Configure DHCP Snooping
DHCP snooping is a useful feature that provides security by filtering untrusted DHCP
messages and by building and maintaining a DHCP snooping binding table. An untrusted
message is a message that is received from outside the network or firewall and that can
cause traffic attacks within your network. The DHCP snooping binding table contains the
MAC address, IP address, lease time, binding type, VLAN number, and interface information
that corresponds to the local untrusted interfaces of a switch. An untrusted interface is an
interface that is configured to receive messages from outside the network or firewall. A
trusted interface is an interface that is configured to receive only messages from within the
network.
