ARP

The Address Resolution Protocol (ARP) facility controls the manner in which ARP requests are sent. This option is only available on Ethernet load modules. The resulting responses from ARP requests are held in the ARP Table, which is used to set MAC addresses for transmitted data. ARP'ing the Device Under Test (DUT) allows tests and generated frames to be configured with a specific IP address, which at run time is associated with the MAC address of that particular DUT.

IP

The IP table within the ARP window specifies a per-port correspondence between IP addresses, MAC addresses (for Ethernet ports only), and the Default Gateway. IP addresses may be expressed as individual addresses or as a range of addresses.

All ARP requests (for Ethernet) are sent to the Default Gateway address. In most cases, the Default Gateway Address is the address of the DUT. When a gateway separates the Ixia port from the DUT, use the IP address of that gateway as the Default.
