5.5.7 What Could Go Wrong
1 If the PC doesn't pop up the authentication message after
connecting the PC to the switch:
a. Try to use the Switch to ping Radius-Server. The Switch should
be able to ping Radius-Server.
b. Right-click on your network adapter and select Properties >
Authentication > Additional settings. Uncheck the "Validate
server certificate".
2 If the shared secret setting of Switch and PC does NOT match,
the authentication will fail.
3 If the authentication is fine, but the PC cannot ping Server,
please check 801.1X Port Authentication configurations. Do
NOT activate the authentication on the uplink port (port 2, 3,
and 12).
