The whitelist session-car self-ping command sets Session-CAR parameters for the self-ping whitelist.
The undo whitelist session-car self-ping command restores the default Session-CAR values for the self-ping whitelist.
By default, the CIR, CBS, PIR, and PBS of the Session-CAR function for the self-ping whitelist are 256 kbit/s, 50000 bytes, 600 kbit/s, and 76800 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 ranging from 1 to 1000000, in kbit/s. The default value is 256. |
| cbs cbs-value |
Specifies a committed burst size (CBS), that is, the committed volume of burst traffic that can pass instantly. |
The value is an integer ranging from 1 to 9000000, in bytes. The default value is 50000. |
| pir pir-value |
Specifies a peak information rate (PIR), that is, the peak rate at which packets can be transmitted or forwarded. |
The value is an integer ranging from 1 to 1000000, in kbit/s. The default value is 600. |
| pbs pbs-value |
Specifies a peak burst size (PBS), that is, the peak volume of burst traffic that can pass instantly. |
The value is an integer ranging from 1 to 9000000, in bytes. The default value is 76800. |
Usage Scenario
If a device receives a large number of self-ping messages, you can run the whitelist session-car self-ping command to modify the bandwidth values as needed for the message channels between self-ping sessions. This configuration ensures that self-ping messages can be properly sent.
Precautions
pir-value must be greater than or equal to cir-value. If you attempt to set a pir-value value smaller than cir-value, the following error message will be displayed: "Error: The pir %d must be greater than or equal to the cir %d."
pbs-value must be greater than or equal to cbs-value. If you attempt to set a pbs-value value smaller than cbs-value, the following error message will be displayed: "Error: The pbs %d must be greater than or equal to the cbs %d."
