I am curious about why people are so hot to do away with promisc mode.
It seems to me
that in a modern switched environment, there should only very rarely be
unicast packets received
on an interface that does not want to receive them.
Could someone give a quick example of when I am wrong and promisc mode
would allow
a NIC to receive a significant number of packets not really destined for it?
Thanks,
Ben
