The number of the discarded ARP packets that did not match the binding table exceeded the threshold on the interface. (IfIndex=[IfIndex], VlanIndex=[VlanIndex], VsiIndex=[VsiIndex], Interface=[IfName], VlanID=[VlanID], DiscardedNumber=[DropNum])
The number of discarded invalid ARP packets exceeded the configured threshold.

1. Check whether the device is attacked and determine whether to adjust the alarm threshold for the number of the discarded invalid ARP packets.
2. Collect log information and configuration information, and then contact technical support personnel.
