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.
