Thanks. We'll let you know when a new response is added.

Just from a fast Google of your question, Here is a fairly solid step by step guide on what you need to do to set up DHCP Snooping.

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SXF/native/configuration/guide/snoodhcp.html#wp1074087

This is for Catalyst 6500 series Switches mind you, but a fast search of Cisco’s sites for your specific router/switch + dhcp snooping should avail you of the exact answer you are seeking.

Hope this helps.
