Hello,
I am setting up a RADIUS server group for remote access VPN users. Everything is working fine, mostly, however I had question. What is the default behavior of the FTD for a failed RADIUS server? I can not find any information online. Basically, we have a primary and secondary RADIUS server... so that's two servers in the group. In my testing, I stopped the service on the primary server (on the actual Windows server) and the FTD started using the secondary as planned. However, when I re-enabled the primary server (by starting the service on the Windows server,) it continued using the secondary. I assume this is because the primary was marked "failed" on the FTD... though I didn't run any commands to check as the FTD is completely new to me, I hadn't thought of it. I checked all sorts of places on the FTD (via FMC) for how to configure the behavior but couldn't find anything. Is there no way for the FTD to automatically attempt to reconnect to the primary RADIUS server after some point in time or at least with some kind of manual intervention? Is there some kind of default timer the server is marked failed before it tries again? Any info is appreciated.
Thanks
Chris
