DHCP Snooping query

Unanswered Question
Sep 22nd, 2007

If you configure DHCP snooping on a VLAN that doesn't have a DHCP server directly attached i.e. using ip-helper command, where is the trusted port? I know it is the port connected to the router in a standard environment, but if I am using a Layer 3 switch, do I need to trust the SVI interface, or the physical interface that the DHCP server is connected to, even if it on a different VLAN?
