Setting up DHCP Relay Option 82

In this application example, we will show you how to configure the IES-5000 to assign a specific IP address in the client IP pool to a computer based on its DSL port, VLAN ID and the option 82 string.

For this example, assume that the computer is connected to DSL port 25 with an Option82 string of “5000” in VLAN 1. We will use the IP Commander DHCP server (192.168.1.99) to assign this computer an IP address in the client IP pool of 192.168.1.201~192.168.1.203.

1. IES-5000 settings

On the IES-5000, enable DHCP relay and specify the IP address of the DHCP server (192.168.1.99). Then enable Option82 and enter “5000” as the string.

CI command:

TGE1> ip dhcprelay enable

TGE1> ip dhcprelay relay enable

TGE1> ip dhcprelay server 1 192.168.1.99

TGE1> ip dhcprelay relayinfo add 5000
