AAA server marked as dead

lni1 — Sun, 10 Mar 2019 21:47:46 GMT

We have configured 2 AAA servers for Wireless authentication purposes.

Now everything falls to the backup because the primary is marked as dead :

What are the points to check what is wrong ? The primary server is up and running, perhaps a problem with Radius ?

The problem indicates the primary ACS Server failed to respond to authentication request (radius).

The server might be up & running, and you even ping it without any problem. This has something to do with the radius (or tacacs+) services. Check the radius status from the ACS "Reports & Activity - ACS Service Monitoring", or from the server's event viewer.

Under the ACS Service monitoring, check the latest 'CSMonLog.csv' (or older file) for any CSRadius failed services.

I found it, It was the proxy distribution table that was configured faulty.

Thanks anyway for your assistance
