Thanks for all those explanation, We have exactly the same environment as you described and I want to enable DHCP snooping, but I don’t really understand why I have to enable dhcp snooping on two core switches (ITKEBB01 and ITKEBB02) and also on two SW server farm, my understanding from Cisco docs is that we have to enable dhcp snooping on the Access switches (ITKES01) and trust uplinks to core and it should works.?
And also how about the binding table do you know how its built? I know that is dynamically but if client has already ip address before enabling dhcp snooping and try to renew address after dhcp snooping enabled, is the binding table is filled out with all his information’s?

How layer 2 switchs filter dhcp messages that work at layer 3
