Crossover cables are easy. I make my own straight-through and crossovers
when needed.

Regardless, the others were right: you *did* need a crossover *until*
you put an auto-sensing switch into the mix. I have one of these on my
home network (SMCGS8 unmanaged) and have sense not made up any custom
cables.

As others have stated though, I do have both cross-over and straight
patch cables on-hand JIC.

Anyway, if you make your own, when the RJ-45 connectors are held side-
by-side clips down facing same direction:

straight = colors occur in same sequence in both
cross-over = colors occur in "mirror" sequence.

For GB E'net, this is more important as two pairs are used. For 10Mb,
only one pair is used, so the simple reverse TX/RX works.

Hmmm... I'm assuming USOC 568A wiring? Can't remember. Anyway, the pin
assignments are the same. Only the color sequence is different.
