I knew it would change when they started using all 8 wires. Some of the Network+ texts and CCENT texts explained the pinouts for 4 wire crossovers and they had the 568A on one end and 568B on the other. I’m just trying to make sure I have this dialed in, because I’m having to re-take the A+ for a degree program, but will then switch to Networking courses.

I’ve used your videos to prep for A+ and Network+ in the past. I’m glad you added Security+. Thank you again for your training courses.

There is a single type of crossover cable that coincidentally has the same wiring as 568A on one side and 568B on the other, but that is not the definition of a crossover cable. For example, a gigabit Ethernet crossover cable is not wired by using 568A on one side and 568B on the other.

That it just won’t work. Actually, this configuration is used all the time. It’s called a crossover cable. It would also work on devices that use MDIX.
