I've just seen this is a 12000 so I may be out of my depth. Is it XR?


If it was my 4500, I would do show int G4/0/3 capabilities to check my options, and look for the flow control capabilities. It is always possible that it does not suppport static configuration and the only option is "desirable". If that is the case, then it depends entirely what is at the other end of the link.

I guess it is XR then, and I really cannot help you. Sorry.
