Hello,
There is a way to check a cable with uplink active?
I have a device that negotiation 100m but is gigabit.
I think is cable, but i’m not on customer site.
So i can remotely access ti rb4011 and see port is running but 100m (not 1gb).
I try ti click cable check but tell me link Is active (no lenght no open circuit).
The cable tester only works with the cable disconnected.
If the link works, the cable cannot be tested. Only with a special tester. Check whether the auto-negotiation or manual is set.
Do not forget to turn on the safe mode when working remotely.
