Address Resolution Protocol

ARP is an acronym for Address Resolution Protocol. It is a protocol that used to convert an IP address
into a physical address, such as an Ethernet address. ARP allows a host to communicate with other
hosts when only the Internet address of its neighbors is known. Before using IP, the host sends a
broadcast ARP request containing the Internet address of the desired destination system.
The ARP subject is covered by the following displays:
•
ARP Inspection Configuration

Port Mode Configuration

4.8.3.1 ARP Inspection Configuration
This section provides ARP Inspection related configuration.
ARP Inspection is a secure feature. Several types of attacks can be launched against a host or devices
connected to Layer 2 networks by "poisoning" the ARP caches. This feature is used to block such
attacks. Only valid ARP requests and responses can go through the switch device.
