config gratuitous_arp send duplicate_ip_detected
Used to ena
ble or disable the sending of gratuitous ARP requests while
duplicate IP addresses are detected
Purpose
config g
ratuitous_arp send duplicate_ip_detected [enable | disable]
Syntax
The co
mmand is used to enable or disable the sending of gratuitous ARP
request packets while duplicate IPs are detected. By default, the state is
enabled.
Description
Parameters
enable  Enable the sending of gratuitous ARP when a duplicate IP is
detected.
disable  Disable the sending of gratuitous ARP when a duplicate IP is
detected.
Only Administrator-level users
can issue this command.
Restrictions
Example usage:
To enable gratuitous ARP request when a duplicate IP is detected:
DES-3200-28:4#config gratuitous_arp send duplicate_ip_detected enable
Command: config gratuitous_arp send duplicate_ip_detected enable
Success.
DES-3200-28:4#
config gratuitous_arp learning
Used to ena
ble or disable the learning of ARP entries in ARP cache
based on the received gratuitous ARP packets.
Purpose
config g
ratuitous_arp learning [enable | disable]
Syntax
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.
Description
The command is used to enable or disable the learning of ARP entries 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 gratuitous ARP learning, the
system will not learn new entries but only do the update on the ARP table
based on the received gratuitous ARP packet.
By default, the state is enabled.
enabl
e – Enable the learning of ARP entries based on received
gratuitous ARP packets.
Parameters
disable  Disable the learning of ARP entries based on received
gratuitous ARP packets.
Only Administrator-level users
can issue this command.
