Have an odd thing going on with our L3 routing switch when it comes to setting radius authentication up on it. On the other switches that are not L3 with Denali 16.3.6 authentication and logging into the switches via RADIUS works fine. However, this particular switch is for some reason not connecting back to the RADIUS server.
From the Switch I can:
Ping the RADIUS server - can ping the switch from the RADIUS (NPS) server
run a terminal monitor and debug radius
open another session and log in with my AD credentials. This is where it fails. The debug shows it attempting to go out to the radius server IP but then receives 3x request timed out messages.
Its not a routing issue as i'm able to ping from the switch and from the server.
Is there something I'm missing with this version of Denali? there is no difference with my configuration here to the other switches.

Suggest to post config from switch side, i am sure there may be some logs on ACS why it failing.
