DHCP Snooping Commands
DHCP snooping allows a switch to protect a network from rogue DHCP
servers or other devices which send port-related information to a DHCP
server. This information can be useful in tracking an IP address back to a
physical port. This section describes commands used to configure DHCP
snooping.
ip dhcp snooping
This command enables DHCP snooping globally. Use the no form to
