Steve,
The GIGAswitches support filtering based on several parameters (e.g.
MAC source/destination address, switch ports, etc.). We currently employ
filtering based on ports (vs. MAC addresses) to logically partition the
GIGAswitches. I think this is prudent since the MAC addresses will change
if (er, when :-) )we ever have to swap out failed equipment.
