Parameters

Example usage:
To enable gratuitous ARP request when a duplicate IP is detected:
DES-3028P:4#config gratuitous_arp duplicate_ip_detected enable
Command: config gratuitous_arp duplicate_ip_detected enable
Success.
DES-3028P:4#
config gratuitous_arp learning

Example usage:
To enable learning of ARP entries based on the received gratuitous ARP packets:
DES-3028P:4# config gratuitous_arp learning enable
Command: config gratuitous_arp learning enable
Success.
DES-3028P:4#
enabled. For this command, the duplicate IP detected means that the
system has received an ARP request packet that was sent by an IP
address that matched the system's own IP address. In this case, the
system knows that somebody out there uses an IP address that is
conflicting 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.
enable  Enable sending of gratuitous ARP when duplicate IP is
detected.
disable  Disable sending of gratuitous ARP when duplicate IP is
detected.
Only Administrator-level users can issue this command.
Used to enable/disable learning of ARP entries in ARP cache based on
the received gratuitous ARP packets.
config gratuitous_arp learning [enable|disable]
Normally, the system will only learn the ARP reply packet or a normal
ARP request packet that asks for the MAC address that corresponds to
the system's IP address.
The command is used to enable/disable learning of ARP entry in ARP
cache based on the received gratuitous ARP packet. The gratuitous ARP
packet is sent by a source IP address that is identical to the IP that the
packet is queries for. Note that, with the gratuitous ARP learning, the
system will not learn new entry but only do the update on the ARP table
based on the received gratuitous ARP packet.
By default, the state is Enabled.
enable – Enable learning of ARP entries based on the received
gratuitous ARP packet.
disable  Disable learning of ARP entry based on the received gratuitous
ARP packet.
Only Administrator-level users can issue this command.
