Re: problems with cisco 3550 and radius

what was the source interface configured for the radius authentication?

Re: problems with cisco 3550 and radius

From the description of the symptoms in the original post I believe that Narayan is on the right track. It sounds like the port that is being shut down has the IP address that the Radius server is configured to use. With the port shut down it sounds like a different address is being used as the source address for the authentication request, but the Radius server will not authenticate the request because it is from a source address that it does not recognize. The solution to this issue is usually to configure an address to use (like a loopback) so that no matter what interface is used to send the authentication request the source address will be the one the Radius server is expecting. Can the original poster confirm whether this is the case or not?
