4.5.6 DHCP Snooping
DHCP Snooping is used to block intruder on the untrusted ports of DUT when it tries to intervene by injecting a bogus DHCP
reply packet to a legitimate conversation between the DHCP client and server.
Configure DHCP Snooping on this page. The DHCP Snooping Configuration screen in Figure 4-5-6 appears.
