The set protocols dot1x interface auth-mode 802.1x command enables the 802.1X authentication mode on a specified interface.
set protocols dot1x interface <interface-name> auth-mode 802.1x
Specifies the physical interface name. The value could be ge-1/1/1, xe-1/1/2, and so on.
When no NAC authentication mode and the CLI command set protocols dot1x interface <interface-name> are configured, the port is open to the user; but if the CLI command set protocols dot1x interface <interface-name> is configured, the port becomes blocked.
802.1X authentication is an authentication method that controls the network access rights of users based on ports together with the MAC address of client. The Extensible Authentication Protocol (EAP) packet is used to exchange authentication information between the supplicant, authenticator and authentication server. This technology is mainly used in networks with high security requirements. 802.1X authentication requires 802.1X client software to be installed on the supplicant.
- Enable 802.1X authentication mode on interface ge-1/1/1.
