Cisco CCNA Video Training:

Troubleshooting The Line Protocol

By Chris Bryant, CCIE #12933

During your CCENT and CCNA studies, you're introduced to something called the "line protocol", which reflects the logical state of the interface.

The good news? The line protocol's either up or down.

The bad news? There are quite a few different reasons the line protocol can be down!

In this Cisco training video, I'll show you how the line protocol should look, and how to troubleshoot a line protocol that doesn't look as it should!

I've got quite a few more CCNA videos for you on my Cisco certification video page, where I've got almost a dozen videos for you to watch now and dozens more to be posted in March 2009 alone!
