If FreeRADIUS prints out NOTHING once started, no packets are arriving.

Check the Cisco config again. Use "debug" and "term mon" as appropriate.

If the Cisco is sending radius requests, then you need to resort to 
normal network connectivity diagnosis - ping, tcpdump/wireshark, check 
iptables, etc.

This is not a FreeRADIUS issue (so far).
