Hi,
Thanks for the quick reply.

As from hostapd documentation, it is said that it can be used as a standalone Wireless AP.
But you have mentioned below:
"build  your own switch using hostapd".
Can it also be used as a standalone EAP- SIM Server/authenticator (sort of switch) which is working on "eth0" port? Right?
If it is so, on the wireless LAN, wpa_supplicant scans the AP by SSID. On the wired lan, how can the wpa_supplicant can point to some particular switch (actually hosted by hostapd). Does wpa_supplicant also receives any input regarding ip address of authenticator as we have for eapol_test which takes the IP address of AAA Server?

Any pointer to this?

BR,
AAMER

You can use wpa_supplicant for wired IEEE 802.1X authentication, so if
you have a suitable authenticator (likely some kind of managed switch or
build your own using hostapd), you can use that to run EAPOL/EAP
authentication over wired ethernet. Alternatively, preauth_test could be
used to do this using the RSN pre-authentication ethertype instead of
EAPOL, but the end result is more or less the same.
