Troubleshooting 802.1X
EAD assistant URL redirection failure
Symptom
Unauthenticated users are not redirected to the specified redirect URL after they enter external
website addresses in their Web browsers.
Analysis
Redirection will not happen for one of the following reasons:
•
The address is in the string format. The operating system of the host regards the string as a
website name and tries to resolve the string. If the resolution fails, the operating system sends
an ARP request, but the target address is not in the dotted decimal notation. The redirection
feature does redirect this kind of ARP request.
•
The address is within a free IP segment. No redirection will take place, even if no host is present
with the address.
•
The redirect URL is not in a free IP segment.
