Configuring AAA for Administrative and Local Access Overview D-Link Mobility System Software (MSS) supports authentication, authorization, and accounting (AAA) for secure network connections. As administrator, you must establish administrative access for yourself and optionally other local users before you can configure the DWS-1008 switch for operation. Here is an overview of configuration topics: 1. Console connection - By default, any administrator can connect to the console port and manage the switch, because no authentication is enforced. D-Link recommends that you enforce authentication on the console port after initial connection. 2. Telnet or SSH connection - Administrators cannot establish a Telnet or Secure Shell (SSH) connection to the switch by default. To provide Telnet or SSH access, you must add a username and password entry to the local database or, optionally, set the authentication method for Telnet users to a Remote Authentication Dial-In User Service (RADIUS) server. 3. Restricted mode - When you initially connect to the switch, your mode of operation is restricted. In this mode, only a small subset of status and monitoring commands is available. Restricted mode is useful for administrators with basic monitoring privileges who are not allowed to change the configuration or run traces. 4. Enabled mode - To enter the enabled mode of operation, you type the enable command at the command prompt. In enabled mode, you can use all CLI commands. Although MSS does not require an enable password, D-Link highly recommends that you set one. 5. Customized authentication - You can require authentication for all users or for only a subset of users. Username globbing allows different users or classes of user to be given different authentication treatments. You can configure console authentication and Telnet authentication separately, and you can apply different authentication methods to each. For any user, authorization uses the same method(s) as authentication for that user. 6. Local override - A special authentication technique called local override lets you attempt authentication via the local database before attempting authentication via a RADIUS server. The switch attempts administrative authentication in the local database first. If it finds no match, the switch attempts administrative authentication on the RADIUS server.
