iplpm link authentication-mode

Function

The iplpm link authentication-mode command configures the authentication mode and password for packet loss measurement on a direct link.

The undo iplpm link authentication-mode command deletes the authentication mode and password.

By default, no authentication mode or password is configured for packet loss measurement on a direct link.

Format

iplpm link authentication-mode hmac-sha256 key-id key-id [ cipher ] password

undo iplpm link authentication-mode

Parameters

Parameter	Description	Value
hmac-sha256	Uses HMAC-SHA256 to authenticate packets between devices.	-
key-id key-id	Specifies the ID of the authentication password.	The value is an integer that ranges from 1 to 64.
cipher	Specifies the cipher-text authentication password.	-
password	Specifies the authentication password.	The value is a character string without spaces. The value is a string of 1 to 255 characters in plain text. The value is a string of 32 to 392 characters in cipher text.

Usage Guidelines

Usage Scenario

After packet loss measurement is configured on a direct link, statistics data on received and sent packets on an interface at one end is sent to an interface at the other end and summarized for packet loss measurement. This command is used to authenticate communication packets on the direct link, improving security.

Precautions

When the authentication mode and password are configured on an interface, packets encapsulated with local statistics data sent from the interface are authenticated. Therefore, both interfaces of the direct link must be configured with the same authentication mode and password.

Example

# Set the authentication mode to hmac-sha256 and password to huawei in cipher text for packet loss measurement on a direct link on the GE0/0/1.
