Eli, I know this is an ancient video and you moved on to teaching different stuff loooong ago, but just want to express appreciation of your detailed approach. Your videos really stay in my mind, probably because you repeat what you said in few different ways and go into so much detail. Thanks a lot! Great help for someone with no technical background.
Eli, I'm working on my network+ cert; you've taught me more about switches than TWO semesters at my local college. That speaks volumes for your teaching abilities.
Incredible! I came here getting an understanding of switches and routers as a newbie obtaining detailed info for my Comptia A+ and now I am hooked on your lectures. I am blown away with the knowledge. Thank you very much!
I'm in the process of retraining to become an IT systems technician. Somehow I understand your explanations way easier than my actual teachers explanation in class - I guess bilingual learning is not my thing (german XOR english). Your lessons are detailed and well structured while keeping it relaxed. You do iterations almost always where I need them so I don't have to skip back and forth =) Thank you very very much, sir!
Great to listen to Eli and benefit from his wisdom. He's very kind to be going through all the trouble to produce these lessons. He must have a teacher's heart.
+Jason Wenden go to change adapter settins -> double click your network card (wireless or ethernet) -> configure -> advanced -> Speed & Duplex -> click on Auto Negotiation and select your option
@jgrabener hmmm... it really depends. Generally all modern networking equipment is full duplex. Standard Surveillance cameras using coax cable may or may not be. The PTZ system actually uses a different cable and controller then the video feed for movement. There are PTZ protocols, such as Pelco D, that specify how PTZ cameras operate.

Got a big Job where i have to deploy a huge 20 IP cameras Surveillance System wich involves using Managed Switches, an i have never even touched a Switch before, this video came in very helpful...thank you, i like the warm way you explain, very sintetic
Ahh!! This is so awesome, I love it. I can understand everything at the maximum speed and got to learn this in 20ish minutes. Great content!! Thank you!
I know this is an older video but I have learned more from this guy in the 58 minutes watching this than I did from anything I have ever read on my own. fantastic lessons and looking forward to watching all the others. Thank you from someone who was pushed into handling my office network without having the background to do it!
I just found a solution to one of my problems with my network! I needed to separate the Access Point at my dad's restaurant so that the customers won't be able to see all the other devices in the network. Yeah, I have the same connection for the restaurant and our house so that our customers can have wifi for their devices. Thank you so much dude, keep this awesome work up! ~Valk.
Fantastic! I was trying to learn about switches using CISCO's documents and getting no where. Your explanations are both easy to understand yet have incredible depth. Also your enthusiasm for the subject really shines through and makes the video way more interesting than the subject material would otherwise be. You have my deepest gratitude for your commitment to helping others learn and I wish you the very best in all that life has to offer.
Eli, like always, you have done and are doing a great job. You have heard this over and over. I like reading the comments when I am listing to your presentation. There is one very common thread; you are a great presenter and know how to teach your subject. Thank you again for spending so much of your time to teach us who are not so IT intelligent. I continue to view . . .
Traffic is considerd in a VLAN typically based on ports. Port A can be configured to be in VLAN 10. All traffic entering the port is considered to be in the logical broadcast domain of VLAN 10. Here is a diffrent method. Layer 2 switches/bridges can also consider traffic in a VLAN based on its physical MAC address. If traffic from MAC address 01-01-01-01-01-01 enters on Port A it will be considered in VLAN 10. Now move the end station with that MAC address to Port B on the same switch. The switch will still consider the traffic in VLAN 10.
Thank you SO much for your videos. I was referred by a friend who is a network engineer to watch your videos because I'm starting in the same field. You absolutely did not disappoint!
This is one of the best educational video I have ever seen ... Just after 1 hour of watching this video, my knowledge is at a whole different level now ... yes, I do understand switches a lot better now ... thanks a lot for making this video.
You are incredible Eli. I'm currently interning at a company as an IT tech and even though I've heard about all these things and used some of them in practice; having you explain in baby steps what they do have been incredibly useful to me. You're creating jobs and helping us youngsters out. Thank you again, subbed!
Most switches operate at layer 2 so they won't be packets that are sent there will be frames. I know there are some layer 3 switches as well but...........
