4.2.9 DHCP Relay 

Configure DHCP Relay on this Page. 

DHCP Relay

 is used to forward and to transfer DHCP messages between the clients and 

the server when they are not on the same subnet domain.   

The 

DHCP option 82 

enables a DHCP relay agent to insert specific information into a DHCP request packets when forwarding 

client DHCP packets to a DHCP server and remove the specific information from a DHCP reply packets when forwarding server 

DHCP packets to a DHCP client. The DHCP server can use this information to implement IP address or other assignment 

policies. Specifically the option works by setting two sub-options:   

 

Circuit ID (option 1)   

 

Remote ID (option2).   

The 

Circuit ID

 sub-option is supposed to include information specific to which circuit the request came in on.   

The 

Remote ID

 sub-option was designed to carry information relating to the remote host end of the circuit. 

The definition of Circuit ID in the switch is 4 bytes in length and the format is "vlan_id" "module_id" "port_no". The parameter of 

"vlan_id" is the first two bytes representing the VLAN ID. The parameter of "module_id" is the third byte for the module ID (in 

standalone switch it always equals 0; in stackable switch it means switch ID). The parameter of "port_no" is the fourth byte and it 

means the port number.   

The Remote ID is 6 bytes in length, and the value equals the DHCP relay agent’s MAC address. The DHCP Relay Configuration 

screen in 

Figure 4-2-12

 appears.

Object 

Description 

 

Relay Mode 

Indicates the DHCP relay mode operation. Possible modes are: 

 

Enabled

: Enable DHCP relay mode operation. When enabling DHCP relay 

mode operation, the agent forwards and transfers DHCP messages between 

the clients and the server when they are not on the same subnet domain. 

And the DHCP broadcast message won't flood for security considered.   

 

Disabled

: Disable DHCP relay mode operation. 

 

Relay Server 

Indicates the DHCP relay server IP address. A DHCP relay agent is used to 

forward and transfer DHCP messages between the clients and the server when
