In network deployments where the switch detects random spurious link flaps, network performance is affected due to the frequent unwanted re-convergence of topology for protocols like spanning tree, OSPF, and link aggregation.
The link debounce feature tries to solve this problem by delaying the link-down event notification to applications by waiting for a configurable duration of time known as the debounce time. During this time, the link may cycle through down-and-up states several times before it finally settles down. If the link goes down (and stays down), applications are notified after the debounce time period expires; otherwise it is ignored.
