4.1.7 802.1X
802.1X provides port-based authentication, which involves communications
between a supplicant, authenticator, and authentication server. Port refers to a
single point of attachment to the LAN infrastructure. The supplicant is often
software on a client device, such as a laptop; the authenticator is a network
device, such as an Ethernet switch or wireless access point; and the authentication
server is typically a host running software supporting the RADIUS and EAP
protocols.
Port-based network access control (PNAC) ensures that all users are authorized
before being granted access to the network. User authentication is carried out
using any standard-based RADIUS server.
802.1X Configuration
• Mode: Enables or disables 802.1X globally for all ports on the switch. The
802.1X protocol must be enabled globally for the switch before the port settings
are active. (Default: Disabled)
• RADIUS IP: Address of authentication server.
• RADIUS UDP Port: Network port of authentication server used for
authentication messages. (Range: 1–65535; Default: 1812)
• RADIUS Secret: Sets the text string used for encryption between the switch and
the RADIUS server. This key is used to authenticate logon access for the client.
Do not use blank spaces in the string. (Maximum length: 48 characters)
