Hey Keith, I really appreciate the time that you invest to teach us and help us with this labs. Thank you for the knowledge that you are sharing, may God bless you LOTS!! Greetings from Costa Rica!!
Did this lab over and over until it really sunk in and made sense. I took this topology and made it my own. I scaled it out to include even more vlans and DHCP IP scopes, 10.x.x.x, 172.16.x.x and a 192.168.x.x network with a /24 mask. This last time I built the network topology it worked perfectly on the first attempt. Previously I made a network similarly and it didn't work on the first try. So, I started to troubleshoot the issue. This was a test to see if I truly understand what is happening. After some troubleshooting I realized that the static IP address for my DHCP server was set to the same.as the network address for my DHCP relay address. Once I corrected that every machine grabbed the correct address. It was a great feeling and moment for me. Mr. Barker, I can't thank you enough since your teaching has taught me so much about networking and what to look for and how to troubleshoot. Next is doing custom subnetting and learning more about routing. Thanks again for all you do.
@@KeithBarker it certainly has helped as I've been working on Network discovery with SNMP, DHCP reservations and using CLI and the Cisco OS for changing IP addresses of devices to throw them on the correct subnet.
Thank you so much for putting me back on track. I started in internetworking when Cisco had AGS (I think that was the model) routers. So its really nice to have this CCNA playlist and have someone like Keith be so encouraging. Ok, so this lab as easy as it seems took me a bit to get working (well two whole days) I have learned to add CLI commands just as fast as Keith. So here are some of my curiosities: 1. After the configuration from sw1 I am not able to ping the server or any other client or server. I think I have this figured out that SW1 does not have a management IP address. Also trace IP ending up in the bucket is hard to brake on an apple laptop. 2. Spanning tree orange ball on the two links between SW1 and SW2, this is why I trashed the configs and took me nearly 2 days on this lab. I think this is ok but I would like to understand the orange balls. Anyway thank you very much all this.
wow..I thought I knew how to configure all the required Configurations.....watching this video taught me bunch of stuff I didn't know. So many new commands to learn. gonna have to watch DHCP relay thing. Thanks very much for this lab , Keith . so much to learn.😀
Keith, great video!! i have been learning Cisco on & off for the last few months and not really getting anywhere. Have subscribed to your channel i am really enjoying getting back into it. Really like your way of teaching
I completed the lab! I kept messing up the switchport mode access and switchport access commands. Kept flipping them, but it was great! Thank you Keith and everyone who helped!
I typed the Configuration commands in notepad like you did..and just paste it on packet tracer. I never knew that method before. That's my biggest takeaway from this video..and also the ip helper command. Thanks Keith.😀
Thank you Keith for taking the time to put this stuff together and for making it fun to learn, that's the real difference between your content and other contents, the humor makes it enjoyable. I created the lab and added a second Webserver and hosted a static webpage as well, felt good to see that. The sloth though.....reminds of Zootopia on Disney+.
Thank you for working on that lab, and bonus points on the hosted webserver! Hands on practice is one of the best ways to build your skills, and get better. Thank you!
You are so great, Tutorials you provide are not only exam-oriented or just useful, on the top of it, it is interesting, you gain a feeling like suddenly find out a solution for a long-standing puzzle. GREAT!!! Thank you.
This was a very challenging lab. I tried to do it on my own and wasn't able to get through it without watching the video. I place to repeat it a few additional times to ensure I understand all the concepts.
Thank you David Laufer! Taking the time to go through the hands on practice is one of the best ways to learn the technology. My hat is off to you! Way to go.
Hey Keith, I really appreciate your work on this course and i had completed this lab in less than 30 min. It was so fun and dope!! Wish you would do more labs.
I love you man ! The lab is fantastic ! I read from the text book then I come to watch the corresponding videos ! I really feel totally different and confident and have a deeper understanding after watching your videos! Thanks KEITH !
So I did this while reading the netacad book. and they tell me what it does and I understand it. but just love the way you also explain it. just love you energi :D
Hi Keith, good reinforcing of concept. I did not realise, until I di this lab, that creating the VTP domain will replicate the VLANs from the L3 SW3 to the other L2 switches. I did find the DHCP start giving out some IP address from the pre-configured severpool range but 'bouncing' the end devices brought it back correctly, thanks for the lab
I completed the lab! I just finished a CCNA course at my local college, you make it so much fun and interesting! Using your videos to get ready for my cert!
Awesome videos. As a recent convert from Meraki, your videos are welcome change from a lot of the boring, syntax only videos! Thanks! Looking forward to more!
I finish this awesome practice lab today. Thanks Keith your videos help me a lot. I wish you the best in everything you do. Best regards from San Juan Puerto Rico.
Thanks Keith (and Dan) This helped me study for my CCNA really needed to review this after missing a scenario on my Cisco practice exam that required configuring DHCP.
