• RADIUS uses UDP while 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
encrypts the entire body of the packet.
• RADIUS and logon authentication control
management access via the console port, Web browser, or
Telnet.
• RADIUS and logon authentication assign a specific
privilege level for each user name/password pair. The user
name, password, and privilege level must be configured on the
authentication server.
• You can specify up to three authentication methods for any
user to indicate the authentication sequence. For example, if
you select (1) RADIUS, (2) TACACS and (3) Local, the user
name and password on the RADIUS server is verified first. If the
RADIUS server is not available, then authentication is attempted
using the server, and finally the local user name and
password is checked.
