Hi,

Just as a heads-up, apparently GE/10GE 'link-mode full-duplex' 
configuration on M/T-series routers has no effect, the interface stays 
with auto-negotiate.

Some versions of current software report warnings on commits to syslog 
but these warnings are being removed.  The configuration syntax is 
still be supported but it's a no-op.

I wonder if there is a valid deployment scenario where you will want 
to force full-duplex instead of doing auto-negotiation.  Now would 
probably be a good time to start talking to your local Juniper reps 
:-)
