Solution
To configure DHCP snooping on a Cisco switch, you need to enable DHCP snooping globally on the switch and in all VLANs that require DHCP spoofing protection. This is a mandatory step in the configuration process. DHCP snooping is a security feature that validates DHCP messages received from untrusted sources and filters out invalid messages. By enabling DHCP snooping, you can prevent DHCP spoofing attacks where an attacker tries to supply false DHCP information to clients.
