Configuring DHCP Filter

DHCP Filter

DHCP Filter

1.1 Overview

During the working process of DHCP, generally there is no authentication mechanism

between the DHCP server and the clients. If there are several DHCP servers on the

network, security problems and network interference will happen. DHCP Filter resolves this

problem.
With DHCP Filter configured, the switch can check whether the received DHCP packets

are legal and discard the illegal ones. In this way, DHCP Filter ensures that users get IP

addresses only from the legal DHCP server and enhances the network security.
As the following figure shows, there are both legal and illegal DHCP servers on the network.

You can configure DHCP Server1 as a legal DHCP server by providing the IP address and

port number of DHCP Server1. When receiving the DHCP respond packets, the switch will

forward the packets from the legal DHCP server.

Additionally, you can limit the forwarding rate of DHCP packets on each port.

1.2 Supported Features

The switch supports DHCPv4 Filter and DHCPv6 Filter.
