This section describes how to configure a user to remotely log in to devices through Telnet to perform management and maintenance.
If one or more devices need to be configured and managed, you do not need to connect each of the devices to the user terminal for local maintenance. If you have obtained the IP addresses of the devices and it is not the first time for you to log in to the devices, use Telnet to log in to the devices from the user terminal and perform remote device configuration. This method allows you to maintain multiple devices using a single user terminal, greatly facilitating operations.
Device IP addresses must be preconfigured through the console port.
You are advised to use STelnet because Telnet is insecure.
