802.1x security mode
IEEE 802.1x is a proposed standard that provides a means to authenticate and authorize network devices attached to a LAN
port. A port in the context of IEEE 802.1x is a point of attachment to the LAN, either a LAN jack for the case of a desktop PC,
or a laptop PC association with an Access Point device.

There are three main components in the authentication process. The standard refers to them as:
1.
supplicant (client PC)
2.
authenticator (Access Point)
3.
authentication server (RADIUS server)
When using 802.1x Security Mode or Mixed mode (802.1x and WEP), you need to configure your Radius server for
authentication purposes.
Initially the unauthenticated client PC cannot send any data traffic through the HP WL520 device to other systems on the LAN.
Data traffic is always encrypted with a WEP key that the client PC receives after it has been authenticated. The HP WL520
device inhibits all data traffic from a particular client PC until the client PC is authenticated. Regardless of its authentication
status, a client PC can always exchange 802.1x messages in the clear with the HP WL520 unit.
The HP WL520 device acts as a pass-through device to facilitate communications between the client PC and the RADIUS
server. The HP WL520 unit and the client PC exchange 802.1x messages using an EAPOL protocol. Messages sent from the
client station are encapsulated by the HP WL520 device and transmitted to the RADIUS server using EAP extensions.
Upon receiving a reply EAP packet from the RADIUS, the message is typically forwarded to the client PC, after translating it
back to the EAPOL format. Negotiations take place between the client PC and the RADIUS server. In case of success, the
RADIUS server sends a per-session key to the HP WL520 device.
NOTE:
Currently, only the EAP type of EAP-TLS (smart card or certificate) is supported when using 802.1x security mode
only. In mixed mode, both the EAP-TLS and EAP-MD5 types are supported provided that the RADIUS server is also
configured to support both types.