Great catch! Eli needs to use the proper terms. He also said that hubs cause broadcast storms. While the congestion may be great and the holdoff times may interfere, that's not a broadcast storm. They are caused by loops in the network. Spanning Tree Protocol is used to stop them. computer.howstuffworks.com/lan-switch13.htm
Also Eeeethernet uses Carrier Sense Multiple Access with Collision Detection (CSMA/CD) en.wikipedia.org/wiki/Carrier-sense_multiple_access_with_collision_detection not CA/CD WHICH DOESN'T EXIST. CSMA/CA is a different protocol often used in wireless networking. en.wikipedia.org/wiki/Carrier-sense_multiple_access_with_collision_avoidance. I can't listen any more to this guy if he is 'teaching' this incorrectly. I spent 25 years in networking and there is nothing wrong with cisco, but there is a lot of other high quality networking gear out there that I've worked with that costs a lot less and is just as good.
You do realize that eli is explaining to people who have no understanding of IT in technical depths. Save your b.s explanation foe your boss and stop being pedantic
Just wanted to let you know, I currently am getting my network+ cert but the problem with these companies cert processes is they expect you to know a lot of terms previously when they start to teach you. Your videos are really helping me understand and connect the dots..LIFE SAVOR!
thank you Eli, I'm getting a revision I would have never got from anyone else, I studied Networking in 2009 and now it's 2016 I haven't got a job in Networking so listening to your lectures keeps me going.
Eli, You're an incredible guy and I thank you, you have educated me faster and more effortlessly than anyone in any technical classroom could ever have! You lay it out once... and it's all crystal clear to me! YOU THE MAN!
Eli Is so good at Computers...You really are a Computer Guy and I am sure you know how to get people instructed about all this stuffs...You make it as easier as possible...Keep it up...You are a star!!!
+Lee Platt Even when Cisco owned Linksys, Cisco was still the better piece of hardware. Personally, I've never considered Linksys "Enterprise" or even "Business" quality.
Eli you are an amazing instructor. watching your videos make my life easy studying computer network at College .keep the hard work up . In hadeth we have this " Stand up for the teacher and glorify him....He could have been a messenger. "
Man i wish my school had teachers like you! I bet you've heard this a million times, but seriously...You make it so easy to understand, not like my dusty old teachers. I tend to search your videos for subjects we've had in class and suddenly, everything is much clearer! thank you very much for these videos!! keep it up :)
The simple explications and definitions in which this guy goes into has been extremely helpful, and has helped very much within my BLANS report for college. Thanks very much !!!
Hi Eli! You are a god send man! Your way of explaining things makes everything simple and easy to grasp! Where were you all these days? I recently found you and since then my knowledge on IT is increasing! Thanx for helping people like me Eli! God bless you! Keep up the good work!
Man you are the best Computer guy on the world you are really know how to introduce IT stuff and how to make it simple to understand . Thank you so much
you are the only guy that explains everything. The good and bad. everyone else just says plug the hub in. I wanted to know if a hub has changes the ip. so I wouldn't affect my home network. And that's why I'm taking your classes. Thanks Eli!
Thank you sir for breaking down switches. I am taking a networking class, and l am currently learning about switches. Reading the textbook, I didn't understand, but with this video I do. You should be a teacher.
I just started to watch some of your videos and you have been awesome. I am an intermediate technology person, and have heard about the different topics you talk about, but I was never able to put them together. They way you put your videos together are now making sense, and one of the examples is how you talk about the portions belong to the ISO Model which I never understood. I know some of these videos are kind of outdated, and new technology is out, but your videos give an outstanding base for understanding from the root tot he top of the tree. You are AWESOME and thank you so much for doing these videos.
Your such a great teacher, I can have your videos playing in the background and minimized and I still get pretty much everything you're saying just from the audio.
A question for the trunk connectors: Why would you need more than one switch? A question for the switches: This video showed the switches in a form of being physically separated from the router, but as it is in my home, I don't have a switch and only a router. Could the functions of the switch possibly be built inside the router? Thanks
very informative video, I am following your networking videos from the very 1st one, this is the 6th one in the list and now I can say you have induced in me, a curiosity to learn more about networking....great work eli!!
Thanks Eli, you give great verbal presentations, I really enjoy your easy listening voice and knowledge. However as a science teacher, your use of the whiteboard, where we see only about one third of it, makes me wonder what do you wish to hide on the other two thirds. Aim for better diagrams. Overall result 9/10. Could work harder. (HaHa)
I ran out of ports on my fiber optic terminal/router so I watched this video to understand switches. Thanks to what I learned in this video I went and bought the correct switch and my setup is running beautifully!
