Link flap detection enables you to set thresholds for the number and frequency of link state changes allowed on a physical port and to take action if the thresholds are exceeded. If the link state change thresholds are exceeded, a log entry is generated.
Use the Link Flap tab to enable or disable the Link Flap Detect feature. When this feature is enabled, it monitors the number of times a port goes down during a certain interval. If the number exceeds a given boundary, the port is forced out of service.
