Configuring VP policing
A VP is the collection of all PVCs with the same VPI value. VP policing is used to manage the maximum bandwidth of the VP, and monitor the traffic of the inbound and outbound directions of the VP on a physical interface. When the maximum transmission rate of the VP exceeds the specified value, the exceeded flows are dropped. When VP policing is applied, the parameters of PVC are still valid. Packets can be transmitted or received only when the parameters of PVC and VP policing are met. In calculating the traffic, the LLC/SNAP, MUX, and NLPID headers are included, but the ATM cell header is not included.
To configure VP policing:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter ATM interface view. | interface atm interface-number | N/A |
3. Configure parameters for VP policing. | vp limit vpi scr | By default, VP policing is disabled. |
