We have implemented new Microsoft 2008 NPS Radius for authentification wireless controller.
i am seeing RADIUS server x.x.x.x:1812 failed to respond to request (ID 119) for client ............. in controller. But there no logs hitting to the NPS server either failed or success or other related.
Layer 3 comminucation is fine between controller & server.
As per the debug logs,controller forwarding request NPS server "Successful transmission of Authentication Packet tp ......NPS proxy ".
But there is no further key exchange or successful authentication logs, any idea on this?
Re: Microsoft 2008 NPS Radius + wireless controller.
Download NTRadPing and test to see if your radius is working. You can put a sniffer on and see if you see packets coming out of the wlc and radius. You can always remove the aaa from the wlc and add it back on and also remove and add back on the wlc as a aaa client on the radius server.
