Gratuitous Arp - D-Link DWS-3160-24TC Reference Manual

DWS-3160 Series Gigabit Ethernet Unified Switch Web UI Reference Guide
The host, usually a layer 3 switch, will respond to packets destined for another device. For example, if hosts A and
B are on different physical networks, B will not receive ARP broadcast requests from A and therefore cannot
respond. Yet, if the physical network of A is connected by a router or layer 3 switch to B, the router or Layer 3
switch will see the ARP request from A.
This local proxy ARP function allows the Switch to respond to the proxy ARP, if the source IP and destination IP
are in the same interface.
