Used to enable or disable the sending of gratuitous ARP requests while
duplicate IP addresses are detected
config gratuitous_arp send dup_ip_detected [enable | disable]
The command is used to enable or disable the sending of gratuitous ARP
request packets while duplicate IPs are detected. By default, the state is
enabled.
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, Operator level or Power User level users can
issue this command.
Used to enable or disable the 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 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.
enable – Enable the learning of ARP entries based on received
gratuitous ARP packets.
disable − Disable the learning of ARP entries based on received
gratuitous ARP packets.
Only Administrator level, Operator level or Power User level users can
issue this command.
