I have a rb2011 with an ethernet port (7) often has "no link"
there is no way to turn it up again other than a power supply reset
I tried all possible negotiations on the port as well on the attached device ethernet
also a software reboot produces nothing positive (replaced cable of course)
On ether6 is connected an identical device , if i swap eth6 with eth7 , 7 is still down while 6 goes up
Not yet tried to move 7 to 8 (rb is on service at customer)
Some other rb2011 had this behaviour sometime but it is gone after a power cycle and never re-appeared
Is it a known issue ? is it definitively an hardware malfunctioning ?
