Hi,
we've are using with success DHCP Snooping with DHCP relay configured...but I was wondering if the DHCP Snooping feature is working also on a L2 network (composed by different switches) where the DHCP Server is on the same VLAN as the client?
I know that Server have to be in a dedicated VLAN but VLAN segmentation DHCP Server - client is planned in a second step...
Thanks for your suggestions!

Hi Omar,
The DHCP server can be on the same VLAN as the clients, no problem with this.
You need to configure the DHCP server's port as trusted with the following commands:
conf t
ip dhcp snooping
ip dhcp snooping vlan x
interface fastethernet x/y
ip dhcp snooping trust
fastethernet x/y will be the port where the DHCP server should be located.