Hi Eli, Found your videos last week and I am addicted to them now ! Information so well explained!! Will recommend these videos to everyone. Thanks once again! Miguel
Great video Eli, very informative! I've had to painfully familiarize with switching in my current job. I thought I had it all figured out, and then they went ahead and developed SDN switches ..
All these sophisticated systems in order to ensure user's comfort! Man, if I was the one who made these things I would just show users a message, at each communication attempt, that says "Make sure the other A-holes in the network are not uploading or downloading anything" and spare myself the trouble!
People praise these people at CBT Nuggets and other places for how well they explain things, and they are good at explaining networking concepts and basics, but damn... I just learned a TOOOON about switches, hubs, VoIP, etc. and it was all clear, precise, and free. This guy will go on as the most underrated networking prof. of all time. I can't thank Eli enough. I'm actually going to check out the personal site now that he is moving away from TH-cam.
Great Videos. Keep it up. 1 thing I have found to be handy is the POE repeater. Using a POE switch, you can drive a POE repeater to run longer than 100Meters.
You're a very informative guy, and I have learnt a lot by watching your channel. Give youtube heaps as you're one of the good guys, and well worth subscribing to. I live in Oz, and have been told Netgear is the best manufacturer for our phone system. I now have what you call fibre cable, here FTTN; Fibre to the Node. Copper from Node to home.
do switches can do router function if this is the case eli..what are the MAIN differences between ROUTER and SWITCHES??thanx your video is plain n simple..great way to understands all the jargons
Thanks for another great video. I was offered a sys admin position despite not having any experience with switches. After watching this it no longer seems like a foreign language to me.
Excellent. The time duration was daunting, but this was a genuinely enjoyable and easy to digest explanation that gave me the information I was looking for AND more. Not to mention leaving me curious about more hardware and software of networking.
Great lesson! I just got a question. How do you connect multiple switches when there are no trunk ports available on them? For example: Small switches. Thanks :D
Thanks. I've gone from watching them as a necessity to just watching them for fun! REASON: They're so simple to learn from and even just running the sound and glimpsing at the screen helps you learn a lot!
Good video to help people understand the basics. One small correction; Ethernet carries it's Data in Frames, rather than packets. Packets don't come into play until you're at layer 3.
Thank you. this was very helpful to me. I will definitely be watching more videos. I am the youth pastor at my church and i have been designated the staff "tech guy". your videos are very knowledgeable and professional.. .
The loop story made my day: i immediately tested it on my 5 port switch and after 30 seconds of faster and faster blinking one of the computer said: no internet access. Magic!
"Ethernet uses something called collision avoidance collision detection in order to send packets." Ethernet uses CSMA/CD (carrier sense multiple access withcollision detection) and 802.11 (WiFi) uses CSMA/CA (collision avoidance). Also Ethernet sends frames, not packets. Other than some subtle technical details this was a great introduction. Thanks for the video.
i wish you a very long healthy life, believe it or not you are really changing lives with this information you take time out to put together. God Bless you!!!
Eli, I know this is an ancient video and you moved on to teaching different stuff loooong ago, but just want to express appreciation of your detailed approach.

Man, you're saving my exam 10 years after uploading the video!😄
Eli, I'm working on my network+ cert; you've taught me more about switches than TWO semesters at my local college. That speaks volumes for your teaching abilities.
i hope this guy makes youtube money, he deserves it
facts
I hope even more he is making money from Cisco...
He is
Eli, I don't have enough words to thank you. The amount of information that you had shared in this video is enormous. GOD BLESS YOU!!!!!
Incredible! I came here getting an understanding of switches and routers as a newbie obtaining detailed info for my Comptia A+ and now I am hooked on your lectures. I am blown away with the knowledge. Thank you very much!
Well done. You make IT sound so easy. I got a promotion from help desk to network analysis and you really help me learn the basics. Thank you
Congrats on your promotion. :)
I know what he is saying is the basics because he says "basically" every 30 secs.
Congrats, Shaun on your promotion! Learning never stops in this field. Best of luck!
Congrats! 3 years past, now I believe your are senior network engineer.
Where were you working when promoted? Still there?
yay so happy for you! i got burned for trying to start help desk career
Man I almost forgot how pure gold you are.
I'm in the process of retraining to become an IT systems technician. Somehow I understand your explanations way easier than my actual teachers explanation in class - I guess bilingual learning is not my thing (german XOR english).

You have great teaching ability.
