Option 82 is used by the relay agent to insert additional information into the client’s DHCP request. The Relay
Agent Information option is inserted by the DHCP relay agent when forwarding client-originated DHCP packets
to a DHCP server. Servers can recognize the Relay Agent Information option and use the information to
implement IP addresses to Clients.
When Option 82 is enabled on the switch, a subscriber device is identified by the switch port through which it
connects to the network (in addition to its MAC address). Multiple hosts on the subscriber LAN can be connected
to the same port on the access switch and are uniquely identified.
