2.4 DHCP Security Configuration

DHCP security configuration is needed to ensure the security of DHCP service.
2.4.1 Prerequisites
Before configuring DHCP security, you should first complete the DHCP server
configuration (either global address pool-based or interface address pool-based
DHCP server configuration).

2.4.2 Configuring Private DHCP Server Detecting

A private DHCP server on a network also answers IP address request packets and
assigns IP addresses to DHCP clients. However, the IP addresses they assigned may
conflict with those of other hosts. As a result, users cannot normally access networks.
This kind of DHCP servers are known as private DHCP servers.
With the private DHCP server detecting function enabled, when a DHCP client sends
the DHCP-REQUEST packet, the DHCP server tracks the information (such as the IP
addresses and interfaces) of DHCP servers to enable the administrator to detect
private DHCP servers in time and take proper measures.
