LABEL DESCRIPTION
State Select Enable to permit 802.1x authentication on the Switch.
Note: You must first enable 802.1x authentication on the Switch
before configuring it on each port.
Authentication
Method
Select whether to use Local or RADIUS as the authentication method.
The Local method of authentication uses the “guest” and “user” user
groups of the user account database on the Switch itself to authenticate.
However, only a certain number of accounts can exist at one time.
RADIUS is a security protocol used to authenticate users by means of
an external server instead of an internal device user database that is
limited to the memory capacity of the device. In essence, RADIUS allows
you to validate an unlimited number of users from a central location.
Primary Radius
Server
When RADIUS is selected as the 802.1x authentication method, the
Primary Radius Server will be used for all authentication attempts.
IP Address Enter the IP address of an external RADIUS server in dotted decimal
notation.
UDP Port The default port of a RADIUS server for authentication is 1812.
Shared Key Specify a password (up to 32 alphanumeric characters) as the key to be
shared between the external RADIUS server and the Switch. This key is
not sent over the network. This key must be the same on the external
RADIUS server and the Switch.
Second Radius
Server
This is the backup server used only when the Primary Radius Server is
down.
