Usage Guidelines

Usage Scenario

The users in the survival state can only access limited network resources after the device assigns specified network access rights to users who fail authentication because the authentication server is Down. To meet the users' normal network access requirements, the device needs to re-authenticate users in the survival state in real time when the authentication server turns Up.

After the status of the RADIUS server is set to Down, you can run the radius-server dead-time dead-time command to set the interval for the RADIUS server to return to the active state. When the value of dead-time expires, the status of the RADIUS server is set to forcible Up. When the server successfully transmits and receives packets, the status is set to Up. The device can re-authenticate users in the survival state when the server changes from Down or forcible Up to Up. Re-authentication cannot be triggered when the server turns from Down to forcible Up.

Prerequisites

The radius-server testuser command has been configured in the RADIUS server template so that the device can detect that the authentication server changes from Down to Up.

Precautions

This function takes effect only for users who go online after this function is successfully configured.
