LABEL DESCRIPTION
Authentication Server
IP Address Enter the IP address of the external RADIUS server in dotted decimal notation.
UDP Port The default port of the RADIUS server for authentication is 1812. You need not
change this value unless your network administrator instructs you to do so.
Shared Secret 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.
Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch
loses these changes if it is turned off or loses power, so use the Save link on the top
navigation panel to save your changes to the non-volatile memory when you are
done configuring.
Cancel Click Cancel to reset the fields.
