3-19. DHCP Snooping
3-19-1. DHCP Snooping State
Function name:
DHCP Snooping State
Function description:
The addresses assigned to DHCP clients on unsecure ports can be carefully
controlled using the dynamic bindings registered with DHCP Snooping. 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.

the DHCP snooping function on the switch, the
default is Disabled.
