Link scheduler configuration task list 110IPLink 2800 Series Getting Started Guide 8 • Link scheduler configurationDefining random early detectionThe command random-detect is used to request random early detection (RED). When a queue carries lots ofTCP transfers that last longer than simple web requests, there is a risk that TCP flow-control might be ineffi-cient. A burst-tolerance index between 1 and 10 may optionally be specified (exponential filter weight). The noform of this command reverts the queue to default “tail-drop” behavior.Mode: SourceDiscarding Excess LoadThe command police controls traffic arriving in a queue for class name. The value of the first argument aver-age-kilobits defines the average permitted rate in kbps, the value of the second argument kilobits-ahead definesthe tolerated burst size in kbps ahead of schedule. Excess packets are dropped.This procedure describes defining discard excess loadMode: SourceCommand Purposenode(src)[name]#random-detect {burst-tolerance} Defines random early detection (RED) forqueues of for the selected traffic-class or policyname. The range for the optional valueburst-tolerance is from 1 to 10.Command Purposenode(src)[name]#policeaverage-kilobitsburst-sizekilobits-aheadDefines how traffic arriving in a queue for the selectedclass or policyname has to be controlled. The valueaver-age-kilobits for average rate permitted is in the rangefrom 0 to 10000 kbps. The valuekilobits-ahead for burstsize tolerated ahead of schedule is in the range from 0 to10000.
