I have configured DHCP snooping with option 82. That is working OK. I then went to enable IP Source guard to help against MAC Spoofing. I enable port security and ip verify source. I connected a client to the port and the address when into the snooping database as it should. I then spoofed my MAC address on the same port with the same client and it adds another entry and ip address into the DHCP Snooping Binding database and give my client an IP address. So, it looks like my ip verify source is not working? Any suggestions?
I have this problem too.
