How to Use DHCP 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.
