10.1 Connecting to a Cisco device

It is important to understand how to connect to a Cisco device, both in a real-world situation and within the simulation tools available in this course. In the real world, Cisco devices do not have web interfaces or easy configuration screens. The configuration changes are made via a command-line interface (CLI) that is accessed via a terminal emulation client. Watch the video below (which is about 4 minutes long) to see how to connect to Cisco devices using a console connection or remote access methods.
