Configuring Frame Relay Traffic ShapingConfiguring Frame RelayCommandRouter(config-if)# no frame-relay lapf frmrPurposeSelects not to send FRMR frames at the LAPF Frame Reject procedure.By default, the Frame Reject frame is sent at the LAPF Frame Reject procedure.NoteManipulation of Layer 2 parameters is not recommended if you do not know well the resulting functionalchange. For more information, refer to the ITU-T Q.922 specification for LAPF.If you must change Layer 2 parameters for your network environment and you understand the resultingfunctional change, use the following commands as needed:CommandPurposeRouter(config-if)# frame-relay lapf k number Sets the LAPF window size k.Router(config-if)# frame-relay lapf n200 retries Sets the LAPF maximum retransmission count N200.Router(config-if)# frame-relay lapf n201 bytesRouter(config-if)# frame-relay lapf t200 tenths-of-a-secondRouter(config-if)# frame-relay lapf t203 secondsSets maximum length of the Information field of theLAPF I frame N201, in bytes.Sets the LAPF retransmission timer value T200, intenths of a second.Sets the LAPF link idle timer value T203 of DLCI 0, inseconds.Configuring Frame Relay Traffic ShapingTraffic shaping applies to both PVCs and SVCs. For information about creating and configuring SVCs,see the section “Configuring Frame Relay SVCs” earlier in this chapter.To configure Frame Relay traffic shaping, perform the tasks in the following sections:• Enabling Frame Relay Encapsulation on an Interface (earlier in this chapter)• Defining VCs for Different Types of Traffic• Enabling Frame Relay Traffic Shaping on the Interface• Configuring Enhanced Local Management Interface• Specifying a Traffic-Shaping Map Class for the Interface• Defining a Map Class with Queueing and Traffic-Shaping Parameters• Defining Access Lists• Defining Priority Queue Lists for the Map Class• Defining Custom Queue Lists for the Map ClassNoteFrame Relay traffic shaping is not effective for Layer 2 PVC switching using the frame-relay routecommand.12
