Overview of User Authentication
It is allowed to configure the Managed Switch to authenticate users logging into the system for management access using local
or remote authentication methods, such as telnet and Web browser. This Managed Switch provides secure network
management access using the following options:
„ Remote Authentication Dial-in User Service (RADIUS)
„ Terminal Access Controller Access Control System Plus (TACACS+)
„ Local user name and Priviledge Level control
RADIUS and TACACS+ are logon authentication protocols that use software running on a central server to control access to
RADIUS-aware or TACACS-aware devices on the network. An authentication server contains a database of multiple user
name / password pairs with associated privilege levels for each user that requires management access to the Managed Switch.
