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
# Enable DHCP snooping to support Option 82.
