Can I use DHCP snooping and IOS DHCP server on the same switch stack

Hello,

I am shortly going to be deploying a Cisco CallManager solution for a customer whose network comprises stacks of Catalyst 3850 switches.

There is no separate core/server farm switch so the CallManager servers, voice gateways and IP phones will all plug into the same stack and be in the same VLAN (not my choice!).

For security we want to enable DHCP snooping and were planning on using the IOS DHCP server on the Catalyst switch stack.

Will this work? - when I enable DHCP snooping in networks with separate access layer switches I set the uplinks to the core as trusted links.

I am not sure whether DHCP snooping will work in this case. Do I need to set the VLAN interface on the switch as trusted, is this even possible?

Unfortunately I do not have access to a layer 3 switch to test this at the moment.

Thanks
