Hi guys,
Is it possible to spoof the source mac address of an outgoing frame?
I ask because when dhcp snooping is enabled on a 3550, it checks
to see if the source mac address of the frame is the same as the mac address
inside the dhcp packet.
If the 2 mac addresses are different, the 3550 will drop the packet.
Besides spoofing the source mac address, are there any possible reasons
the source mac address would be different from the mac address contained
inside the packet?
TIA, Tim
