Description

The number of ARP entries learned on the interface fell below the threshold. (Interface name=[InterfaceName], Maximum number of ARP entries=[LimitNumber], Number of learned ARP entries =[LearnedNumber], Reason for clearing the alarm=[RecoverReason])

The number of dynamic ARP entries learned on the interface fell below the alarm clearance threshold. The alarm clearance threshold is 5% less than the alarm threshold. For example, if the alarm threshold is 80%, the alarm clearance threshold is 75%.
