GS724Tv4 - top speed 100Mbps

[joliveira-kbc]

Dear Community,

I have a GS724Tv4 which has the latest firmware version:

Product Name GS724Tv4 ProSafe 24-port Gigabit Ethernet Smart Switch, 6.3.1.34, B1.0.0.4
Serial Number 3H024B56002CC
Base MAC Address A4:2B:8C:06:3A:70

Problem: data transfers cannot go higher than 100Mbps. I tested iperf3 on a Hyper-V server, VMware ESXi and a Linux Ubuntu 16.04... Top transfer speed is always below 100 Mbps.

If I plug those servers directly to a computer transfer speed is always higher than 500 Mbps (depending on CPU and NIC).

Please, could someone help me?

Thank you.

Kind regards,

Jose

Hi Schumaku,

Problem was on Ubuntu's 18.04 driver - autonegotiation was failing. Setting up 1000 Mbits full duplex on nic settings fixed the problem.

Thank you for your help.

Kind regards,

Jose

The link speed on the ports in the data path indicate full Gigabit (Speed LED: green) or Fast (Speed LED: amber)?
