6.3 How to Use DHCPv4 Relay on the Switch

This tutorial describes how to configure your Switch to forward DHCP client requests to a specific DHCP
server. The DHCP server can then assign a specific IP address based on the information in the DHCP
requests.

6.3.1 DHCP Relay Tutorial Introduction

In this example, you have configured your DHCP server (192.168.2.3) and want to have it assign a
specific IP address (say 172.16.1.18) to DHCP client A based on the system name, VLAN ID and port
number in the DHCP request. Client A connects to the Switch's port 2 in VLAN 102.
