We are using Radius server feature and install radius function on one of the Aerohive switches on site as attached as "Capture-radius.png". Every time an end device is being authenticated, there are two situations we have noticed from the log files. One is if the device is authenticated in 20 seconds there is no ping drops at all. if more than 20 seconds, 3 time ping drops will be seen and also the end device will be dropped from the network as well as attached as "Capture-radius-2.png".

Thank you for reaching out, I have a few questions to get a better idea of the scope of the issue.

 

Are you attempting to ping the Radius server from the AP or a client device?

Do the pings ever get through?

Could you tell me if you have ICMP disabled on your network?

Also, if you go to Configure> Open the network policy in use> Go to Additional Settings> Device data Collection and Monitoring (left hand side menu)> Scroll down to the Automatic Synthetic Traffic Generation> Can you tell me if either option in this section is enabled?

Finally could you tell me what kind of Radius we are using? Is it hosted on the AP or externally on your backend network?
