To follow up on my own question: the optics do what the router instructs.
However, "shutdown" does not guarantee the router is doing what you
instruct. :-)
OSA measurement confirms this unexpected behavior. I have a case open with
Cisco to investigate optics turning on/off when router port is in a
shutdown state. (C6880, SUP2T, 15.2(1)SY1a)
