Command Usage
•
By default, management access is always checked against the
authentication database stored on the local switch. If a remote
authentication server is used, you must specify the authentication
sequence and the corresponding parameters for the remote
authentication protocol.
•
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. These access
options must be configured on the authentication server.
•
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 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) 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.
