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 25
th
DSL port and the option 82 string is a string “5000”. 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
“5000”.
1. IES-5000 settings
Enable the DHCP relay and Option 82 function including the IP address of DHCP
server. The IP address is 192.168.1.99 in our case. Also, enter “5000” as the Option 82
string.
CI command:
TGE1> ip dhcprelay enable
TGE1> ip dhcprelay relay enable
TGE1> ip dhcprelay server 1 192.168.1.99
