Command Usage
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.
RADIUS and TACACS+ logon authentication assigns a specific privilege level for each user name and password pair. The
user name, password, and privilege level must be configured on the authentication server.
You can specify three authentication methods in a single command to indicate the authentication sequence. For example,
if you enter "authentication enable radius tacacs local," the user name and password on the RADIUS server is verified first.
If the RADIUS server is not available, then authentication is attempted on the TACACS+ server. If the TACACS+ server is
not available, the local user name and password is checked.
Example
Console(config)#authentication enable radius
Console(config)#

5.12.3 RADIUS Client

Remote Authentication Dial-in User Service (RADIUS) is a logon authentication protocol that uses software running on a central
server to control access to RADIUS-aware devices on the network. An authentication server contains a database of multiple
user name/password pairs with associated privilege levels for each user or group that require management access to a switch.
