Configuring LDB
If your switch is not enabled with an advanced authentication method, like RADIUS, for authentication,
you can use the local database (LDB) feature to perform local authentication (port-based
authentication).After the switch is enabled with the LDB feature and related access rights are
configured, a user trying to access an address through the switch will be authenticated. After successful
authentication, the switch allows the user to use the corresponding port. Otherwise, the port is blocked.
Configuring LDB Parameters
On this page, you can enable or disable the LDB feature and configure the global LDB parameters.
Click Security > LDB > Setup. The LDB Setup Page opens.
