The port-based egress scheduler can be used to allocate bandwidth to each service or subscriber or multiservice site associated with the port. While egress policers and queues on the service can have a child association with a scheduler policy on the SAP or multiservice site, all policers and queues must vie for bandwidth from an egress port. Two methods are supported to allocate bandwidth to each service or subscriber or multiservice site queue:
-
service or subscriber or multiservice site queue association with a scheduler on the SAP or multiservice site, either of which is associated with a port-level scheduler
-
service or subscriber or multiservice site queue association directly with a port-level scheduler
