Configuration Procedure - HP 830 Series Configuration Manual

You can enable periodic sending of gratuitous ARP packets on a maximum of 1024 interfaces.
•
• Periodic sending of gratuitous ARP packets 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 the sending interval set
•
by the user if this function is enabled on multiple interfaces, if each interface is configured with
multiple secondary IP addresses, or if a small sending interval is configured when the previous two
conditions exist.
