How to set up DHCP Relay Option 82 Environment
Here, we will set up an environment to allow a PC get DHCP IP address in specific IP pool according to its DSL port, VLAN ID and the option 82 string. In this case, the PC is behind 25th DSL port and the option 82 string is a string “1248”. We use the IP Commander as DHCP server. Its IP is 192.168.1.99 and the IP pool is between 192.168.1.201 and 192.168.1.203 for VID=1, DSL port=25 and the option 82 string is “1248”.
