1- enable DHCP snooping:

ip dhcp snooping

2-appply it for example vlans you need secured

ip dhcp snooping vlan 10

3-excelude it on port where you receive DHCP offers from

ip dhcp snooping trust

4-Create a location to TFTP database to in case your box reloadsso you can fetch previous bindings.

ip dhcp snooping database tftp://172.16.1.1/DHCP/RTR1.dhcp
