    That little anecdote at the end about auto MDI-X saved me. I was freaking out and questioning myself why I'm able to use a straight UTP to establish comms. between two PCs. Thank you for the informative video

    I cut a 4-wire 100BASE-TX riser cable with the goal of reducing cross talk and collisions for the Nintendo Switch. I also cut a crossover gigabit riser for my fiber router's connection to its ONT. The new setup is working as well as my fq_codel setup. Games are smooth as butter. I think the wires also help load balance which cpus are used by the Nintendo and the Router+ONT.
    Thanks for your awesome wire setup.

    really great video, I love the ending!
    I was sitting here wondering if I really did mess up my network because I used just straight cables...
    Everything seems to work just fine, but I've been watching this detailed video for 6 minutes and I'm starting to question my knowledge... oh nvm auto MDI-x!
    towards the end I was also getting frustrated because it seemed obvious that it should be automatic, consumers are easily confused like me! :)

    Thank you so much dear Prof./Techncien for the explaination. Could you tell me what is the diference between using straight through and crossover when we connect two switches ? is there any diference?

    I hooked a switch to a switch and used a straight through cable, and everything worked. just came here to see if I needed to switch that over, I guess I dont need to.

    • @Zakeusa
      @Zakeusa Před 4 lety

      Cisco switches have a feature called auto-mdix that notices when the wrong cable is used
      and automatically changes its logic to make the link work.

    What should i buy for home ethernet router to Laptop and if I can use the same cable for connecting computer to computer

    • @kwallaceccie
      @kwallaceccie  Před 2 lety

      Typically, a port on a home router is pinned out like a switch port, which would use a straight-through cable. However, a PC-to-PC connection would use a crossover cable.

  • @zachattack327
    @zachattack327 Před 4 lety

    Hello I am curious on what happens on the T+ to R+ white and orange wire compared to the T- to R-. Im guessing that it’s the - voltage on orange and + voltage on orange and white. can you please tell me how data transfer is different between the two due to the polarity difference regardless that they both have R on one end and T on another?Thank you

    @phillychannel394 Před 2 lety

    My inexperienced co-workers used crossover cable in our network ranging from 4th, 3rd to 2nd floor in many different rooms/offices which were interconnect through several switches and routers and claim the cabling method they used are the correct method. I tried to tell them it isn't the proper method but they won't listen. Ridiculous.

    Does crossovering makes sense to gigabit connections?

  • @granvillebarraclough8846

    Am no expert but the T568B to T568A crossover (green and orange swapped over) doesn't seem to work for the 8 pin data crossover.

    Which cable will be use to connect Layer 2 switch to Layer 3 switch ? Answer ? 🤔🤔

    • @kwallaceccie
      @kwallaceccie  Před rokem

      Assuming MDIX is enabled, a port speed not exceeding 10Gbps, and a distance not exceeding 37m, a straight through Cat 6 Ethernet cable should do the trick. (or a crossover cable if MDIX is not enabled)

    Why all those guys who show how to make a crossover cable do not flip the pins 4-5 and 7-8??

  • @kongol5036
    @kongol5036 Před 3 lety

    No wonder when I had to copy an imac to another imac it wanted me to just use a patch cable. Pretty cool, didn't know about the auto mdi-x

    What if we switch blue with green, so that we now have pairs of orange, pairs of green, pairs of blue, and pairs of brown?
