Hi,<br>I am planning to use wpa_supplicant and hostapd on the wired LAN for EAP-SIM testing. For that, I have referred to the below community chat:<br><br><a href="http://lists.shmoo.com/pipermail/hostap/2006-January/012537.html">http://lists.shmoo.com/pipermail/hostap/2006-January/012537.html</a><br>
<br>Here the wpa_supplicant is used as EAP-Peer while the hostapd as AAA Server but in the middle the Cisco Switch is used as authenticator.<br>For that, the below mentioned configuration is used:<br><br><pre>CONFIG_IEEE8021X_EAPOL=y
CONFIG_EAP_MD5=y
CONFIG_EAP_MSCHAPV2=y
CONFIG_EAP_SIM=y
CONFIG_PCSC=y
CONFIG_DRIVER_WIRED=y
CONFIG_BACKEND=file
CONFIG_CTRL_IFACE=y
<span style="background-color:rgb(255,153,0)"><font><b>CONFIG_CTRL_IFACE_UDP=y</b></font></span>
</pre><br>Normally the EAPOL packets are transported between authenticator and supplicant and they are encapsulated within Ethernet frames directly. Now from the above parameter, are we changing the control interface to UDP over which the EAPOL packets are encapsulated first or what? In the wpa_supplicant and hostapd, is it possible to send the eapol packets over UDP between EAP-Peer and authenticator ?<br>
<br>Secondly, is it possible to use the hostapd as switch (authenticator) instead of real switch for EAP-SIM testing over wired LAN. From the documentation, it can be guessed that hostapd can be configured as standalone switch as well. Did anybody try that so far?<br>
<br>wpa_supplicant (EAP-SIM supplicant) <----> hostapd (authenticator + AAA Server)<br><br>Any details will be appreciated.<br><br><br>BR,<br>A.Chaudry<br><br><br><br><br>
