Recently I try to build up the SNAC. However, after enbling the SNAC, it is impossible for my computer to access to internet.

dc: 192.168.0.1
NPS(Windows Radius Server): 192.168.0.1
My lan-enforcer ip : 192.168.0.12
Cisco SW command: radius-server host 192.168.0.12 auth-port 1812 acct-port 1813 key @@@@
Action: all open ports.

Event that my computer could not access.

I found that in the SW, there is error: Radius dead lanenforcer no responding, Radius alive lanenforcer returns.

I dont know why. Could some one help me?
