Hi folks, hi have a new RB4011iGS+ with problems on ether2/3/4. On these ports auto negotiation fails, it don't matter what kind of device i connect (server, NAS, laptop, switch...etc). Link is up only at 10M half duplex.
Tried different patch cords wich works on other ports.
Firmware: 6.46.1
Log:
dec/17 16:54:37 interface,info ether2 link up (speed 10M, half duplex)
dec/17 16:54:37 interface,info ether3 link up (speed 10M, half duplex)
dec/17 16:54:37 interface,info ether4 link up (speed 10M, half duplex)

if i uncheck/check Auto Negotiation on Interface properties link is up at 1G until reboot

Try going back to version 6.45.7.
I'm not sure, but in my opinion there is a difference in the operation of the interfaces with v6.45 and 6.46. Let's check.

i have been tried, same thing...

Did you try both versions? Maybe it is a hardware fault, at least for me RB4011 has no issues.
