Enabling the Telnet Service

GUI: Access the Graphical User Interface (GUI).

1. Navigate to the System tab in the bottom-left corner of the GUI.

2. Enable the Telnet service on the default port.

System > Telnet Server> Enable

Enabled: checked
Port: 23

The CLI equivalent of this configuration is shown next.

CLI: Access the command line interface (CLI). You can do this using the CLI button in the GUI or by using a program such as PuTTY.

1. Enter configuration mode.
