Dell S4048T User Manual

802.1X
802.1X is a port-based Network Access Control (PNAC) that provides an authentication mechanism to devices
wishing to attach to a LAN or WLAN. A device connected to a port that is enabled with 802.1X is disallowed
from sending or receiving packets on the network until its identity is verified (through a username and
password, for example).
802.1X employs Extensible Authentication Protocol (EAP) to transfer a device’s credentials to an
authentication server (typically RADIUS) using a mandatory intermediary network access device, in this case, a
Dell Networking switch. The network access device mediates all communication between the end-user
device and the authentication server so that the network remains secure. The network access device uses
EAP-over-Ethernet (EAPOL) to communicate with the end-user device and EAP-over-RADIUS to
communicate with the server.
NOTE
: The Dell Networking Operating System (OS) supports 802.1X with EAP-MD5, EAP-OTP, EAP-TLS,
EAP-TTLS, PEAPv0, PEAPv1, and MS-CHAPv2 with PEAP.
