Note:
By default, after option 82 supporting is enabled on a DHCP relay, the device
processes a request packet containing option 82 with the replace policy. If other
processing policies have been configured before, after option 82 supporting is
enabled on the DHCP relay, the device does not change the configured processing
policies.
To enable option 82, you need to perform the corresponding configuration on the
DHCP server and the DHCP relay.
