13.6 RADIUS
RADIUS (Remote Authentication Dial-In User Service) authentication is a popular protocol
used to authenticate users by means of an external server instead of (or in addition to) an
internal device user database that is limited to the memory capacity of the device. In essence,
RADIUS authentication allows you to validate an unlimited number of users from a central
location.

at a time. By default the switch uses the first configuration file (with an index number of 1).
You can set the switch to use another configuration file.
Use the Boot Config screen to select which configuration file you want the switch to use after
the next system reboot.
