47.4 DHCP Snoop Commands

Use these commands to configure or show DHCP snooping settings on the subscriber ports.
The system gets the client MAC-IP address information (in the reply from a DHCP server) and
stores it in the DHCP snooping table. The system only forwards packets from the clients
whose MAC-IP address is in the DHCP snooping table. Packets from unknown IP address(es)
are not forwarded (dropped). This feature prevents clients from assigning their own static IP
addresses.
