Chapter 6 Tutorials Figure 35 Tutorial: Check the Binding If DHCP Snooping Works 6.3 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. Figure 36 Tutorial: DHCP Relay Scenario DHCP Server 192.168.2.3 Port 2 PVID=102 A VLAN 102 172.16.1.18 6.3.2 Creating a VLAN Follow the steps below to configure port 2 as a member of VLAN 102. 1 Access the web configurator through the Switch's management port. 2 Go to Basic Setting > Switch Setup and set the VLAN type to 802.1Q. Click Apply to save the settings to the run-time memory. GS1920 Series User's Guide 48
