The access device supports the following modes:
Multicast trigger mode—The access device multicasts Identity EAP-Request packets periodically (every
30 seconds by default) to initiate 802.1X authentication.
Unicast trigger mode—Upon receiving a frame with the source MAC address not in the MAC address
table, the access device sends an Identity EAP-Request packet out of the receiving port to the unknown
MAC address. It retransmits the packet if no response has been received within a certain time interval.
802.1X authentication procedures
802.1X authentication has two approaches: EAP relay and EAP termination. You choose either mode
depending on the support of the RADIUS server for EAP packets and EAP authentication methods.
EAP relay is defined in IEEE 802.1X. In this mode, the network device uses EAPoR packets to send
authentication information to the RADIUS server, as shown in a.
a. EAP relay
In EAP termination mode, the network access device terminates the EAP packets received from the client,
encapsulates the client authentication information in standard RADIUS packets, and uses Password
Authentication Protocol (PAP) or Challenge Handshake Authentication Protocol (CHAP) to authenticate to
the RADIUS server, as shown in b.