Thank you for your videos.
eli said "when you have 50 people in an office doing stupid staff""the network may fail!' that comment made my day
@jgrabener hmmm... it really depends. Generally all modern networking equipment is full duplex. Standard Surveillance cameras using coax cable may or may not be. The PTZ system actually uses a different cable and controller then the video feed for movement. There are PTZ protocols, such as Pelco D, that specify how PTZ cameras operate.

best part is you look into the history of where it started.. great.. nice
Can’t believe I actually watched the entire video. It is excellent learning for a newbie !
can you assign a switchport to more than one vlan?
Yes, depending on the vendor, we'd call that a trunk port (Cisco) or a tagged port (various other vendors).
Traffic is considerd in a VLAN typically based on ports. Port A can be configured to be in VLAN 10. All traffic entering the port is considered to be in the logical broadcast domain of VLAN 10. Here is a diffrent method. Layer 2 switches/bridges can also consider traffic in a VLAN based on its physical MAC address.

Hm. Never heard Ethernet pronounced with the first syllable sounding like "Beth" instead of "teeth" before.
I wonder how he pronounces the word "ether".
Or ASUS. 13:07
"company officials told us a few years go that it should be pronounced ah-SOOS". Hmmm. Guess I've been pronouncing it wrong all along.
nevermind. It's supposed to be pronounced AY-soos. I know what, I'll not buy an ASUS so I don't have to worry about pronouncing it incorrectly.
When Eli says it, I hear like a soft "suze". It's rather confusing.
I pronounce it as "ass-oos".
The simple explications and definitions in which this guy goes into has been extremely helpful, and has helped very much within my BLANS report for college.
Thanks very much !!!

Great Videos. Keep it up. 1 thing I have found to be handy is the POE repeater. Using a POE switch, you can drive a POE repeater to run longer than 100Meters.
You're a very informative guy, and I have learnt a lot by watching your channel. Give youtube heaps as you're one of the good guys, and well worth subscribing to. I live in Oz, and have been told Netgear is the best manufacturer for our phone system. I now have what you call fibre cable, here FTTN; Fibre to the Node. Copper from Node to home.
cant stop watching more of your videos. Really helpful. Many thanks man
do switches can do router function if this is the case eli..what are the MAIN differences between ROUTER and SWITCHES??thanx your video is plain n simple..great way to understands all the jargons
Thanks for another great video. I was offered a sys admin position despite not having any experience with switches. After watching this it no longer seems like a foreign language to me.
Excellent. The time duration was daunting, but this was a genuinely enjoyable and easy to digest explanation that gave me the information I was looking for AND more. Not to mention leaving me curious about more hardware and software of networking.
46:10 - 46:48 if it was cisco equipment why would it shutdown? doesn't cisco already has spanning tree protocol like you said?
You are perfectly explain it in simple words that makes complicated terms look so easy and understandable ! Thanks guys
Your videos are exactly what I have been looking for to learn about networking. Thanks a lot
Very great video. Got your videos from my boss, he told me to learn some networking and shizzle and your videos are great. Keep 'em coming.
God bless this guy... I have learned so much without having any networking background
Great lesson! I just got a question.
How do you connect multiple switches when there are no trunk ports available on them? For example: Small switches.
Thanks :D
Thanks. I've gone from watching them as a necessity to just watching them for fun! REASON: They're so simple to learn from and even just running the sound and glimpsing at the screen helps you learn a lot!
Eli I feel smarter just by listening to you, again great job !
Good video to help people understand the basics. One small correction; Ethernet carries it's Data in Frames, rather than packets. Packets don't come into play until you're at layer 3.
Thank you. this was very helpful to me. I will definitely be watching more videos. I am the youth pastor at my church and i have been designated the staff "tech guy". your videos are very knowledgeable and professional.. .
The loop story made my day: i immediately tested it on my 5 port switch and after 30 seconds of faster and faster blinking one of the computer said: no internet access. Magic!
"Ethernet uses something called collision avoidance collision detection in order to send packets."
Ethernet uses CSMA/CD (carrier sense multiple access withcollision detection) and 802.11 (WiFi) uses CSMA/CA (collision avoidance). Also Ethernet sends frames, not packets. Other than some subtle technical details this was a great introduction. Thanks for the video.
Thank you very much Eli the Computer guy for helping me with this tutorial.
i wish you a very long healthy life, believe it or not you are really changing lives with this information you take time out to put together. God Bless you!!!
