Command Usage
• 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 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 server. If the server
is not available, the local user name and password is checked.
