switches to Local Authentication when there is no
reply from the RADIUS server(s) after three
attempts. For more information, see “Setting Up
Fallback” on page 3-12.
Setting Up TACACS+ Authentication
Under TACACS+ authentication, a username/password
combination is validated against the TACACS+ user and client
database. The TACACS+ security database is stored on the
TACACS+ server for the LX unit. In order to use TACACS+
authentication on a port, you must have TACACS+ set up for the
LX unit. See “Setting Up TACACS+” on page 2-25 for
information about setting up TACACS+ on the LX unit.
