Authentication Sequence
– 223 –
◆
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.
Example
Console(config)#authentication enable radius
Console(config)#

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.
