Usage guidelines
This command enables DHCP snooping to add Option 82 into DHCP request packets forwarded 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 with the dhcp snooping
information strategy command.
