Configuring Class-of-Service 1155CoS Interface Configuration CommandsBeginning in Privileged Exec mode, use the following commands in toconfigure the traffic shaping and WRED exponent values for an interface.Interface Queue ConfigurationBeginning in Privileged Exec mode, use the following commands in toconfigure and view CoS interface queue settings.CLI Command Descriptionconfigure Enter Global Configuration mode.interfaceinterface Enter Interface Configuration mode, whereinterfaceis replaced by tengigabitethernetunit/slot/port orport-channelport-channel number.traffic-shapebw kbps Sets the upper limit on how much traffic can leave aport. Thebw variable represents the shapingbandwidth value from 64 to 4294967295 kbps.random-detect exponential-weighting-constantexponentConfigure the WRED decay exponent (range: 0–15)for the interface. The weighting constant exponentdetermines how much of the previous average queuelength sample is added to the current average queuelength. A value of 0 indicates that no weight is givento the previous sample and only the instantaneousrate is used. A value of 1 indicates that 1/2 of thedifference between the instantaneous value and theprevious value is added to the current value; a value of2 implies that 1/4 of the difference is added, 3 implies1/8 of the difference is added, etc.CLI Command Descriptionconfigure Enter Global Configuration mode.interfaceinterface Enter Interface Configuration mode, whereinterface isreplaced by tengigabitethernetunit/slot/port. or port-channelport-channel number.cos-queue min-bandwidthbwSpecify the minimum transmission bandwidth (range:0-100% in 1% increments) for each interface queue.
