1 Enable the Frame Relay traffic shaping
Perform the following configurations in synchronous serial interface view.
Table 301 Enable/Disable the Frame Relay traffic shaping
By default, the Frame Relay traffic shaping is not enabled on the interface.
The function of Frame Relay traffic shaping is applied on the outgoing interfaces
on a router. Usually it is applied at the DTE end on a Frame Relay network.
2 Create a Frame Relay class
Refer to the previous section “Configure Frame Relay class” for the configuration
procedure in detail.
3 Associate the Frame Relay class with the Frame Relay interface or a PVC
Refer to the previous section “Configure Frame Relay class” for the configuration
procedure in detail.
4 Configure the Frame Relay class parameters for Frame Relay traffic shaping
Perform the following configurations in frame relay class view.
Table 302 Configure the parameters of Frame Relay class
The commands cbs, ebs, and cir allow can be used to set the inbound and
outbound parameters. However, only the outbound parameters are effective for
the Frame Relay traffic shaping.
