I genuinely appreciate Keith, Chuck, and Jeremy. This is my second time reviewing CCNA now, first time was a cohort, which was amazing but I was as green as it gets so it was a struggle for me, especially at age 38 (then), heck, I didn't even know what a "ping" was. I was always a lover of tech and was a true nerd also but I spent most of my time as an infantryman in the Army. I finally was discharged and wanted to be a network guy so I went to school for it, finished the cohort but failed my CCNA. I ended up taking a help desk job and eventually landing a darn good gig, life was good and then I lost my job so I have now decided to try for my CCNA again and this time, watching the videos and taking out a monthly subscription to CBT Nugs it all makes much more sense. I'm grateful to receive this knowledge. Thanks

Another reason you might want to do tag (trunk) is for scalability. For example, if you want to pass VLAN traffic between the switches without tagging (trunking), you would have to run the physical cable between switches for each VLAN. For example, if you have 10 VLANs, you would end up running 10 physical cables. With trunking an interface on a switch, you can achieve the same goal with just one physical link because it will tag a VLAN id before sending a frame with appropriate VLAN id so the receiving switch knows that which VLAN a frame belongs to. In future, if you introduce more VLANs in your network, you can simply just create VLANs in switches and trunk it without any physical work.

Your lessons are a blessing, I haven't found a singel teacher which illustrates as well as you. The fact that you draw as you lecture helps alot! You're also so goofy and cool! Keep up the great work!

I'm speaking it into the youtube-verse now. I told my girlfriend my plan and now i'm telling....all of you :) I have spent waaayyyy too long trying to "study" for the CCNA. I just don't ever feel ready enough and taking the Alphaprep always sets me back because it makes me think I don't know anything. I went through Neil Anderson's courses and labs about 2x by now but it's always spaced out the time that I dedicate to study. So I am declaring that once I make my way through Keith's AMAZING CCNA Master Playlist and labs, I'll go through Neil's labs again and then I will take the exam...it's now or never :') Thank you for all your help and motivation Keith.

I not only enjoyed this video, I actually learned a lot which was the most important thing. I watched this specifically to supplement learning VLAN Trunking and I learned enough to say I understand. The Cup Props was AMAZING to convey the actuality of things. The only thing you did not show was an actual physical demonstration of how the switches are connected in a Trunk Switch to Switch. But i get the idea now. I was always confused as to why there was two physical cables connected for the Trunking. I think it dawned on me finally when you did "show Interface trunk" and in the last section info i think i understood now that STP is actually working on one the loop connections. If i'm incorrect please let me know. Too bad i didn't get CBTN validation credits for watching 42 mins of this video.

As a side note. We really should set the switchport mode on all ports, especially the ones, we don't want to use as trunk ports. Otherwise an attacker, could connect to a port, and have switch set it self to trunk. And have access to all VLANS.

Hey Keith. Say in a scenario where it’s a PTP trunk link with a repeater Switch in the middle due to non line of sight. When you setup a LAG 1 between a main and redundant link and you need to setup a LAG 2 group that essentially for the repeater side, is there anything to keep in mind or will the packets just flow through load balanced path?

@KeithBarker

Great question. Much of that will depend on the type/function of that repeater switch. You may need to use QinQ tunneling if that repeater switch tries to think to much outside of keeping the individual connections/links isolated. Here is a resource for more on QinQ: www.cisco.com/c/en/us/td/docs/routers/access/ISRG2/software/feature/guide/QinQ_L2PT.html Hope that helps, and thanks for the question.

Very Nice work. But I'm wondering, in your example, vlan 10 and vlan 20 are on different physical switches and you use a trunk between them. But would you use a trunk if vlan 10 and vlan 20 were on the same physical switch?

when we say switches filter packets? Shouldn't it be switches filter frames as switches operate at level 2 and at level 2 we refer to data as frames?

you remind me of Steve-O.

How were u able to capture the packets btwn the switches tho?

Keith, when you say "Don't count on it happening dynamically', it sounds like that is a possibility but the best practice is to designate trunk ports specifically, yes?
