4.1.4.8 ARP Inspection
ARP (Address Resolution Protocol) is the protocol to parse the IP address into Ethernet MAC
address (the physical address).
In LAN, when the host or other network device needs to forward data to another host or other
network device, the IP address of the target host or other network device should be known.
Besides IP address, the forwarding station needs to know the physical address of the accepting
station, because the IP data packet should be sent through the physical network as packaged
frame. A mapping from the IP address to the physical address is needed. ARP is the protocol to
realize the function.
Enable ARP Inspection
