DHCP Snooping
DHCP snooping ensures that DHCP clients obtain IP addresses from legitimate DHCP servers, and records the correspondence
between IP addresses and MAC addresses of DHCP clients to prevent DHCP attacks on the network.
In order to ensure the security of network communication services, the DHCP Snooping technology is introduced, and a
firewall is established between the DHCP Client and the DHCP Server to defend against various attacks against DHCP in the
network.

To identify the device accessed by the client, the user can enter his MAC address in the remote ID.
