If you’re the network operator you can mitm network traffic if curse. If you aren’t how are you running a dhcp server when the switch will block the packets?

- grahamburger 6y agoSwitches don't typically block DHCP packets. You can literally just spin up your own DHCP server and plug it in to a switch port - if your fake server responds to a DHCP request faster than the legit DHCP server the client will get your lease instead of the right one. It's this way by design - it's not at all uncommon for the DHCP server to not run on the router itself, but on some other device elsewhere in the network, or even outside the layer 2 network using a DHCP Relay.
