DHCP Snooping is a feature in Cisco routers and switches that provides security by filtering untrusted DHCP messages and by building and maintaining a DHCP snooping binding database, also known as the DHCP snooping binding table. This feature allows the switch to verify the DHCP messages it receives before forwarding them to the clients. It also helps protect against rogue DHCP servers attempting to offer IP addresses to clients on the network.
