I'm implementing an isc dhcp server that will be utilizing option 82 tags from our switches to hand out dhcp information/addresses I'd like to deny multiple requests with the same tag (if someone decides to connect a switch to our switch to have multiple devices...) is this possible? If so can someone point me in the right direction?


I think you should have a look at PER-CLASS LIMITS ON DYNAMIC ADDRESS ALLOCATION and SPAWNING CLASSES sections in dhcpd.conf man page.
