5.2.3 Enable/Disable Pseudo-DHCP Server Detection
On a network, pseudo-DHCP server refers to an unauthorized DHCP server. Such a
server can communicate with a client requesting for IP address and allocate an
incorrect IP address to the client, thus preventing it from accessing the network.
With the function of pseudo-DHCP server detection enabled, the switch can record
DHCP server information such as IP address, thus allowing administrators discover
and deal with pseudo-DHCP servers.
Perform the following configuration in system view.
