44 Quality of Service c e s Quality of Service (QoS) is supported on platforms: Differentiated service is accomplished by classifying and queuing traffic, and assigning priorities to those queues. The E-Series has eight unicast queues per port and 128 multicast queues per-port pipe. Traffic is queued on ingress and egress. By default, on ingress, all data traffic is mapped to Queue 0, and all control traffic is mapped to Queue 7. On egress control traffic is mapped across all eight queues. All queues are serviced using the Weighted Fair Queuing scheduling algorithm. You can only manage queuing prioritization on egress. The C-Series traffic has eight queues per port. Four queues are for data traffic and four are for control traffic. All queues are serviced using the Deficit Round Robin scheduling algorithm. You can only manage queuing prioritization on egress.
