[nsp] undocumented CatOS commands

[Church, Chuck]

Does this command log any single move between ports, or does it just list flapping, which I would define as x number of moves in y amount of time between 2 ports?  Anyway, I've seen that same exact message on a 4000 running 6.x code, and I hadn't changed anything in the config to make it do that.  So maybe it's a default in 6.x?  Or a certain level of logging for the earl facility will do it?  Just a thought.
