On a Cisco switch, the commands should be similar to what’s shown below:
Myswitch(config)#interface GigabitEthernet3/47
Myswitch(config-if)#ip dhcp snooping trust
If you’re having this issue and your NOT using Cisco switches, check your switch manual to see if DHCP Snooping is supported and disable it on the switch port that your OS X server is plugged in to.
