Usage Guidelines

Usage Scenario

After users go online, the administrator may modify the users' authentication parameters or network access rights on the authentication server. To ensure user validity or update the users' network access rights in real time, you can run this command to enable the device to re-authenticate the users when receiving DHCP lease renewal packets from MAC address authentication users.

Precautions

MAC address authentication users who go online through a VLANIF interface do not support re-authentication.

This function applies only to Layer 2 BNG scenarios.
