Usage Scenario
To enable a DHCP relay agent to insert the Option 82 Subscriber-ID into DHCP request packets on a specified interface, run the dhcp option82 subscriber-id insert enable command. The Option 82 Subscriber-ID carries Internet service provider (ISP) information, allowing the DHCP server to assign addresses and other parameters based on the ISP information if the server supports the Subscriber-ID sub-option.
