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.

number in the DHCP request. Client A connects to the Switch's port 2 in VLAN 102.
