whitelist session-car ospf

Function

The whitelist session-car ospf command sets parameters for OSPF whitelist Session-CAR.

The undo whitelist session-car ospf command restores the parameters for OSPF whitelist Session-CAR to the default values.

By default, the OSPF whitelist Session-CAR function is enabled.

Format

whitelist session-car ospf { cir cir-value | cbs cbs-value | pir pir-value | pbs pbs-value } ^*

undo whitelist session-car ospf [ { cir cir-value | cbs cbs-value | pir pir-value | pbs pbs-value } ^* ]

Parameters

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 ranges from 0 to 1000000, in kbit/s. The default value is 8.
cbs cbs-value	Specifies a committed burst size (CBS), that is, the committed volume of burst traffic that can pass instantly.	The value ranges from 0 to 1000000, in bytes. The default value is 100000.
pir pir-value	Specifies a peak information rate (PIR), that is, the peak rate at which packets can be transmitted or forwarded.	The value ranges from 0 to 1000000, in kbit/s. The default value is 16000.
pbs pbs-value	Specifies a peak burst size (PBS), that is, the peak volume of burst traffic that can pass instantly.	The value ranges from 0 to 10000000, in bytes. The default value is 9000000.

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 ranges from 0 to 1000000, in kbit/s. The default value is 8.

Specifies a committed burst size (CBS), that is, the committed volume of burst traffic that can pass instantly.

The value ranges from 0 to 1000000, in bytes. The default value is 100000.

pir pir-value

Specifies a peak information rate (PIR), that is, the peak rate at which packets can be transmitted or forwarded.

The value ranges from 0 to 1000000, in kbit/s. The default value is 16000.

pbs pbs-value

Specifies a peak burst size (PBS), that is, the peak volume of burst traffic that can pass instantly.

Usage Guidelines

Usage Scenario

To adjust the packet channel bandwidth for OSPF Session-CAR on a device, run the whitelist session-car ospf command. If the device receives a large number of OSPF packets, this configuration ensures that the packets can be properly sent.

Implementation Procedure

If a Session-CAR parameter in an OSPF whitelist is set to an excessively large or small value, the involved OSPF neighbor relationships may be disconnected or flap.

Precautions

In normal cases, you are advised not to change the values of the Session-CAR parameters in an OSPF whitelist. Use the default values of these parameters instead.
The PIR must be greater than or equal to the CIR, and the PBS must be greater than or equal to the CBS.

Example

# Set values for the OSPF whitelist session-CAR parameters.
