telnet to radius server 22 port succeeds, to port 1812 fails says telnet 10.16.11.12 1812 Trying 10.16.11.12, 1812 ... % Destination unreachable; gateway or host down
RADIUS on port 1812 is UDP. Telnet will never work.
why are packets not reaching the radius server even though it pings from the switch?
You have a firewall on the network or on the RADIUS server, or a switch ACL which is blocking UDP packets. -- Matthew
