I get these periodically during the day on the router syslog.
Feb 16 19:33:22.817 EDT: %RADIUS-4-RADIUS_DEAD: RADIUS server x.x.x.x:1645,1646 is not responding.
Feb 16 19:33:22.817 EDT: %RADIUS-4-RADIUS_ALIVE: RADIUS server x.x.x.x:1645,1646 is being marked alive.
We have radius on a Windows Network Policy Server on two servers. CPU/Memory/Bandwidth are never more than 50% utilization.
Router#sh run | inc radius
ip radius source-interface GigabitEthernet0/0/0.x
radius server Salt
radius server Pepper
What does this tell me? How do I fix it?

Sorry I was busy last days
Now the server is detect life dead
if we merge two issue together we get same result there is interface congestion that drop control/mgmt traffic
show policy-map interface <<- share this if you can

- Check if the router has a solid network connection to the radius server.
+ Check the radius server's logs when that happens .

As it turns out that second Radius server was decommissioned 6 months ago. I need to rebuilt it using the same line in the configuration and the IP.
Currently they have a Windows Radius solution. Should I just build a second Windows Radius server or leverage ISE for this?
How do you integrate two different Radius server platforms?

- You may for instance compare performance rates as mentioned in https://www.cisco.com/c/en/us/td/docs/security/ise/performance_and_scalability/b_ise_perf_and_scale.html#reference_dfk_mjh_m5b with other radius servers
>...How do you integrate two different Radius server platforms?
- Try to keep them the same ; the authenticating policies will become more complicated for instance and
or playing with load balance or timeout settings will loose it's efficiency or disappear ,
