Cannot log out portal users on the RADIUS server
Symptom
The access device uses the HPE 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 HPE 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.
