ARP
Profile Network Configuration
Address Resolution Protocol (ARP) is a protocol for mapping an IP address to a hardware MAC
address recognized on the network. ARP provides protocol rules for making this correlation and
providing address conversion in both directions.
When an incoming packet destined for a host arrives, ARP is used to find a physical host or MAC
address that matches the IP address. ARP looks in its ARP cache and, if it finds the address,
provides it so the packet can be converted to the right packet length and format and sent to its
destination. If no entry is found for the IP address, ARP broadcasts a request packet in a special
format on the LAN to see if a device knows it has that IP address associated with it. A device that
recognizes the IP address as its own returns a reply indicating it. ARP updates the ARP cache for
future reference and then sends the packet to the MAC address that replied.
To define an ARP supported configuration:
1. Select Configuration > Profiles > Network.
2. Expand the Network menu to display its submenu options.
3. Select ARP.
4. Select + Add Row from the lower right-hand side of the screen to populate the ARP table with
rows used to define ARP network address information.
