Hi all,   I just faced this same problem on a WS-C2960X-48FPS-L running 15.0(2)EX5.  The problem began after a reboot to enable sdm prefer lanbase-routing.  No SFP's in use..  A hard reboot resolved it for us too.   

This is link broken, or no longer available? I'm facing the same issue right now, that was stated above.  My uplink port to our router is configured as a switchport, but I would like to set this as the NetFlow destination.  Is this possible? Thanks,C
