802.1x/EAP Switch Authentication
¥ 802.1x and EAP (Extensible Authentication Protocol) can
authenticate a device before allowing access to a switch
and can assign a VLAN after authentication
EAP allows different authentication types to use the same format
(TLS, MD5, OTP)
¥ Works between the supplicant (client) and the
authenticator (network device)
¥ Maintains backend communication to an authentication
(RADIUS) server
¥ The authenticator (switch) becomes the middleman for
relaying EAP received in 802.1x packets to an
authentication server by using RADIUS to carry the EAP
information
¥ Available on Cat 2900,4K,6K in CatOS 6.2; Cat 3550 in
12.1(4)EA1; Cat 2950 in 12.1(6)EA2
