Hi Joe,

I'm not sure what I'm looking for there? The interfaces are running at 
gigabit rate and there are no errors logged, so the configuration 
appears to be OK, to me at least? And two similar systems with similar 
cables behave the same, which seems to eliminate specific hardware/cable 
faults? The cables are cat 6.

Thanks, Dave
