whitelist session-car telnet-server

Function

The whitelist session-car telnet-server command sets values for Telnet whitelist session CAR parameters.

The undo whitelist session-car telnet-server command restores the default values for Telnet whitelist session CAR parameters.

By default, the CIR, CBS, PIR, and PBS of Telnet whitelist session CAR are 4 kbit/s, 640 bytes, 64 kbit/s, and 10000 bytes, respectively.

Format

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

undo whitelist session-car telnet-server [ { 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 is an integer ranges from 0 to 1000000, in kbit/s. The default value is 4.
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 ranges from 0 to 1000000, in bytes. The default value is 640.
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 ranges from 0 to 1000000, in kbit/s. The default value is 64.
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 ranges from 0 to 1000000, in bytes. The default value is 10000.

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 ranges from 0 to 1000000, in kbit/s. The default value is 4.

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 ranges from 0 to 1000000, in bytes. The default value is 640.

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 ranges from 0 to 1000000, in kbit/s. The default value is 64.

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 ranges from 0 to 1000000, in bytes. The default value is 10000.

Usage Guidelines

Usage Scenario

To adjust the packet channel bandwidth for Telnet session CAR on a device, run the whitelist session-car telnet-server command. If the device receives a large number of Telnet Server packets, this configuration ensures that the packets that hit the Telnet Server whitelist (session CAR) can be sent to Telnet Server properly.

The PIR must be greater than or equal to the CIR, and the PBS must be greater than or equal to the CBS.

Implementation Procedure

If a session Telnet Server parameter in an Telnet whitelist is set to an excessively large or small value, the involved Telnet Server 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 Telnet whitelist. Use the default values of these parameters instead.

Example

# Set parameters for Telnet session CAR.

<HUAWEI> system-view
[~HUAWEI] whitelist session-car telnet-server cir 100 cbs 500000 pir 2000 pbs 900000
Warning: If the parameters of Session-CAR in the whitelist are too large or too small, the neighbor relationship may be disconnected or flap. You are advised to use the default values.
