 I've had same problem as you, but not with 7600's (which we mostly
use as routers with L3 ports only).  But with smaller cats, which
do support broadcast suppression with %, bps and pps quite spiffy.
 Unfortunately 3560/3750 do not support CoPP at all, which makes
the choise easy :)

 Please summarise to list what you find about protecting the box
from ARP. You may want to investigate and tune 'show mls rate-limit'.
