does WS-C3750V2-48PS-S support CAT 6 cabling

only Cat 3, 4, or 5
see table-2 in this link:

Yes, i had checked that link Reza, but Cat 6 definition says as below which is confusing
Category 6 cable, commonly referred to as Cat 6, is a standardized cable for Gigabit Ethernet and other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards. Compared with Cat 5 and Cat 5e, Cat 6 features more stringent specifications for crosstalk and system noise. The cable standard provides performance of up to 250 MHz andis suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), 1000BASE-T/1000BASE-TX (Gigabit Ethernet) and 10GBASE-T (10-Gigabit Ethernet).

You answered your own question when you read the TIA spec's It is backwards compatible.
If you have an old device that needs cat 5 for instance read that as it needs at LEAST cat 5 peformance.
Cat 6 was introduced to allow higher bandwidth and better immunity to introduced noise.
Cat 6 is backwards compatible with cat5/5e and even cat3 for that matter.
Cat 6 (250mhz) or '6a'(500mhz) simply allows for better crosstalk and noise performance than the previous standards.
Note with cat anything you have to use components ( patch cable, panel, horizontal cable etc.) designed for that standard end to end or you won't truly see the benifits of the standard.
Find a good qualified intaller, and make them provide documentation from whatever tool they are doing the cable certification with to you before you pay them.
Maintaining twist rate, bend radius and generally doing a good job of routing and terminating is critical at cat 6/6a (If anyone is selling you 6e ask exactly what their version of 6e is as the TIA never specified a 6e standard)

As far as I know, Cat 6, for copper gig, doesn't expect an electrical difference at the port, so it should work. However, at Reza noted it might not be "officially" supported (along with Cat 5e and Cat 6a, also missing from that table).
