QoS Commands 649console(config-policy-classmap)#conform-color class-cos1console(config-policy-classmap)#exitconsole(config-policy-map)#exitconsole(config)#cos-queue min-bandwidthUse the cos-queue min-bandwidth command in either Global Configurationmode or Interface Configuration mode to specify the minimum transmissionbandwidth for each interface queue. To restore the default for each queue’sminimum bandwidth value, use the no form of this command.Syntaxcos-queue min-bandwidthbw-0 bw-1 …bw-nno cos-queue min-bandwidth•bw-0 — Specifies the minimum transmission bandwidth guarantee for aninterface. You must specify as many bandwidth parameters as there areCOS queues (bw-0 through bw-n). (Range: 0–100 in increments of 5)Default ConfigurationBy default, all CoS queues are configured with a 0% minimum bandwidthguarantee.Command ModeGlobal Configuration mode or Interface Configuration (gigabitethernet,port-channel, tengigabitethernet, fortygigabitethernet) modeUser GuidelinesThe maximum number of queues supported per interface is seven. It isrecommended that the operator avoid the use of queue 5-7 in order to avoidconflicts with inter- and intra-network control traffic.In order to better accommodate bursty traffic, it is recommended that thesum of the configured min-bandwidths be much less than 100%. Configuringthe minimum bandwidths such that they sum to 100% effectively locks thescheduler such that bandwidth sharing by lower priority queues cannot beaccommodated under congestion conditions.
