Application Scenarios for 802.1X Access

Application Scenarios for 802.1X Access

Typical Applications of 802.1x Access

The networking mode for 802.1x access is similar to that for IPoE, IPoEoV, and IPoEoQ. An EAP packet is converted into an EAPoL packet after passing through an Ethernet interface on a PC. The EAPoL packet can arrive at the BRAS directly or arrive at the BRAS after being added with a VLAN tag on a LAN switch or being encapsulated through AAL5 on a DSLAM.

By decapsulating the packet and identifying the VLAN tag, the BRAS obtains information such as the physical information about the user, user name, and password. In this manner, the BRAS prepares data for user access authentication.

Figure 7-5 is a typical networking diagram for 802.1x access. As shown in this diagram, the user packet arrives at the BRAS directly.

Figure 7-6 is a networking diagram for 802.1XoEoV access. As shown in this diagram, the user packet is sent to the BRAS for authentication after being added with a VLAN tag on the switch.

Figure 7-7 is a networking diagram for 802.1XoEoQ access. As shown in this diagram, the user packet is sent to the BRAS for authentication after being added with VLAN tags on two switches.
