Can't you hard code MAC addresses into the PM? I am relatively certain
that the cisco can do that, although I haven't had a need to do so. You
couldn't filter based on MAC address, but you could assign a MAC address to
a specific IP address and then filter based on IP address. For extra IP's
on the subnet, simply assign a nonexistent MAC address, and they would be
unusable.
This is not going to help for hosts on the same subnet, but that problem
could be solved with a switch.
