Remote Authentication Dial-in User Service (RADIUS) and Terminal Access
Controller Access Control System Plus (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 switch.
Figure 134: Authentication Server Operation
RADIUS uses UDP while TACACS+ uses TCP. UDP only offers best effort
delivery, while TCP offers a connection-oriented transport. Also, note that
RADIUS encrypts only the password in the access-request packet from the
client to the server, while TACACS+ encrypts the entire body of the packet.
