Figure 4-3-23: DHCP Cheating Attack Implementation Procedure
DHCP Filtering feature allows only the trusted ports to forward DHCP packets and thereby ensures that users get proper IP
addresses. DHCP Filtering is to monitor the process of hosts obtaining the IP addresses from DHCP servers, and record the IP
address, MAC address, VLAN and the connected Port number of the Host for automatic binding. DHCP Filtering feature
prevents the network from the DHCP Server Cheating Attack by discarding the DHCP packets on the distrusted port, so as to
enhance the network security. The screen in Figure 4-3-24 appears.
