Usage guidelines
This command enables the DHCP relay agent to add Option 82 to DHCP requests that do not contain Option 82 before forwarding the requests to the DHCP server. The content of Option 82 is determined by the dhcp relay information circuit-id and dhcp relay information remote-id commands. If the DHCP requests contain Option 82, the relay agent handles the requests according to the strategy configured with the dhcp relay information strategy command.
If this feature is disabled, the relay agent forwards requests that contain or do not contain Option 82 to the DHCP server.
Examples
