The Interface Restores to Be Up Within the Aging Time. Can a Switch Detect MAC Address Flapping in the Remaining Aging Time?

By default, the aging time of flapping MAC addresses is 300 seconds. If the error-down auto-recovery cause mac-address-flapping interval interval-value command is used to set the recovery delay to be smaller than the aging time of flapping MAC addresses, the interface restores to be Up after the recovery delay and when the MAC address does not flap. During the remaining aging time, the switch does not detect MAC address flapping because the aging time is not reached. To detect MAC address flapping, you are advised to set the interface recovery delay to be larger than the aging time of MAC addresses.
