Have a S8 that has multiple 10Gb mm fibre ports that are Flapping like crazy - issue to do with with poor cables currently being investigated.

Problems is that no matter what I configure the linkflap paramenters to be I can not get the currentcount to increment and linkflap to generate an action, even though the port is clearly going linkdown and linkup. You can see this in this on the console, Netsight traps and topology changes.

The changes are occurring roughly every second or mutlples of seconds. Sample of the config below where I've tweaked the settings to 2 actions in 60 seconds to give more than big enough scope to capture an event:
