Session 10: The command-line interface

In previous sessions you have looked at connecting commercial routers and switches together to make a network. This session describes and demonstrates how you can connect to a commercial device in order to view its status and configure it. This session will also introduce the command-line interface (CLI). Through the CLI, a network engineer can monitor, maintain, and configure a commercial networking device.

By the end of this session, you will be able to:

  • understand how a network engineer would connect to a commercial networking device using a console port
  • understand how a network engineer would connect to a commercial networking device using a remote connection via Telnet or SSH
  • identify the different modes within the Cisco CLI
  • configure a hostname and IP address on a Cisco router via the CLI.
