Usage Guidelines

After dynamic ARP inspection (DAI) is enabled in the interface view, you can run this command to check statistics about discarded ARP packets matching no binding entry on the interface. If the alarm function for ARP packets discarded by DAI is enabled, you can also check statistics about discarded ARP packets matching no binding entry on the interface after the latest alarm is generated.

If DAI is enabled only in the VLAN view, this command cannot be run to display statistics about discarded ARP packets matching no binding entry on the interfaces in the VLAN.

Example
