Sending Interface
Select one or more interfaces on which gratuitous ARP packets are sent out periodically,
and set the interval at which gratuitous ARP packets are sent.
To enable an interface to send out gratuitous ARP packets periodically, select the
interface from the Standby Interface list and click <<. To disable an interface from
periodic sending of gratuitous ARP packets, select the interface from the Sending
Interface list and click >>.
IMPORTANT:
• You can enable periodic sending of gratuitous ARP packets on a maximum of 1024
interfaces.
• This feature takes effect only when the link of the enabled interface goes up and an
IP address has been assigned to the interface.
• If you change the interval for sending gratuitous ARP packets, the configuration is
effective at the next sending interval.
• The frequency of sending gratuitous ARP packets might be much lower than is
expected if this function is enabled on multiple interfaces, or each interface is
configured with multiple secondary IP addresses, or a small sending interval is
configured in the preceding cases.
• Do not configure this feature on an interface belonging to a VRRP group.
Configuring ARP automatic scanning
IMPORTANT:
Do not perform other operations during an ARP automatic scan.
From the navigation tree, select Advanced > ARP Anti-Attack > Scan.
