Moxa Managed Ethernet Switch (UI_2.0_FW_5.x) User Manual
Authentication
Login Authentication
Moxa switches provide three different user login authentications: TACACS+ (Terminal Access Controller
Access-Control System Plus), RADIUS (Remote Authentication Dial In User Service), and Local. The
TACACS+ and RADIUS mechanisms are centralized “AAA” (Authentication, Authorization and Accounting)
systems f or connecting to network services. The f undamental purpose of both TACACS+ and RADIUS is to
provide an ef f icient and secure mechanism f or user account management.
There are five combinations for users:
1. TACACS+, Local: Check TACACS+ database f irst. If the TACACS+ server is not reachable, then the
switch will check the local database.
2. RADIUS, Local: Check RADIUS database first. If the RADIUS server is not reachable, then the switch
will check the local database.
3. TACACS+: Only check TACACS+ database
4. RADIUS: Only check the RADIUS database
5. Local: Only check the Local database
