4.12.8 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 4-12-8 appears.
Figure 4-12-8 DHCP Snooping Configuration screen page screenshot
The page includes the following fields:
Object Description
Snooping Mode
Indicates the DHCP snooping mode operation. Possible modes are:
Enabled: Enable DHCP snooping mode operation. When enable DHCP
snooping mode operation, the request DHCP messages will be forwarded to
trusted ports and only allowed reply packets from trusted ports.
