What does ReAuthEnabled on Dlink switch mean?


first, please see the attached image.

What does ReAuthEnabled under 802.1x tab means?
I know what is 802.1x.
Ii noticed that many of clients connected to that switch frequently facing a network disconnect problems, i have to disable/enable NIC adapter in order to re connect, can ReAuthEnabled  help me in my case?

Thank you.

ReAuth is simply used to have 802.1x periodically reauthenticate the port.
It might help you would with your timeout issue.

Thank you for you response.

so if I disabled it, the port will authenticate one time, right ?

if the machine connected to that port ( already authenticated), will the port disable the port until it will authenticate again ?
Yes if it is disabled it will only auth one time.

thank you, you answered my first question.

but I think my second question was not clear.

I meant will the switch authenticate one time per machine (connected to port) or one time for all machines connected to that port ?

thank you again.
That is ultimately is defined by whether or not 802.1x is running in single or multi mode.
If it's single mode (which if memory serves is port mode on D-Link) then it would authenticate whatever is connected to the port, if its multi/mac address mode then it would auth all the hosts connected once.
