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.
DHCP Snooping: Set to disable or enable the DHCP snooping function on the
switch, the default is Disabled.
