mls qos queue-set output buffersChapter 2Catalyst 3750-E and 3560-E Switch Cisco IOS Commandsmls qos queue-set output buffersUse the mls qos queue-set output buffers global configuration command on the switch stack or on astandalone switch to allocate buffers to a queue-set (four egress queues per port). Use the no form of thiscommand to return to the default setting.mls qos queue-set output qset-id buffers allocation1 ... allocation4no mls qos queue-set output qset-id buffersSyntax Descriptionqset-idallocation1 ...allocation4ID of the queue-set. Each port belongs to a queue-set, which defines all thecharacteristics of the four egress queues per port. The range is 1 to 2.Buffer space allocation (percentage) for each queue (four values for queues 1 to 4).For allocation1, allocation3, and allocation4, the range is 0 to 99. For allocation2,the range is 1 to 100 (including the CPU buffer). Separate each value with a space.DefaultsAll allocation values are equally mapped among the four queues (25, 25, 25, 25). Each queue has 1/4 ofthe buffer space.Command ModesGlobal configurationCommand HistoryRelease12.2(35)SE2ModificationThis command was introduced.Usage GuidelinesSpecify four allocation values, and separate each with a space.Allocate buffers according to the importance of the traffic; for example, give a large percentage of thebuffer to the queue with the highest-priority traffic.To configure different classes of traffic with different characteristics, use this command with the mls qosqueue-set output qset-id threshold global configuration command.NoteThe egress queue default settings are suitable for most situations. You should change them only whenyou have a thorough understanding of the egress queues and if these settings do not meet your QoSsolution.2-364Catalyst 3750-E and 3560-E Switch Command ReferenceOL-9776-08
