Hi,
When you're saying there is a MAC address limit, are your referring to the
ARP table size ?
I've did a small test using script [1] generating a jail/vnet with 2100
epairs interfaces.
And from the standard host stack, pinging all those 2100 "remote" IP
adresses: The ARP table seems able to store all of them:
# arp -na | wc -l
2109
So, how are you checking the limit of the 500 MAC ?

Olivier
