The value of the object tSapEgressParentLocation specifies the location in which queues will look to find their parent scheduler; in case the parent scheduler is not found, the queue will be orphaned. The value of tSapEgressParentLocation applies to all queues in this sap-egress policy which have parents configured; for queues with no parent configured (or which are port-parented), tSapEgressParentLocation has no effect. The value 'default' specifies that the queues should look for their parent in the default way; i.e. SAP queues will look for their parents in the SAP's egress scheduler policy or the multi-service-site's egress scheduler policy depending on which is configured and Subscriber queues will look for their parents in the subscriber profile's egress scheduler policy. The value 'sla' specifies that the queues should look for their parent in the SLA-profile's egress scheduler policy; all queues that are not port-parented and to which SLA-profile is not applicable will behave as orphans in this case.