Awesome lab Keith. I got a better understanding of these commands and how they all fit together. Funny thing is I made all the same slip-ups as you did when I tried the lab by myself. Great fun.
Just scheduled my exam for the 19th! I read through Lammle's great 200-301 book and took an online weeklong course. Now to bust out these labs and the master playlist :)
Seriously, watching something not work as it should and then seeing how you fix it is practical knowledge and it helps more than hours of cramming. Glad you leave that stuff in.
I completed it. Good idea to type End when done configuring a step. Also, when pinging PCs, make sure you look at the IP address YOUR OWN packet tracer assigned. I was trying to ping what Keith had and the IP address assigned by DHCP were different between his and mine.
I have to be super critical with this lab in that there were huge distractions 1. VTP (and how to configure it) is NOT a part of the CCNA curriculum and not presented in the Netacad curriculum. 2. DHCP overtook the lab's focus nearly completely from a trunking exercise and made it into a dhcp configuration exercise. 3. 'comfort commands' at the beginning. I would suggest that the server and helper already be configured so that we students can spend time on actually doing what the exercise called for :TRUNKING and vlans.
I was stomped a bit because my Lan 20 was not getting DHCP. But I forgot or messed up on setting up helper. Once I performed it again it worked. I like that I screwed up, made me think about it and work a bit harder.
Hi Sir Keith! You are superb IT Teacher! Thank you very much for always sharing your knowledge to the IT Community. I just finished your packet tracer lab now. :) Hoping you can create HSRP lab (like industry real / common setup) for us please please please. Thank you in advance.
Great lab. I did most of the lab on my 3 3560 switches but i felt so embarrassed when i wasn't able to ping my PC in Vlan 10, only to find out my LAN cable was unplugged lol
Thank you very much Keith this was very helpful, also can you attach a pdf of instructions for the particular lab in the upcoming packet tracer labs and also do you have any plans for covering the network automation part of the CCNA, I appreciate it you've been a great teacher as you make complicated topics become easily understandable, I enjoy learning from you.
Thank you Muhammed! On this channel our focus is on the the technologies specific to Cisco CCNA 200-301. I appreciate your interest in more difficult and complex topologies. Thank you for watching!
I think I got it figured out after watching your next lesson on STP, those ports are in blocking mode and SW2s ports and designated as the forwarding ports
Great stuff. I am preparing for my Cisco CCNA 200-301 with your labs, videos etc. I just have one question. Why are on this topology interfaces between switches Sw1 and SW2 connected together, two times?
Way to commit to your goal Mikrotik GM❗ You can do this. Multiple connections could be used for: Etherchannel Bundling Fault Tolerance Separate primary VLANs/Networks for each connection, with a fallback to the other combinations of the above.
Amazing video. I had one quick question. What is up with the Fa0/11 and 22 connection on SW1? ip interface brief shows that they are up but the color is orange and it is slowly driving me insane.
Thank you for the question @dei_walker. At the end of the day PT is a simulator, not an emulator. The orange could be due to a trunk that is forwarding for some vlans, but blocking for others. That is one example I can think of where an UP port may have an orange indicator on live gear.
Thank you Keith for doing this. I have a question here- assuming I dont use VTP, do I need to configure vlan 777 on SW1 for all the communications to happen. Why should the trunks on SW1 need to allow vlan 777 since we anyway dont have any host communicating to the vlan 777 in L2. I'm confused. Could you pls help here?
Thank you for the question anitha soundararajan. If a trunk is expected to carry a VLAN between 2 other switches, that middle switch needs to have knowledge of that VLAN, otherwise it will drop those frames.
Hi Keith, great videos by the way. I was curious as to why on the layer 2 switches you didn't configure the trunks with dot1q encapsulation and only did that on the layer 3 switch?
Thank you for the question Bob. On the multilayer switch, it supports the older ISL as well as 802.1Q for trunking. On the layer 2 switches, they only support 802.1Q for trunking, so that is why I didn't specify the protocol for trunking on those 2 switches. Hope that helps, and happy studies.
Hey Keith, thanks for the great tutorial. Question. I have downloaded the lab and realized that on this layer 3 switch, routing vlans can only be done via the vlan interfaces and not in the sub-interfaces. Does this apply to all layer 3 switches?
Thank you for the question Randy. If the multilayer switch is doing inter VLAN routing , the only option is the SVIs, the Switched Virtual Interfaces. If we had an external traditional router, that is where we could trunk to that and then on the external router configure sub-interfaces for router on a stick (ROAS). Let me know if that helps, and thanks for watching!
@@KeithBarker Thanks so much. Yes it did answer my question. Keep up with the stellar tutorials and please be safe with your family in these trying times.👍
Taking my CCNA in 3 weeks, your labs have been super fun and informative, hoping it leads to my success. Thanks Mr. Barker!
