How to Configure MQC-Based Frame Relay Traffic ShapingMQC-Based Frame Relay Traffic ShapingDETAILED STEPSStep 1Step 2Command or Actionclass-map class-map-nameExample:Router(config)# class-map voicematch match-criteriaExample:Router(config-cmap)# match ip dscp efPurposeCreates a class map to be used for matching packets to aspecified class.• The example command creates a class map named“voice”.Identifies packets that will belong to the class map.• The example command identifies an IP differentiatedservice code point (DSCP) value of EF (101110) as amatch criterion for the class map named “voice”.Creating a Policy Map and Entering CBWFQ Parameters for the Class MapTo create a policy map and enter CBWFQ parameters for the class map, use the following commands:SUMMARY STEPS1. policy-map policy-map-name2. class name3. priority {bandwidth-kbps | percent percentage} [burst]DETAILED STEPSStep 1Step 2Step 3Command or Actionpolicy-map policy-map-nameExample:Router(config)# policy-map llqclass nameExample:Router(config-pmap)# class voicepriority {bandwidth-kbps | percent percentage}[burst]Example:Router(config-pmap-c)# priority 32PurposeCreates a policy map that can be attached to one or moreinterfaces to specify a service policy.• The example command creates a policy map named“llq”. This policy map will be used for low latencyqueueing (LLQ).Specifies the name of the class whose policy you want tocreate.• The example command creates a traffic class named“voice”.(Optional) Gives priority to a class of traffic belonging to apolicy map.• The example command provides a guaranteed allowedbandwidth of 32 kbps and a guaranteed low latency forup to 32 kbps to the traffic class “voice” that wascreated in Step 2.6
