	Configure Frame Relay QoS 263
Table 299 Create/Delete a Frame Relay class
Operation	Command
Create a Frame Relay class	fr class class-name
Delete a Frame Relay class	undo fr class class-name

By default, no Frame Relay class is created.

After creating the Frame Relay class using this command, the user will enter the frame relay class view under which you can configure the parameters like CIR.

2Associate the Frame Relay class with the Frame Relay interface or a PVC

Please configure the association between a Frame Relay class and an interface in interface view, and configure the association between a Frame Relay class and a PVC in DLCI view.

Table 300 Associate the Frame Relay class with the Frame Relay interface or a PVC

Operation	Command
Associate a Frame Relay class with a Frame	fr-classclass-name
Relay interface or PVC
Remove the association between a Frame Relay	undo fr-class class-name
class and a Frame Relay interface or PVC

By default, no Frame Relay class is associated with the Frame Relay interface or the Frame Relay PVC.

When using the command fr-class, if the specified Frame Relay class does not exist, this command will first create a Frame Relay class (but not enter the frame relay class view) and then associate it with the current interface or PVCs.

The command undo fr-classwill remove the association between the specified Frame Relay class and the interface/PVCs without deleting the actual Frame Relay class. In this case, if using the display current-configurationcommand to view the configurations of the router, you can still see the configuration of the Frame Relay class. To delete the Frame Relay class, use the undo fr class command.

When a Frame Relay PVC implements QoS, it will search for the corresponding Frame Relay class in the following sequence:

■If there is a Frame Relay class associated with the PVC, use the QoS parameters configured to the Frame Relay class.

■If there is no Frame Relay class associated with the PVC but a Frame Relay class associated with the interface to which the PVC belongs, use the QoS parameters configured to this Frame Relay class.

3 Configure the Frame Relay class parameters

Configure Frame Relay Traffic Shaping

In frame relay class view, the user can configure the parameters for the QoS, such as Frame Relay traffic shaping, Frame Relay traffic policing, Frame Relay congestion management, and Frame Relay queueing management. The following sections will cover the parameter settings in detail.

Frame Relay traffic shaping configuration includes:

■Enable the Frame Relay traffic shaping

■Create a Frame Relay class

■Associate the Frame Relay class with the Frame Relay interface or a PVC
