Can this measure 12vdc poe?

Yes, this tester can measure 12 volts on the DC connection, or the RJ45 power input.

Can i use this to simply test whether or not poe is enabled on a switch (for a particular port?)

The PoE Detector for IEEE 802.3 can quickly tell if there is power. I connected it to one end of a LAN cable, and inserted the other end into each port I needed to check. Very handy!

I have poe gen 2. we use the new cisco 9300 switch with the new cisco ap 4800 access points. tester only reads 12watts when it should be 30watts?

This nice PoE Gen2 actually displays _delivered_ power, not the _possible_ or _available_ power. Apparently your AP or PoE source gear is expected to provide up to 30W, but the Gen2 doesn't know or care. It only reports what your PoE source is _delivering_ to the various PoE gear being serviced. Confirm by math: multiple displayed Volts X Amps = Watts. In your case, it appears that your served PoE gear is only drawing 12W, from a 30W source, and you actually have another 18W maximum available for more devices. Enjoy your nice capacity margin!
