5.3 DHCP Snooping
With DHCP snooping, the system obtains a client's MAC-IP address information (in the reply
messages from a DHCP server) and stores it in the DHCP snooping table. Frames with known
source IP addresses are allowed to go through the subscriber ports. Frames from unknown IP
addresses are dropped. This feature prevents subscribers from assigning their own static IP
addresses that may conflict with a DHCP-assigned IP address.
