3-12 Setting Up RSA SecurID Authentication
LX Series Configuration Guide
Setting Up RSA SecurID Authentication
Under RSA SecurID authentication, a username/
password combination is validated against the
RSA SecurID user and client database. The RSA
SecurID security database is stored on the RSA
SecurID server for the LX unit. In order to use
RSA SecurID authentication on a port, you must have RSA
SecurID set up for the LX unit.
See “Setting Up RSA SecurID” on page 2-33 for information
about setting up RSA SecurID on the LX unit. RSA SecurID
authentication is disabled by default on console ports.
X
To enable RSA SecurID authentication on a console port
1. Access the Asynchronous Command Mode for the
asynchronous port to configure.
2. Execute the following command to enable RSA SecurID
authentication on the port:
Example Async5:0 >>authentication outbound rsa
securid enable
L If RSA SecurID authentication is enabled, you may
want to implement a backup method (Fallback),
which will be used if the RSA SecurID server is
unreachable. Fallback switches to Local
Authentication when there is no reply from the RSA
SecurID server(s) after three attempts. For more
information, see “Setting Up Fallback”.
Setting Up Fallback
Fallback Authentication can be used as a mechanism for
authenticating users when the configured authentication method
(such as LDAP, RADIUS, TACACS+, or RSA SecurID) fails
because the authentication server is unreachable. When a user
logs in by using Fallback, his or her username/password
combination is validated against the LOCAL security database
for the LX unit.
PPP CHAP is not
supported with
authentication
SecurID.
