Parameter Description

Send On IP Interface

Status Up

The command is used to enable/disable sending of gratuitous ARP request packet while

the IPIF interface become up. This is used to automatically announce the interface’s IP

address to other nodes. By default, the state is Enabled, and only one gratuitous ARP

packet will be broadcast.

Send On Duplicate IP

Detected

The command is used to enable/disable the sending of gratuitous ARP request packet

while a duplicate IP is detected. By default, the state is Enabled. For this command, the

duplicate IP detected means that the system received an ARP request packet that is

sent by an IP address that match the system’s own IP address. In this case, the system

knows that somebody out there uses an IP address that is conflict with the system. In

order to reclaim the correct host of this IP address, the system can send out the

gratuitous ARP request packets for this duplicate IP address.
