1.9 Troubleshooting Portal

1.9.1 Inconsistent Keys on the Access Device and the Portal Server

I. Symptom
When a user is forced to access the portal server, the portal server displays neither the
portal authentication page nor any error message. What the user sees is a blank web
page.
II. Analysis
The keys configured on the access device and the portal server are inconsistent,
causing CHAP message exchange failure. As a result, the portal server does not
display the authentication page.
III. Solution
Use the display portal server command to display the key for the portal server on
the access device and view the key for the access device on the portal server.
Use the portal server command to modify the key on the access device or modify
the key for the access device on the portal server to ensure that the keys are
consistent.

1.9.2 Incorrect Server Port Number on the Access Device

I. Symptom
After a user passes the portal authentication, you cannot force the user to log out by
executing the portal delete-user command on the access device, but the user can log
out by using the disconnect attribute on the authentication client.
II. Analysis
When you execute the portal delete-user command on the access device to force the
user to log out, the access device actively sends a REQ_LOGOUT message to the
portal server. The default listening port of the portal server is 50100. However, if the
listening port configured on the access device is not 50100, the destination port of the
REQ_LOGOUT message is not the actual listening port on the server. Thus, the portal
server cannot receive the REQ_LOGOUT message. As a result, you cannot force the
user to log out the portal server.
