MS510TXPP not getting more than 1Gb on 5G End to End
EDIT: Tried posting yesterday, doesn't show up in the board. This is my 2nd attempt. Hi, I have two switches in two locations, CAT6A copper between them in the 10GbE port approx 35m cable lengt...
It's a true multigig adapter, that's certain. I found an old mellanox 10G card with a twinax that I inserted into another server (and in SW01) in the offsite location, and the iperf3 test was up to 4,7gbit. I did the same with the client, on SW02. So I've excluded the cable, nic and the server as a cause (in both sites). - Which leaves the switch interconnect.
Physical Mode 10000 Mbps Full Physical Status 1000 Mbps Full
So you mean that Physical Status reflects the actual speed?
I checked the 5G port for the server (which I just benchmarked at 5G) and it reports the same:
Physical Mode 5000 Mbps Full Physical Status 1000 Mbps Full
If the cable was bad, wouldn't there be a lot of transmission errors in the port details?
And if the cable was bad, wouldn't it negotiate a lower speed (i.e physical mode)?
Is there a way to "force" lower speed on the port?

This is prohibited by the IEEE standard my friend - autonegoation is mandatory from GbE and up.
Open a ticket with Netgear please.
Already considered a firmware update to the current 6.7.0.50 btw.?
I hadn't considered it, but I did the upgrade now. Besides a really annoying "You _must_ change the password from the default" the port status now reflects the negotiated speed in physical status. (you can remove it by using inspect element and deleting it)
My environment is now like this:
server1-----5G-----<SW01>----10G----<SW02>-----5G-----Client

server2----10G/

And I'm getting more speed now after the upgrade. Not exactly 10G, but a lot better than before (this is client to server2 (with the mellanox 10G sfp card)). Good call on the upgrade schumaku

So now we can conclude that the switch interconnect is at least at 5G speeds.
I reran my test to Server from Client, which should be able to give me 5G speeds:

I thought I might be CPU constrained so I ran a test between server1 and server 2:

Locally, using the same switch, I'm getting 4gbit+. Over the interconnect, it's 2,8gbit. What am I missing?
