car (user group view)
Function
The car command enables traffic control for users in a user group.
The undo car command disables traffic control for users in a user group.
By default, traffic control is disabled for users in a user group.
Only the S5720-EI, S5720-HI, S5730-HI, S5731-H,?S5731S-H, S5731-S, S5731S-S, S6720-HI, S5732-H, S6730-H, S6730S-H, S6730-S, S6730S-S, S6720-EI, and S6720S-EI support this command, and the user group CAR can only be applied in the interface outbound direction (outbound) on the S5720-EI, S6720-EI, and S6720S-EI.
Format
car { outbound | inbound } cir cir-value [ pir pir-value | cbs cbs-value | pbs pbs-value ] *
undo car { outbound | inbound }
Parameters
| Parameter | Description | Value |
|---|---|---|
outbound |
Applies the user group CAR to the outgoing packets on an interface to restrict the outgoing packet rate. |
- |
inbound |
Applies the user group CAR to the incoming packets on an interface to restrict the incoming packet rate. |
- |
cir cir-value |
Specifies the committed information rate (CIR), which is the average rate of traffic that can pass through an interface. |
The value is an integer that ranges from 64 to 4294967295, in kbit/s. |
pir pir-value |
Specifies the peak information rate (PIR), which is the maximum rate of traffic that can pass through an interface. |
The value is an integer that ranges from 64 to 4294967295, in kbit/s. The PIR value must be greater than or equal to the CIR value. The default PIR value is equal to the CIR value. |
cbs cbs-value |
Specifies the committed burst size (CBS), which is the average volume of burst traffic that can pass through an interface. |
The value is an integer that ranges from 10000 to 4294967295, in bytes. The default value of cbs-value is 188 x cir-value. |
pbs pbs-value |
Specifies the peak burst size (PBS), which is the maximum volume of burst traffic that can pass through an interface. |
The value is an integer that ranges from 10000 to 4294967295, in bytes. The value of pbs-value must be larger than that of cbs-value and is equal to 188 times of the value of pir-value by default. |
Usage Guidelines
Usage Scenario
After user groups are created using the user-group command, you can run the car outbound command to configure traffic control for users in a user group so that users in different groups are allocated different bandwidths.
Precautions
The car command takes effect on each user in a user group.
This function takes effect only for users who go online after this function is successfully configured.
