Crossover: Pinouts of 10/100/1000BASE-T crossing cable is shown in Figure 10-8.

The 10/100/1000BASE-T crossing cable is different from a 100BASE-TX crossing
cable. The pinout of a 100BASE-TX crossing cable in one end is based on the 568B
standard, and other is based on the 568A standard. By the way, the pinout of a
10/100/1000BASE-T crossing cable in one end is based on the 568B standard, and
other isn't based on the 568A standard.
