E ES4710BD 10 Slots L2/L3/L4 Chassis Switch
ES4710BD 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 has enabled proxy ARP, the port would reply to the ARP
with 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.
