Usage Guidelines

Usage Scenario

After a shared key is configured using the shared-key command, the Portal packet exchanged between the device and Portal server carries an authenticator generated according to the shared key, and the authenticator is used to check whether the Portal packet at the receiver is correct. This effectively improves the information exchange security.

Precautions

To improve security, it is recommended that the password contains at least two types of lower-case letters, upper-case letters, numerals, and special characters, and contains at least 16 characters.

Example

# Configure the shared key in the Portal server template huawei to huawei@123.

<HUAWEI> system-view
[HUAWEI] web-auth-server huawei
[HUAWEI-web-auth-server-huawei] shared-key cipher huawei@123
