Troubleshooting portal

No portal authentication page is pushed for users

Symptom
When a user is redirected to the IMC portal authentication server, no portal authentication page or
error message is prompted for the user. The login page is blank.
Analysis
The key configured on the portal access device and that configured on the portal authentication
server are inconsistent. As a result, packet verification fails, and the portal authentication server
refuses to push the authentication page.
Solution
Use the display portal server command on the access device to check whether a key is configured
for the portal authentication server.
•
If no key is configured, configure the right key.
•
If a key is configured, use the ip or ipv6 command in the portal authentication server view to
correct the key, or correct the key configured for the access device on the portal authentication
server.

Cannot log out portal users on the access device

Symptom
You cannot use the portal delete-user command on the access device to log out a portal user, but
the portal user can log out by clicking the Disconnect button on the portal authentication client.
Analysis
When you execute the portal delete-user command on the access device to log out a user, the
access device sends an unsolicited logout notification message to the portal authentication server.
The destination port number in the logout notification is the listening port number of the portal
authentication server configured on the access device. If this listening port number is not the actual
listening port number configured on the server, the server cannot receive the notification. As a result,
the portal server does not log out the user.
When a user uses the Disconnect button on the authentication client to log out, the portal
authentication server sends an unsolicited logout request message to the access device. The
