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 unicast traffic into one
of eight classes in S-Series or eight classes in case of S6000. 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.
bandwidth-percentage
Assign a percentage of weight to the class/queue.
