I'm 35 studying for my ccna. You make it so much easy to understand.
Thank you Busani Mpofu
I am 46 with 16 years of on the job training. I am now going for my CCNA, and eventually CCNP Security and R&S. Thank you Keith, I have been following you for over 10 years, starting with CBT Nuggets.
Thank you Seth Raymond!
curious if you got your CCNA? @seth
Guys like you are supposed to live forever. "let's review what we have studied..." is very very important. Thanks.
Happy to do it, thanks for the feedback Kash911.
I'm studying for ccna in CBT and watching your videos here together they really solidify the knowledge and deepen my understanding.
Fantastic and thanks for being so good at teaching.
It's my pleasure
Thanks for the Advice!, Notepad has changed my life, 100% recommend 👍
Great to hear!
I'm studying the CCNP Enterprise track. Thank you for your videos, these help with CCNP also
You are welcome! Thank you James.
Helping me through my ICT foundation degree. Great videos that make learning fun and are not a boring textbook approach! Thanks Keith - PS: in the last quarter when you didn't get the results you were expecting in terminal, thats me all the time.
Great to hear! Thanks for that Nathan!
I've just finished studying my Netacad and taking a CCNA course and nothing for the last 3 months clicked with me until I watched your 4 videos in this playlist. I'm going for my exam in 2 weeks and feel so unprepared but am definitely feeling more confident after every video watch with your instruction. Thank you for being such an awesome instructor and person.. wish I had you as a mentor in my Networking journey
Glad I could help!
Thanks man, exceptional clarity
Glad it helped!
Great content as always Keith. Folks, don’t forget that there are lots of “givens” here, e.g. all links are at 1Gbps speeds. Remember in reality that STP makes decisions on *actual* link speeds, not link speed *capability*. So, if a link is 1Gbps-capable - so the ports at either end are 10/100/1000 - but the link is only running at 10Mbps (for whatever reason), STP makes cost decisions based on the 10Mbps speed, not on 1Gbps.
Thank you Steven Kelly
I'm loving the reinforcement of all these! I understand STP so well now!
Thank you Levi G.!
People talk about athletes and politicians being role models and inspirations. Keith Barker, you are my role model.
Thank you Død!
Automagically is my new favorite word. Love your vids Keith! Going to buy a CBT Nuggets subscription to get the most out of your and the two others video playlist!
Awesome! Thank you!
Your classes are sooo informative sir.. thank you soo much....
You are most welcome.
Really loved your break down of the various STP/RSTP features
Hi Keith - Learning CCNA - Your a legend - Information is brillaint
Thank you Flying Scotsman!
Keith, just wanted to say thank you for putting these spanning tree videos out there. You've really cleared up a concept that I was struggling with for a bit. Taking down links in the lab with rapid STP enabled and seeing the other links come up immediately is actually kind of fun lol. Keep this content coming!
Thank you Elijah
Thank u keith, God bless u.
Amazing guy and amazingly he defined .... love your teaching style ... stay blessed
Hi Keith,
Oddly I had the same issue with the port blocking not moving to a forward state whilst following your video on packet tracer too!
I need to thank you for your videos they’re fantastic, I want to join you for your next live stream but I’m a bit worried I may not be at a high enough level for it. I am working my way through your videos and can’t wait to join you on Saturdays / Sundays in the near future!
Thank you so much for your help and your dedication.
Thanks for sharing
great work!!!! dont stop. you make relaxing videos, that create an amazing learning environment!
Thank you Robert!
King Keith, marvelous mastery even after 2 years later I'm watching this and it helps on my job.
Keith, would you share a video covering your thoughts for intermediate level lab setup?
Thank you minuterain!
Straight and easy to understand thank you
Thank you Maloum MMM!
Great explanation/demostration Keith, thanks as always!
Glad you liked it!
Thanks again. I am doing a Boot Camp on Cisco CCNA ... I must get it done.
Best of luck!
hey...Keith...thanks for this lesson. It's amazing as always. I only have to watch your lessons once and they just sink right in to my brain.
Are you gonna do another live streams for another Cisco cert ???😀
My pleasure!
Another Great video Keith.
Thank you Cisco Cyber Tech!
Thank you!
You're Welcome!!
Another fantastic video. I'm loving your playlist.
Thank you so much!
Done subscribe. I don't know why there is a kind of joy when watching your video. Maybe you have a lot of facial expression and it really makes my day. Thanks!!
