resolution. ES4626/ES4650 supports both dynamic ARP and static configuration.
Furthermore, ES4626/ES4650 supports the configuration of proxy ARP for some
applications. For instance, when an ARP request is received on the port, requesting an IP
address in the same IP segment of the port but not the same physical network, if the port
enabled proxy ARP, the port would reply to the ARP its own MAC address and forward the
actual packets received. Enabling proxy ARP allows machines physically separated but of
the same IP segment ignores the physical separation and communicate via proxy ARP
interface as if in the same physical network.
