5.2.6.2 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, the gateway uses ARP 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 the destination. If no entry is found for the IP address, ARP broadcasts a request
packet in a special format to all the machines on the LAN to see if one machine knows that it has that IP address associated
with it. A machine that recognizes the IP address as its own returns a reply. 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 the Configuration tab from the Web UI.
2. Select Devices.
3. Select System Profile from the options on left-hand side of the UI.
4. Expand the Network menu and select ARP.
5. 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.

Switch VLAN Interface Use the spinner control to select a VLAN for an address requiring resolution.
IP Address Define the IP address used to fetch a MAC Address.
MAC Address Displays the target MAC address that’s subject to resolution. This is the MAC used for
mapping an IP address to a MAC address that’s recognized on the network.
