The problem im facing is that the router cannot establish a link to the switch, eventhough looping back the fibre that connects to the switch, the router was able to recognise that loop. I have done the necessary fault finding and eliminate the fibre as the problem.
Im using the switch as a form of repeater as the SFP module is limited to only 70km.
Im a novice to this and appreciate if someone could assist me in solving this problem OR point me to the right direction.
