Arp Configuration Task List; Commands For Arp Configuration - Edge-Core ES4626 User Manual

MAC address. ES4626/ES4650 switch supports both dynamic ARP and static ARP
configuration. Furthermore, ES4626/ES4650 switch 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.
