external authentication options and/or the local user database.

The first authentication method that the IOLAN attempts. 
Data Options: Local, RADIUS, Kerberos, LDAP, TACACS+, SecurID, NIS

Secondary 
Authentication 
Method
If the 
Primary Authentication Method
 fails, the next authentication method 
that the IOLAN attempts. You can choose to use authentication methods in 
combination. For example, you can specify the 
Primary Authentication 
Method
 as 
Local
 and the 
Secondary Authentication Method
 as 
RADIUS
Therefore, some users can be defined in the IOLAN (

authentication methods are configured, or you will not be able to access the 
IOLAN as the admin user, except through the console port.
