Configuring portal authentication server detection

During portal authentication, if the communication between the access device and portal
authentication server is broken, both of the following occur:
•
New portal users are not able to log in.
•
The online portal users are not able to log out normally.
To address this problem, the access device needs to be able to detect the reachability changes of the
portal server quickly and take corresponding actions to deal with the changes.
With the portal authentication server detection feature, the device periodically detects portal packets
sent by a portal authentication server to determine the reachability of the server. If the device
receives a portal packet within a detection timeout (timeout timeout) and the portal packet is valid,
the device considers the portal authentication server to be reachable. Otherwise, the device
considers the portal authentication server to be unreachable.
You can configure the device to take the following actions when the server reachability status
changes:
•
Sending a log message, which contains the name, the current state, and the original state of the
portal authentication server.
•
Enabling portal fail-permit. When the portal authentication server is unreachable, the portal
fail-permit feature on an interface allows users on the interface to have network access. When
the server recovers, it resumes portal authentication on the interface. For more information, see
"Configuring the portal fail-permit
Portal packets include user login packets, user logout packets, and heartbeat packets. Heartbeat
packets are periodically sent by a server. By detecting heartbeat packets, the device can detect the
server's actual status more quickly than by detecting other portal packets.
Only the IMC portal authentication server supports sending heartbeat packets. To test server
reachability by detecting heartbeat packets, you must enable the server heartbeat feature on the
IMC portal authentication server.
