Proxy ARP Settings

The Proxy ARP (Address Resolution Protocol) feature of the Switch will allow the Switch to reply to ARP requests
destined for another device by faking its identity (IP and MAC Address) as the original ARP responder. Therefore,
the Switch can then route packets to the intended destination without configuring static routing or a default gateway.
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.

Click the Edit button to re-configure the specific entry and select the proxy ARP state of the IP interface. By default,
