Cause
Linkflap threshold has been exceeded and the port has been taken down due to linkflap configuration
Resolution
If there is an issue with the link that has caused it to go up/down too many times resolve the physical link issue.
If linkflap has been triggered prematurely  use the "set linkflap threshold" command in any command mode to increase the number of link flaps that will trigger a link flap action for the specified ports.
If you only require notification but to keep the port active then change the action using "set linkflap action"
