1) there is no Category 6e, so we have no tips on it. No Cat 6e has even been proposed
2) You can use any settings you like they will be just as valid as any other settings as there is no such standard.
3) it might be anything, but I bet it never will be, Cat 7 is already in the standards process and slowly working it's way along, so I don't see the point of a Cat 6e committee being formed.one wonders.
4) Since Cat 6e is not a standard but what ever some advertizing brouchure says it is, you could ask the vendor trying to sell it
I tried to remain child-like, all I acheived was childish.
