Usage guidelines
This command enables DHCP snooping to add Option 82 into 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 snooping information circuit-id and dhcp snooping information remote-id commands. If the received DHCP request packets contain Option 82, DHCP snooping handles the packets according to the strategy configured by the dhcp snooping information strategy command.
Examples
