After the DAI or IPSG function is enabled on an interface, why can the interface forward packets that do not match a bound list

Run the dhcp snooping trusted command on the AR router to check whether the DHCP snooping function is configured on the interface. If yes, all packets under this interface are considered valid and therefore can be forwarded, in spite of the fact that the DAI or IPSG function has been enabled on the interface.
