Configuring Frame Relay Traffic Shaping

Before configuring Frame Relay Traffic Shaping on a Cisco router, you must enable Frame Relay encapsulation on the main interface. By default, configuring Frame Relay Traffic Shaping on the main interface enables traffic shaping with per-VC queuing for all PVCs and switched virtual circuits (SVCs) under the main interface. To configure Frame Relay

Traffic Shaping on a specified main interface, follow the configuration steps listed below:

Step 1. Go into the interface configuration mode of the main interface on which you want to configure Frame Relay Traffic Shaping. Frame Relay encapsulation must be enabled on the specified main interface.
Step 2. Enable Frame Relay Traffic Shaping with per-VC queuing on the main interface with the frame-relay traffic-shaping interface configuration command.

Example 5-1 shows a configuration example of enabling Frame Relay Traffic Shaping on an interface.

Example 5-1. Configuration Example for Enabling Frame Relay Traffic Shaping
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#interface serial4/2
Router(config-if)#encapsulation frame-relay
Router(config-if)#frame-relay traffic-shaping
Router(config-if)#

NOTE:Frame Relay Traffic Shaping can be enabled only on the main interface. Presently, it is not possible to enable traffic shaping for only a particular DLCI or a subinterface under the main interface.
