Day 2! I had quiet a bit of time to think over what I was doing yesterday, and I wanted to improve the quality and speed in which I'm making these videos. I think it's best if I try to talk about each small concept and practice video within 20 minute range. Leaving some room for questions/and ideas in the last 10 minutes. So hoping to keep each feature videos 30 minutes tops!

I ran into an issue in video 2 as you can see. While using the show interface trunk command, if your physical layer is down or the layer 2 is down. The command will respond with no answer. This was a bit troubling, but I guess it's one of the things to remember during the actual exam or out on the real world. I included a few minutes of me troubleshooting this issue, hopefully everyone doesn't get bored.

This was a real good reflection on troubleshooting techniques. You should always remember to look down the layers, making sure each protocol and it's supporting layers are working before examining the issue up the chain. In this case, my physical connections were no set, and my l2 protocol was offline. Which I guess IOS knew, and decided to tell me that if there are no connections, it won't form trunking. Well lesson learned!

Coming up, router on a stick, sub-interfaces quick video!
