Love this channel. Ordinarily, these topics are boring and dry. However, your animated videos brings the topics to life, and makes them enjoyable to watch. Thank you!
Like I've said before, I think, this channel deserves a lot more recognition. Even for a non-native english speaker, your videos are really really well explained. Thanks for your effort!
My homeschooled middle schoolers are going through each of your 90+ videos and writing reports on them. Thanks for the resource and breaking it down so anyone can understand.
Passed my server+ exam a week ago partially with the help of videos like these. For once I already knew most of the topic of this video which is awesome. Thanks powercert for all your videos, they're always very well explained.
Incredibly helpful and informative video, as always! I’ve referenced your videos so many times over the years and it’s great to see that you are still making them. Thank you so much for your service to the community.
The way you explain topics in such a easy to comprehend manner is second to none, you should write a book! You have helped me tremendously in my journey in the IT world, thank you 🙏🏻
This guy is the best guy when it comes to this kind of information, thanks man. very simple and straight to the point no showing off or personal entertainment.
Nice summary. You touched here on the difference between a Layer 3 switch and a router. I think a full 5-10 minute video on this topic would be helpful. Questions might include: Why would I choose one vs. the other? Advantages/disadvantages relative to the other?
There is none. Every device that is called "router" is doing layer 3 routing and forwarding. Back when I was young, the term "switch" really just meant layer 2 and especially to distinguish it from "hub" which didnˋt have a proper forwarding mechanism based on destination MACs but simply forwarded frames to every conncted device. This video muddles the differences quite a bit.
@@broodjenoodles Layer 3 is referring to the Network Layer which is very commonly the IP layer in most networks and forwarding IP packets is what has been called "routing" since the dawn of time because Layer 3 is the first layer where you actually can have multi-hop routes that require determining the actual path through the network, hence the name Network Layer. Layer 2 is point-to-point only. NATing is basically just a hack to solve the limited 32bit IP address range in IPv4. Even if a router doesn't support it, it's still a router as it handles Layer 3 traffic.
Great video, thanks for clearing this distinction up. I have heard of the two types of switches at work but never understood the final details. My only question (or critique) would be if you extended the comparison table at the end to compare the difference between a Layer 3 switch and a Router. You mentioned that Layer 3 switches can't do everything that a router does, so cliffhanger!! Plus it would make for a good review of what exactly a router does. Thanks
Love the way this is broken down and only the most useful information is presented. It's so much easier to understand the details. Thank you kind sir 🙏
As always accurate in a few minutes of video. Beautiful! I’ll tell you, you could also make it slightly longer and make them more complete but also like this is perfect
Another video that just makes so much sense!!! I'm studying for my Network + at the moment and absolutely love your videos, as they helped me with my 1101/1102 A+.
In my IT career with more than 20 years I think this is the most simplest way which explained that any one can understand the most interesting part is your graphical representation which takes me 20 years back nostalgia😊
By the way - consider making a video on port isolation too - that could be useful knowledge too. As an example clients on a network shouldn't normally be able to have intercommunication. That way you could make it harder for an intruder to penetrate workstations. It might not help protecting the servers, they have to be protected by other means. If you have port isolation between clients and have the servers on a different subnet with firewall protection of the clients so that infected servers can't reach the clients then you have an improved technical solution that could create a stronger protection against ransomware worms. I hope that I'm not too complex now though.
I have watched all of your videos in one week, thank you, I have decided to begin learning networking, because I am tired of outsourcing other people to do that in my company and then that people didnt gave me access to my routers. Do you have more complex lectures on your members channel or do you know any beginner friendly literature for more complex networking?
You should create a Network+ or CCNA RUclips courses like this, with all the detailed animation. It’s real helpful. Just an idea 😎 you can be the next Professor Messer.
Passing packets between different IP networks, monitoring and protecing inputs (think firewall), interfacing onto your ISP device (Gateway), acting as your ISP device, etc..etc...yawn...🥱
Excellent video like always. For inter-vlan routing to work does each Vlan require its own default gateway IP or is it just the L3 switch default gateway?
Static routing is supported by almost all the recent Layer 2 switchs, they are sometimes called "Layer 2 Plus" switchs (L2+). Nowadays, what's called "full layer three switch", is a switch that can do dynamic routing (For campus switchs it's mainly OSPF, ...) If you're setting up a new campus network, even the access and distribution switchs should be full layer 3 (no more layer 2 and layer 2+), ...
A nice example, however I'd consider that the example more should be to separate access point connected clients from wired clients to limit the amount of wired traffic (network broadcasts and ARP requests) over wireless. You want to keep down the amount of unnecessary traffic on wireless since the bandwidth on wireless on a large plant is limited. Of course even segmenting the wired net would make sense to cut down the amount of noise eating into the backbone performance on a large site.
Great video. One small correction: high end enterprise and service provider switches can have routing functionality comparable to a dedicated router, but generally you’re right. They’re also eye watering expensive. 🤣
Good job! May i recommend another video topic to you and if so, i think it would be great to make one talking about how to plan/design/implement a wired network from scratch in a brand new building. standards, tools, methodologies, blueprints etc. Thanks Nessim CSE
ChatGPT : Designing a wired network for a new building involves several steps and considerations: 1. **Requirements Analysis:** - Identify the specific needs of the users and applications that will be using the network. - Determine the number of devices, types of devices, and their expected data usage. 2. **Physical Layout Planning:** - Map out the building's physical structure, considering the placement of offices, workspaces, and potential network access points. - Plan for network distribution points (data closets or cabinets) strategically located for efficient cabling. 3. **Cabling Infrastructure:** - Choose appropriate cabling types (e.g., Cat6 or Cat6a) based on current and future bandwidth requirements. - Plan the cable routes, avoiding interference and ensuring proper cable management. 4. **Network Topology:** - Decide on the network topology (star, bus, ring, etc.) based on the building's layout and requirements. - Consider redundancy and scalability in the network design. 5. **Equipment Selection:** - Choose networking equipment such as switches, routers, and access points based on performance and scalability needs. - Ensure compatibility with the selected cabling infrastructure. 6. **Standards and Compliance:** - Adhere to industry standards (e.g., IEEE, TIA/EIA) for cabling and networking equipment. - Comply with local building codes and regulations related to network installations. 7. **Security Considerations:** - Implement security measures such as firewalls, intrusion detection/prevention systems, and secure access controls. - Encrypt sensitive data to protect against unauthorized access. 8. **Testing and Validation:** - Conduct thorough testing of the entire network to ensure proper functionality. - Verify data speeds, connectivity, and reliability. 9. **Documentation:** - Create comprehensive documentation, including network diagrams, equipment configurations, and cable maps. - Document IP address assignments and any unique network configurations. 10. **Maintenance and Future Expansion:** - Establish a routine maintenance plan for the network. - Plan for future expansion by leaving room for additional cabling and considering emerging technologies. **Tools:** - Network design software (e.g., Cisco Packet Tracer, GNS3). - Cable testing tools. - Network analyzers for performance monitoring. **Methodologies:** - Follow the OSI model for a layered approach to network design. - Use the Waterfall or Agile methodologies for project management, depending on the project's scale.
