■ Configuring Interval of Sending Gratuitous ARP Packets
Follow these steps to configure gratuitous ARP packets for Layer 3 interfaces:
Step 1 configure
Enter global configuration mode.
Step 2
There are three types of Layer 3 interface that are able to send gratuitous ARP packets: routed
port, port-channel and VLAN interface.
interface { fastEthernet
port | range fastEthernet port-list | gigabitEthernet port | range
gigabitEthernet
port-list | ten-gigabitEthernet port | ten-range gigabitEthernet port-list |
port-channel
port-channel | range port-channel port-channel-list |}
no switch port
Enter interface configuration mode and change the port or port-channel to be a Layer 3
interface.
Interface vlan
vlan - id
Enter the vlan interface configuration mode.
vlan - id: Enter the interface VLAN ID.
Step 3 gratuitous-arp send-interval
interval
Specify the periodical interval at which the interface sends the gratuitous ARP packet.
interval: Specify the interval in seconds. The valid value ranges from 0 to 65535. Value 0 means
the interface does not periodically send gratuitous ARP packets.
