It really does not matter which type of cable you use, you can turn on MDIX with straight through cables, the ports auto sense the pins used and change the port characteristics to ensure communication happens.

command;

mdix auto

Both answers are right.

If your switch supports Auto-Mdix, you can use either. If it doesn't you MUST use a cross over.

3560s and 3750s support MDIX, at least you have some options now.

No I am telling you (jjmartineziii) 3560s and 3750s do support MDIX since in your post you state "If your switch supports Auto-Mdix, you can use either."   obviously you do not know that they support MDIX.

yeah, and I am telling you that i didn't see s/he posted the switch types, if I saw it was a 3560/3750 i wouldn't have said "If your switch" :)
