Looks good. Are CLI changes already available to isolate/unisolate link manually ?

If a fabric port repeatedly and rapidly transitions between the isolate and unisolate states, resulting in instability, the algorithm places the link in a permanent isolated state. Currently, the threshold for triggering this condition is when a link flaps three times within a two-hour period.
Recovery from this state requires manual user intervention via a CLI command:
config fabric port unisolate -n asicX --force
