Usage Scenario
If the device is configured to assign network access rights to users when the Portal server is Down, users can access limited network resources after the device detects that the Portal server is Down. To ensure that users can obtain normal network access rights after the Portal server goes Up, you can enable the device to re-authenticate users when the Portal server changes from Down to Up. After the Portal server goes Up, the device sets the status of users who display web-server-down to pre-connection. The re-authentication process starts when the users visit any web page. If the authentication succeeds, the device assigns normal network access rights to the users.
