Switches don't normally do this type of stuff. Firewall required.

What make/model switch?

Where is the host located and where is the DHCP server located?
Cisco provides a feature on several of their Catalyst switches called "DHCP Snooping" that does what you are looking for.  The feature is described in "Securing the Wiring Closet with Cisco Catalyst Switches":

Configuration example is contained in their "Catalyst 6500 Series Software Configuration Guide" - don't be put off that its in the 6500 guide, its the best example describing the feature for many of the Catalyst line.
