MQC-Based Frame Relay Traffic ShapingHow to Configure MQC-Based Frame Relay Traffic ShapingCreating a Shaping Policy Map and Entering FRTS Parameters for the DefaultClass MapSUMMARY STEPSDETAILED STEPSTo create a shaping policy map and enter FRTS values for the default class map, use the followingcommands:1. policy-map policy-map-name2. class class-default3. shape [average | peak] mean-rate [[burst-size] [excess-burst-size]]4. shape adaptive mean-rate-lower-bound5. shape fecn-adaptStep 1Step 2Step 3Command or Actionpolicy-map policy-map-nameExample:Router(config-pmap-c)# policy-mapshape_policy_mapclass class-defaultExample:Router(config-pmap)# class class-defaultshape [average | peak] mean-rate [[burst-size][excess-burst-size]]Example:Router(config-pmap-c)# shape average 64000PurposeCreates a policy map that can be attached to one or moreinterfaces to specify a service policy.• The example command creates a policy map namedshape_policy_map.Specifies the default class (commonly known as theclass-default class) before you configure its policy. Theclass-default class is the class to which traffic is directed ifthat traffic does not satisfy the match criteria of otherclasses whose policy is defined in the policy map.• There is only one class defined with this command (theclass-default class); therefore, it will match all traffic.Shapes traffic to the indicated bit rate according to thealgorithm specified.• The example command configures a shape entity with acommitted information rate (CIR) of 64 kbps.• Any FRTS commands supported by this feature can beused for traffic shaping. Refer to the “Restrictions forMQC-Based Frame Relay Traffic Shaping” section fora list of supported FRTS commands.7
