This feature introduces a configurable delay for flushing the MAC address when the network interface goes down, reducing unnecessary MAC address flushing during transient link failures. By default, when the link goes down MAC addresses associated with the link are flushed immediately. With this feature MAC address flushing is delayed by the configured time when the link goes down and if the link comes up before the configured timer elapses MAC addresses won’t be flushed from the forwarding table and the timer is cancelled.
