• 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 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 access device uses the
source port in the logout request as the destination port in the logout ACK message. As a result, the portal
authentication server can definitely receive the logout ACK message and log out the user.
Solution
1. Use the display portal server command to display the listening port of the portal authentication
server configured on the access device.
2. Use the portal server command in system view to change the listening port number to the actual
listening port of the portal authentication server.
Cannot log out portal users on the RADIUS server
Symptom
The access device uses the HP IMC server as the RADIUS server to perform identity authentication for
portal users. You cannot log out the portal users on the RADIUS server.
Analysis
The HP IMC server uses session control packets to send disconnection requests to the access device. On
the access device, the listening UDP port for session control packets is disabled by default. Therefore, the
access device cannot receive the portal user logout requests from the RADIUS server.
Solution
On the access device, execute the radius session-control enable command in system view to enable the
RADIUS session control function.
