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 authentication server. The encryption methods used for the
authentication process must also be configured or negotiated between the authentication server and logon client. This switch
can pass authentication messages between the server and client that have been encrypted using :
„
MD5 (Message-Digest 5) ,
„
TLS (Transport Layer Security)
„
TTLS (Tunneled Transport Layer Security).
•
You can specify up to three authentication methods for any user to indicate the authentication sequence. For example, if you
select (1) RADIUS, (2) TACACS 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.
