Functional Notes
In general, the principle of proxy ARP allows a router to insert its IP address in the source IP address field
of a packet (if the packet is from a host on one of its subnetworks). This allows hosts to reach devices on
other subnetworks without implementing routing or specifying a default gateway.
If proxy ARP is enabled, AOS will respond to all ARP requests with its specified medium access control
(MAC) address and forward packets accordingly.
Enabling proxy ARP on an interface may introduce unnecessary ARP traffic on the network.

(config)#interface ethernet 0/1
