RADIUS

Hi guys,

its my first attempt of creating RADIUS which is already installed on a windows server R2 standard edition.
I then configure this on a cisco switch, but no luck as to how its supposed to work and authenticate any ideas

you should start with the following instructions if you are using NPS as your radius server. https://docs.microsoft.com/en-us/windows-server/networking/technologies/nps/nps-manage-install

you then need to setup your policy, dictionary, authenticator and shared secret definitions on NPS.

Hi Brain

I have all of it set up.

But I am failing with how it does authenticate

Next make sure the shared secret is setup between NPS and the switch. You should then try to ssh/telnet into the switch. Then check the NPS Appplication log to determine if the request if making it to NPS and what NPS is doing with it.

I think the main issue is that you use a switch from Cisco instead of Extreme Networks.

That should cover it all...

The first link in the list looks promising - I haven't configured a C in a long time.

You can always go to your event viewer and see why NPS is failing.

The event log will tell you exactly why its failing. That will point you in the right direction. Also, your infrastructure is somewhat vaguely described--What part of the system is using Enterasys/Extreme Networks? Or is this a random "how to get NPS to work with Cisco" thread?

You also didn't describe the authentication mechanism--MAC auth, LDAP, 802.1x, ect... If you go into more detail we can probably address your problem more specifically.
