combination. For example, you can specify the
Primary Authentication
Method as Local and the Secondary Authentication Method as RADIUS .

The secondary authentication method will be tried only when the IOLAN
cannot communicate with the primary authentication host.

When enabled, the IOLAN will only authenticate the admin user in the local
user database, regardless of any external authentication methods configured.
When disabled, a user called admin must exist when only external
authentication methods are configured, or you will not be able to access the
IOLAN as the admin user, except through the console port.
Default: Enabled
