dhcp snooping
HI,
If dhcp snooping is turned on and the rate limit is 10 packets per second then what counts as a packet? ACK, INFORM, REQUEST, OFFER, DISCOVER?
Is there some kind of official description for this by any chance?

I was kinda curious about that too. This document sums it up for me anyways. From what I get from it is all DHCP packets that go to the server are counted.

The way I understand it, all DHCP packets originating from behind a DHCP-SNOOPING untrusted port count towards the rate-limit. I can't find any hard evidence for this claim, though
