Disable RADIUS testing

[AhmedJawad]

Hi All, 

  what will be the impact on disabled Radius testing? how the switch will know when the ISE is unreachable, 

[Brash]

RADIUS testing polls the RADIUS server once every 24 hours to verify that it's online and serving requests.

Disabling it means that you lose the alerting to indicate that the Meraki device cannot reach the RADIUS server.

By doing so , you loose the ability to failover on a second configured RADIUS server , right ?

Guess not. Once every 24 hours for polling would not be a good failover method

Afaik it always uses radius 1, if no response it going to use 2,  and then 3 etc

[RaphaelL]

So the RADIUS testing is not intented for a failover mecanism , but to alert you that it is not responding

If it tries to authenticate against a RADIUS server which is down you have to wait for it to timeout before trying the next RADIUS server.  The user may see this is taking longer before their machine can access services on the network.
