Chapter 31 DHCP

GS2200-24 User’s Guide

computer on your network, it contacts the DHCP server for the necessary IP 
information, and then relays the assigned information back to the computer. 

31.3.2  DHCP Configuration Options

The DHCP configuration on the Switch is divided into 

Global

 and 

VLAN

 screens. 

The screen you should use for configuration depends on the DHCP services you 
want to offer the DHCP clients on your network. Choose the configuration screen 
based on the following criteria:

•

Global

: The Switch forwards all DHCP requests to the same DHCP server.

•

VLAN

: The Switch is configured on a VLAN by VLAN basis. The Switch can be 

configured to relay DHCP requests to different DHCP servers for clients in 

different VLAN.

31.3.3  DHCP Relay 

Configure DHCP relay on the Switch if the DHCP clients and the DHCP server are 
not in the same broadcast domain. During the initial IP address leasing, the 
Switch helps to relay network information (such as the IP address and subnet 
mask) between a DHCP client and a DHCP server. Once the DHCP client obtains an 
IP address and can connect to the network, network information renewal is done 
between the DHCP client and the DHCP server without the help of the Switch.

The Switch can be configured as a global DHCP relay. This means that the Switch 
forwards all DHCP requests from all domains to the same DHCP server. You can 
also configure the Switch to relay DHCP information based on the VLAN 
membership of the DHCP clients.

31.3.4  DHCP Relay Agent Information 

The Switch can add information about the source of client DHCP requests that it 
relays to a DHCP server by adding 

Relay Agent Information

. This helps provide 

authentication about the source of the requests. The DHCP server can then 
provide an IP address based on this information. Please refer to RFC 3046 for 
more details. 

The DHCP 

Relay Agent Information

 feature adds an Agent Information field to 

the 

Option 82

 field. The 

Option 82

 field is in the DHCP headers of client DHCP 

request frames that the Switch relays to a DHCP server.

Relay Agent Information

 can include the 

System Name

 of the Switch if you 

select this option. You can change the 

System Name

 in 

Basic Settings

 > 

General Setup

.
