RADIUS/TACACS+ not responding even on the same vlan

[steven.pw.lau]

Hi,

Have anyone encountered this problem before? My radius is at 192.168.1.10 and R1 is on 192.168.1.1. Both are connected to a switch and ping works perfect. ACS has been configured with R1 as the AAA client with a key. I'm baffled as to why this does not work. I've even changed the authentication to TACACS+ and still the same problem occurs.

Tried changing the ports to 1812,1813 still the same. No Windows FW turned on in the ACS Server..

Latest update. Managed to solve the problem..

Resolution: Re-install Cisco ACS

But would definately welcome a better suggestion than the above for anyone who has experienced this problem before. Could it be Java related problem?
