2.1.4 Configuring Proxy ARP

Proxy ARP is used in the situation that two devices are in the same network segment but
connected to different Layer 3 interfaces.
Choose the menu L3 FEATURES> ARP > Proxy ARP > Proxy ARP to load the following
page.
With this option enabled, the interface will send gratuitous ARP request packets
when its status becomes up. This is used to announce the interface's IP address to
the other hosts. It is enabled by default.
With this option enabled, the interface will send gratuitous ARP request packets
when a gratuitous ARP request packet is received for which the IP address is the
same as the interface's. In this case, the switch knows that another host is using
the same IP address as its own. To claim the IP address for the correct owner, the
interface sends gratuitous ARP packets. It is disabled by default.
Normally, the switch only updates the MAC address table by learning from the ARP
reply packet or normal ARP request packet. With this option enabled, the switch will
also update the MAC address table by learning from the received gratuitous ARP
packets. It is disabled by default.
Displays the Interface ID of the Layer 3 interface.
Enter the interval of sending gratuitous ARP request packets for the interface.
A value of 0 means the interface will not send gratuitous ARP request packets
periodically.
