Radius Server Dead/ Alive Problem/Flap

[OJ_Magellan]

Hi All,

I'm getting the following Radius message on a 9300 IOS XE 17.3 Switch:

373543: Apr 16 12:29:12.104: %RADIUS-4-RADIUS_DEAD: RADIUS server x.x.x.x:1812,1813 is not responding.
373556: Apr 16 12:33:24.563: %RADIUS-4-RADIUS_DEAD: RADIUS server x.x.x.x:1812,1813 is being marked alive.

The Radius Server (ISE) is pingable, and I've used the "test aaa ... " Command to see if the authentication works, and it did as intended.

Any Idea what might be the Radius server keeps flapping?

The radius source interface is Loopback 0

Regards,

OJ

I read some where when the Deadtime is not config then the Radius Server flap Dead/alife so just config the Dear Time and see the result.

Do you mean the following command?

radius-server deadtime xxx

Did that command fix your issue? What values did you use to correct this?
