Suppose there is a DHCP server placed on a network without permission. When there

leading the user to get a wrong IP address. In this case, the user will be unable to
access the network. Such a DHCP server is called DHCP pseudo-server.
After a DHCP pseudo-server detection-enabled, switch will record the information of
the DHCP servers such as their IP addresses so that the administrator can discover the
DHCP pseudo-servers.
