- When we're troubleshooting a Cisco device,
we access those devices physically by using the console port
or remotely by using VTY lines.
In this lesson, we're going to look at ways
we can identify and troubleshoot issues
related to console and VTY line access,
and we'll examine some remote access protocols.
We'll also be taking a look at protocols
such as SSH, Telnet, and TFTP, which are necessary
when copying files and iOS images to and from a router.
