Command: config gratuitous_arp learning enable
Success.
DGS-3620-28PC:admin#
41-4 config gratuitous_arp send dup_ip_detected
Description
This command is used to enable or disable the sending of gratuitous ARP requests when a
duplicate IP address is detected. By default, the state is disabled. For this command, 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 out there is
using an IP address that conflicts with that of 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.
Format
config gratuitous_arp send dup_ip_detected [enable | disable]
Parameters
enable - Enable the sending of gratuitous ARP requests when a duplicate IP is detected.
disable - Disable the sending of gratuitous ARP requests when a duplicate IP is detected.
Restrictions
Only Administrators, Operators and Power-Users can issue this command.

41-5 config gratuitous_arp send ipif_status_up
Description
This command is used to enable or disable the sending of gratuitous ARP requests when the IP
interface status becomes up. This is used to automatically announce the interface's IP address to
other nodes. By default, the state is disabled. When the state is enabled and IP interface is linked
up, one gratuitous ARP packet will be broadcast.
