config gratuitous_arp send dup_ip_detected
Purpose
Used to enable/disable the sending of gratuitous ARP requests while
a duplicate IP address is being detected.
Syntax
config gratuitous_arp send duplicate_ip_detected
[enable|disable]
Description
The command is used to enable/disable sending of gratuitous ARP
request packets while a duplicate IP is being detected. By default,
the state is disabled. For this command, the 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. In this
case, the system knows that somebody is using an IP address that
is in conflict with the system. In order to reclaim the correct host of
this IP address, the system can send out the gratuitous ARP request
packet for this duplicate IP address.
