Usage Information After you configure a unicast queue as strict-priority, that particular queue, on the entire chassis, is treated as a strict-priority queue. Traffic for a strict priority is scheduled before any other queues are serviced. For example, if you send 100% line rate traffic over the SP queue, it starves all other queues on the ports on which this traffic is flowing. Policy-Based QoS Commands Policy-based traffic classification is handled with class maps. These maps classify data traffic into one of eight classes . Dell Networking OS enables you to match multiple class maps and specify multiple match criteria. Policy-based QoS is not supported on logical interfaces, such as port-channels, VLANS, or loopbacks. 1322 Quality of Service (QoS)
