Figure 2 - 44 Gratuitous ARP Settings window
Description
This is used to enable/disable the sending of gratuitous ARP request packets while an IPIF
interface comes up. This is used to automatically announce the interface's IP address to other
nodes. By default, the state is Disabled, and only one ARP packet will be broadcast.
This is used to enable/disable the sending of gratuitous ARP request packets while a duplicate
IP is detected. By default, the state is Disabled. Duplicate IP detected means that the system
received an ARP request packet that is sent by an IP address that matches the system's own
IP address.
This is used to enable/disable updating ARP cache based on the received gratuitous ARP
packet. If a switch receives a gratuitous ARP packet, it should add or update the ARP entry.
This is Disabled by default.

packets. By default, the interval is 0.
