Gratuitous ARP commands arp send-gratuitous-arp Use arp send-gratuitous-arp to enable periodic sending of gratuitous ARP packets and set the sending interval on an interface. Use undo arp send-gratuitous-arp to disable the interface from periodically sending gratuitous ARP packets. Syntax arp send-gratuitous-arp [ interval milliseconds ] undo arp send-gratuitous-arp Default Periodic sending of gratuitous ARP is disabled. Views VLAN interface view Predefined user roles network-admin Parameters interval milliseconds: Sets the interval at which gratuitous ARP packets are sent, in the range of 200 to 200000 milliseconds. The default value is 2000 milliseconds. Usage guidelines This function takes effect only when the enabled interface is up and an IP address has been assigned to the interface. This function can send gratuitous ARP requests only for a VRRP virtual IP address, or the sending interface's primary IP address or manually configured secondary IP address. The primary IP address can be configured manually or automatically, whereas the secondary IP address must be configured manually. If you change the interval for sending gratuitous ARP packets, the configuration takes effect at the next sending interval. The frequency of sending gratuitous ARP packets might be much lower than 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. Examples # Enable VLAN-interface 2 to send gratuitous ARP packets every 300 milliseconds. system-view [Sysname] interface vlan-interface 2 [Sysname-Vlan-interface2] arp send-gratuitous-arp interval 300 11
