which the queue or scheduler instance exists, the queue or
scheduler will become orphaned if an port scheduler is configured on the egress port of the queue or
scheduler.
Default
no port-parent
Parameters
weight weight — Defines the weight the queue or scheduler will use at the above-cir port priority
level level — Defines the port priority the queue or scheduler will use to receive bandwidth for its
cir-weight cir-weight — Defines the weight the queue or scheduler will use at the within-cir port
364
level (defined by the level parameter).
Values
0 to 100
Default
1
above-cir offered-load.
Values
1 to 8 (8 is the highest priority)
Default
1
priority level (defined by the cir-level parameter). The weight is specified as an integer value
from 0 to 100 with 100 being the highest weight. When the cir-weight parameter is set to a
value of 0 (the default value), the queue or scheduler does not receive bandwidth during the
port schedulers within-cir pass and the cir-level parameter is ignored. If the cir-weight
parameter is 1 or greater, the cir-level parameter comes into play.
Values
0 to 100
