Usage Guideline The DHCP snooping function validates the DHCP packets when it arrives at the

By default, DHCP snooping will verify that the source MAC in the Ethernet

header be the same as the DHCP client hardware address to pass the validation.

Use the no ip dhcp snooping verify mac-address to disable the check for the

MAC address.

Example This example shows how to enable the verification that the source MAC address

in a DHCP packet matches the client hardware address.
