thanks! this approaches reassuring. why does it tolerate 100
macs? at first blush, i would think three or four would be a
bad enough sign.
I've seen several cases where a router goes bonkers and spews a bunch of
broken frames - more than four but usually less than a hundred. The
frames get dropped but the port doesn't get shut down. I have a hunch
that it's connected with bad memory in the router, a pointer going awry
somewhere, using some payload to fill an Ethernet frame header.
Usually it goes away by itself without further outaged conditions.
So this could be a reason to set the limit at 100 instead of 4...
another could be that the default in Foundry MG8 firmware is 128.
Also, AMS-IX implemented port security almost three years ago (we've
presented about it at AMS-IX Technical Meetings, RIPE meetings and
Euro-IX Forums).
