5760 not supporting RADIUS 1645,1646 ports anymore?
during configuration I was encountering difficulties getting the 5760 to speak with our RADIUS servers.
I merely configured the server with the IP address within the radius server sub menu. The WLC would then take the old ports by default.
Everytime I tried to authenticate I got the error that the radius servers are dead. After some seconds I saw the message that the radius server is responding again.
After changing the ports to the 1812 and 1813 all of them started to respond. I thought that this might be restricted on the server, but this is not the case as our old WLCs still use 1645 and 1646 communicating with the very same servers.
Taking a look at the ACS 5 I could only find the option to configure a port for TACACS, but not for RADIUS.
Any official word on this? Configuration guide doesn't state anything about this either.
