3Com 3CBLSF26H manual Configuring LDB Parameters

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.
