service-class bandwidth-percentage Specify a minimum bandwidth for queues. Syntax service-class bandwidth-percentage queue0 number queue1 number queue2 number queue3 number Parameters number Enter the bandwidth-weight, as a percentage. The range is from 1 to 100. Defaults Command Modes Command History none CONFIGURATION Version 9.4(0.0) Supported on the FN I/O aggregator. This command is supported in Programmable-Mux (PMUX) mode only. Usage Information Guarantee a minimum bandwidth to different queues globally using the serviceclass bandwidth-percentage command from CONFIGURATION mode. The command is applied in the same way as the bandwidth-percentage command in an output QoS policy. The bandwidth-percentage command in QOSPOLICY-OUT mode supersedes the service-class bandwidth-percentage command. When you enable ETS, the egress QoS features in the output QoS policy-map (such as service-class bandwidth-percentage and bandwidth-percentage), the default bandwidth allocation ratio for egress queues are superseded by ETS configurations. This is to provide compatibility with DCBX. Therefore, Dell Networking OS recommends disabling ETS when you wish to apply these features exclusively. After you disable ETS on an interface, the configured parameters are applied. Policy-Based QoS Commands Policy-based traffic classification is handled with class maps. These maps classify unicast traffic into one of four classes. The system allows 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. Syntax bandwidth-percentage percentage To remove the bandwidth percentage, use the no bandwidth-percentage command. Parameters percentage Enter the percentage assignment of weight to the class/ queue. The range is from 1 to 100% (granularity 1%). 397
