CISCO CDP basics discovery protocol data link layer 2
CISCO CDP basics - serial port settings, clock rate, show cdp neighbor detail entry, changing cdp timer, and holdtime. In this video... you will notice I actually make a small "mistake". I label 'Router4' as R2.... or (Router2) and you can see/hear the confusion I go through as I realize (later) I had mis-Labeled this router. WHY did I leave this alone??? WHY ... did I not edit this "out"? BECAUSE... this is EXACTLY the type of mistake that YOU will make, as you begin your own training. This is EXACTLY the "simplest" kind of mistake (among MANY 'small' mistakes) that you will make in your long .... LONG "career" of Information Technology support. IF... you are "new" to I.T. re-Listen to this again, and LISTEN to what I am saying (out loud) as I retype the name of Router 4... (incorrectly) as "Router2"... this is exactly, the "type" of mistake you will make, in real life. In MY case (on this video) I did not consciously realize the mistake until you hear me pause and say "INTERESTING"... then I realized, I named R4 as R2... and I was confused for a moment. But I also realized this was an EXCELLENT example of a "real mistake" to SHOW You.....

...and you will not even REALIZE you have made the mistake... as you are MAKING the mistake... we can only TRY to be vigilant, and we combat these errors, by instilling, and practicing our craft, in DISCIPLINED fashion... I left it in, b/c this was a true example of the momentary "confusion" you can go through over a "small" mistake. I leave it here, to exemplify and WARN you of the types of mistakes you will make on quizzes (or CCNA exams) or A+ exams.... etc.... you will actually SIT THERE.... "befuddled".... (often) and it will be 'Because of' ... a "small" mistake you made. you will lose points, you will lose face, and you WILL at some point in your career, ALWAYS, Always, always.... be forced to apologize.... for an "error" you have made. Because you are HUMAN. We all strive for perfection. Very few of us ARE "perfect".
