problem with RADIUS authentification

[danmer1992]

Hello guys, i have problem with RADIUS authentification. 
I pass successful authentication on the switch, but after 5 minutes I am thrown out. If you do "clear arp", then the problem disappears and you can log in again, but the problem repeats. What can you try to fix this problem?

Our switch HPE ProCurve 6120XG.

Thanks for advance

Hi @danmer1992 

Is there any 'idle-timeout ...' value configured on the swtich under 'line vty' mode. What is the radius server and what are the logs on the server saying regarding the session disconnection.

Hi @drk787 ,

Yes,maybe You trued. but in my opinion Blade 6120 haven't option "line vty".
Today I was looking for how to configure myself an option but unfortunately I could not find it.

Do you know how to change it?

Thanks for advance

And I did not find any logs on a switch not on the server radius.

And after i see next error:

I 03/26/21 18:47:31 00421 radius: Can't reach RADIUS server 10.207.50.5
W 03/26/21 18:47:31 00419 auth: Invalid user name/password on SSH session

Do you see any reachability issue to the Radius server when your login fails
