Device Configuration Modes

Users can log in to the device for configuration and management in different modes. (For details of the login modes, refer to the chapter "System login" in the configuration guide.) The device provides four typical configuration modes:

• Logging in to the device locally through the Console port. By default, users can configure the device directly in this mode.
• Logging in to the device by remote dial-up through a Modem. The device cannot be configured directly in this mode. That is, before configuration, some preparations need to be made.
• Logging in to the device remotely through Telnet. The device cannot be configured directly in this mode. That is, before configuration, some preparations need to be made.
• Logging in to the device remotely through SSH. The device cannot be configured directly in this mode. That is, before configuration, some preparations need to be made.
