GS310TP - Autonegotiation on g8 to 100FD with a 1000FD capable cable and device
Hi, To my shame (after probably 4 months operating like that) I have noticed that a port (g8) is negotiating 100FD towards a device which happens to be the Router of my home WiFi mesh system (ano...
Ok, so just to conclude on this topic for anyone who might read it latter.
I did a software upgrade to 1.0.1.2 and tried again with my MacBook and the 10GbE adapter and now I'm getting consistently 1000FD.
My guess is that something got in a strange state and the upgrade fixed that. I have tried to plug/un-plug the cable multiple times and everytime it worked as expected (auto negotiation at 1000FD).
If other ports are reliably negotiate to GbE and just this g8 does have an issue, it might be small hardware issue.
In general, most problems speed negotiation are caused by cabling and wiring
Just to rule that out I have just done a test with a 3m patchcord connected to my 10GbE USB-C transciever to a MacBook pro.
I've got 1000FD on all ports of the switch except g8 which reliably stays at 100FD.
So I'm leaning towards a small hardware issue idea as well.
I will do the software upgrade as well just to be sure and if things look the same I will probably ask for RMA.
