◆
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 login 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.