😊 thank you
I love your hype energy Keith, great instruction on the different types of stp. I've been trying to make sure I have a solid understanding because it seems like a foundational topic that can trip people up and this has helped a TON.
Also what's your spinning thing in the background called?
Thank you Mike.
Got that thing from Amazon, it is called Fortune Products Inc. The Swinging Sticks Kinetic Energy Sculpture - Desktop Toy Version
Happy studies!
I watched your video and then rewatched again after recreating it in Packet Tracer. I couldn't recreate it exactly as you taught it but it was great to see the ports change states as you described. The only issue I had was that Packet Tracer doesn't show the Type change from P2p Peer(STP) as in your example. Is there a way to see that in Packet Tracer? What is the tool you use for network simulation? Your videos are highly motivational! Thank you for putting this out there Keith.

Thanks again!
Is the base mac address separate from the port mac addresses on a switch? Or does it correspond to one of the switch ports (like port 1). So would a 24port switch actually have 25 mac addresses? Also, do you know a way in Packet Tracer to assign a base mac address? I was trying to match them up to yours so I can have the same working model. Packet Tracer seems to randomize them every time I add a new switch (using the base 2960). Thanks Keith! Awesome videos. Also your book helped me earn my CompTIA Net+ in 2015. Still have it on my shelf.
Thank you for the question Corey Timm.
Yes, the base MAC is separate. It can be seen in the output of show version.
Keith thanks for all this content - i have been watching your videos on STP and finally getting it. One ? though at 46:48 shouldn't either 1/1 or 2/2 have been in a BLK state? I thought when two switches have dual-connections then based on if cost was equal, bridge id being equal , priority being equal then port number would be tie breaker, meaning that one of the Designated ports should be blocking? Is that only with 802.1D, does 802.1W treat dual connections differently? Really appreciate your teaching style
Thank you for the question Kevin Michael Pratt. Just looked at that time spot, and it looked like 2/2 was indeed in BLK state.
Let me know if I read that wrong or if you want me to take another look.
Cheers!
@@KeithBarker Thanks for the immediate reply, was not sure if the port was not suppose to be blocking, but it appears that it was correct to be in blocking state. Appreciate your videos very much, please keep them coming!
Hello Keith. When you say ( this port or that port is blocking. What do you mean? Is that particular port down? ) Thanks. You are the best teacher.
Thank you for the question Robinson Saez.
In spanning tree, when the port is "blocking" for a specific VLAN, it means the port will nor forward user data frames, for that VLAN. The port isn't administratively down, it is just STP that is blocking.
i have a question, what if root switch goes down ??
This guy would be the last guy to get angry in the world.
Awesome video, I learned a great deal (not a network guy). I am trying to understand how Cisco's PVST operates when there are multiple VLANs configured. I understand that if I connect three layer 2 switches in a ring and the native VLAN is configured to span between all interconnects, PVST would block the port to break the loop. Let's say that there was a different VLAN that (VLAN ID 10) that was only configured on that interconnect that was blocked to break the Native VLAN. Would I still be able to send VLAN 10 traffic access that interconnect? As i understand, STP would block the entire port (not let any traffic cross) while PVST would only Block the Native VLAN traffic but still allow VLAN 10 to cross? It would be great to see an example of this. Thanks

Thanks again Mike M!
Thanks a lot
Most welcome
PVST+ looks much more like rapid stp than 802.1D it's a bit confusing because in rapid stp they use the alternate port and back like rapid?
On SW4, how did “int 3/1” become a RP over “int 2/3”?.. I can’t tell if the interface speeds are Gigabit or Fastethernet. -Thanks
Thank you Luis Cordero, if you could include a timestamp in the video, regarding your question, I would be happy to take a closer look and follow up!
Hi Keith,
I hope you are doing well. I have ccnp r&s and I am thinking to get into network security. I want learn more about firewalls. Which firewalls is best to start with cisco, palo alto or check point? Please advise.
Thank you
Thank you for the question Mo. If you are at a company that has a specific vendor's firewall, that is the one I would start with. If not, may want to take a look at Cisco's FirePower solution. I also like Palo Alto and Checkpoint very much.
Keith Barker thank you very much Keith.
but what happens when we have the same port ID in both interfaces? how stp will work?
Thank you for the question Yazid Boudjema. All the port IDs on a give switch are unique, so there will always be that tiebreaker of the lowest sending ports port ID.
1/0 will be designated ports
Thank you Sam!
"Wapid" spanning tree is without a doubt the worst mnemonic I've ever heard. lol
