Address Resolution Protocol (ARP) is a protocol for mapping an IP address to a hardware MAC
address. ARP provides protocol rules for making this correlation and providing address conversion
in both directions. This ARP assignment can be overridden as needed, but removes the device
configuration from the managed profile that may be shared with other similar device models.
When an incoming packet destined for a host arrives at the access point, the access point’s
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 it has that IP address associated with it. A machine that recognizes the IP address
as its own returns a reply indicating as such. 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:
Select Devices from the Configuration tab.
Select Device Overrides from the Device menu to expand it into sub menu options.
Select a target device from the device browser in the lower, left-hand, side of the UI.
Select Network to expand its sub menu options.
Select ARP.
NOTE
A blue override icon (to the left of a parameter) defines the parameter as having an override applied.
To remove an override, go to the Basic Configuration screen’s Device Overrides field and select Clear
Overrides. This will remove all overrides from the device.
