Naganathan, any station that wants to communicate to a Radius server must be registered as a client in the Radius server. And for every client, the Radius server will have a shared secret (think of it as a password) to validate that the client i the correct one.
So, you will need two enter commands in the switch:
configure radius netlogin primary server 192.168.1.74 client-ip 192.168.1.4 vr "VR-Default"
configure radius netlogin primary shared-secret "
mysecret" (you can select a different one...)
And then you will need to add the switch as a client in NPS.
I nthe Windows server open
NPS, open
Radius Clients and Servers, select RADIUS Clients, right-click and select
New:
In the New RADIUS Client form input the switch address (192.168.1.4) in the
Address field. Then enter the shared secret (
mysecret, or whatever you chose in the previous command) in the
Shared Secret and
Confirm Shared Secret fields. Press OK to save. The new client should appear in the clients list.
Now the switch and the Radius server are ready to talk to each other.
