Benefits
Limitations
EAP termination
Works with any RADIUS server that
supports PAP or CHAP authentication.
 Supports only MD5-Challenge
EAP authentication and the
"username + password" EAP
authentication initiated by an
iNode 802.1X client.
 The processing is complex on
the network access device.
EAP relay
Figure 31 shows the basic 802.1X authentication procedure in EAP relay mode, assuming that EAP-MD5
is used.

1. When a user launches the 802.1X client software and enters a registered username and password,
the 802.1X client software sends an EAPOL-Start packet to the network access device.
2. The network access device responds with an Identity EAP-Request packet to ask for the client
username.
