default login.
Figure 85. RADIUS Servers in a DWS-3000 Network
When a user attempts to log in, the switch prompts for a username and password. The switch
then attempts to communicate with the primary RADIUS server at 10.10.10.10. Upon
successful connection with the server, the login credentials are exchanged over an encrypted
channel. The server grants or denies access, which the switch honors, and either allows or does
not allow the user to access the switch. If neither of the two servers can be contacted, the
switch searches its local user database for the user.
