The whitelist session-car rbs-ipv4 command configures bandwidth parameters for CAR for IPv4 RBS sessions.
The undo whitelist session-car rbs-ipv4 command restores the default bandwidth parameter values for CAR for IPv4 RBS sessions.
The default CIR, CBS, PIR, and PBS of CAR for IPv4 RBS sessions are 12 kbit/s, 1500 bytes, 6000 kbit/s, and 750000 bytes, respectively.
| Parameter | Description | Value |
|---|---|---|
| cir cir-value |
Specifies a committed information rate (CIR), that is, the average rate at which packets can be transmitted or forwarded. |
The value is an integer that ranges from 0 to 1000000, in kbit/s. The default value is 12. |
| cbs cbs-value |
Specifies a committed burst size (CBS), that is, the committed burst traffic that can instantaneously pass through. |
The value is an integer that ranges from 0 to 9000000, in bytes. The default value is 1500. |
| pir pir-value |
Specifies a peak information rate (PIR), that is, the highest rate at which packets can be transmitted or forwarded. |
The value is an integer that ranges from 0 to 1000000, in kbit/s. The default value is 6000. It is recommended that pir-value be greater than or equal to cir-value. |
| pbs pbs-value |
Specifies a peak burst size (PBS), that is, the peak burst traffic that can instantaneously pass through. |
The value is an integer that ranges from 0 to 9000000, in bytes. The default value is 750000. It is recommended that pbs-value be greater than or equal to cbs-value. |
Usage Scenario
When a large number of IPv4 RBS packets are sent to the CPU, you can run the whitelist session-car rbs-ipv4 command to adjust bandwidth parameters for CAR for IPv4 RBS sessions to ensure that IPv4 RBS packets can be properly sent to the CPU.
Precautions
In normal cases, adjusting the default bandwidth parameters for CAR for IPv4 RBS sessions is not recommended. Use the default values instead.
