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 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.
