whitelist session-car isis

Function

The whitelist session-car isis command sets the parameters of whitelist session-CAR for IS-IS.

The undo whitelist session-car isis command restores the parameters of whitelist session-CAR for IS-IS to the default values.

By default, whitelist session-CAR for IS-IS is enabled.

Format

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

undo whitelist session-car isis [ { 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), which limits the maximum number of bytes available for a burst of packets in a short interval to remain within CIR.	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 highest rate at which packets can be transmitted or forwarded.	The value ranges from 0 to 1000000, in kbit/s. The default value is 20000.
pbs pbs-value	Specifies a peak burst size (PBS), which limits the maximum number of bytes available for a burst of packets in a short interval to remain within PIR.	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.

cbs cbs-value

Specifies a committed burst size (CBS), which limits the maximum number of bytes available for a burst of packets in a short interval to remain within CIR.

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 highest rate at which packets can be transmitted or forwarded.

The value ranges from 0 to 1000000, in kbit/s. The default value is 20000.

pbs pbs-value

Specifies a peak burst size (PBS), which limits the maximum number of bytes available for a burst of packets in a short interval to remain within PIR.

The value ranges from 0 to 10000000, in bytes. The default value is 9000000.

Usage Guidelines

Usage Scenario

To adjust the packet channel bandwidth for IS-IS session-CAR on a device, run the whitelist session-car isis command. This configuration ensures that the IS-IS packets can be properly sent if the device receives a large number of such packets.

Configuration Impact

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

Precautions

You are advised not to change the values of session-CAR parameters in IS-IS whitelists, except under abnormal circumstances. Use the default values for 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.
