This looks like one of the following:

1) Cabling problem to radio
2) Problem with the radio ethernet phy interface
3) Problem with the switch ethernet phy interface

You can perhaps try to troubleshoot by looking at the 'show controller' command 
output for the interface.  I don't know on this platform, but it typically 
reveals underlying details of the physical link layer that are not always 
promoted to 'show interface' outputs.
