Traffic Policing
Numerically, the value of CBS should not be less than CIR ALLOW, otherwise, the
large packets may not be sent.
Frame Relay traffic policing configuration includes:
Enable the Frame Relay traffic policing
Create a Frame Relay class
Associate the Frame Relay class with the Frame Relay interface or a PVC
Configure the parameters of Frame Relay class for Frame Relay traffic policing
1 Enable the Frame Relay Traffic Policing
Perform the following configurations in synchronous serial interface view.
Table 303 Enable/Disable the Frame Relay traffic policing
Operation
Enable the Frame Relay traffic policing
Disable the Frame Relay traffic policing
By default, the Frame Relay traffic policing is not enabled on the interface.
The function of Frame Relay traffic policing is applied on the interface receiving
the Frame Relay packets on a router. It can only be applied at the DCE side on a
Frame Relay network.
2 Create a Frame Relay class
Please refer to the above 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
Please refer to the above section "Configure Frame Relay class" for the
configuration procedure in detail.
4 Configure the parameters of Frame Relay class for Frame Relay traffic policing
Perform the following configurations in frame relay class view.
Table 304 Configure the parameters of Frame Relay class
Operation
Set the CBS of a Frame Relay PVC
Restore the CBS of a Frame Relay PVC to the default
value
Set the EBS of a Frame Relay PVC
Restore the EBS of a Frame Relay PVC to the default
value
Set the CIR ALLOW of a Frame Relay PVC
Restore the CIR ALLOW of a Frame Relay PVC to the
default value
The commands cbs, ebs, and cir allow can be used to set the inbound and
outbound parameters on a PVC. However, only the inbound parameters are
effective for the Frame Relay traffic policing.
