I just tried it and it logged a single MAC move from one port to another
port.

I've never seen that message on a cat6000 until after doing a 'set
movenotif ena' on the switch.  I've seen that type of msg on a cat5000 and
cat2900 without doing anything special, but not a cat6000.  Kind of a shame
really - knowing the switch is seeing the same MAC on different ports can
be very helpful troubleshooting info.
