HL15 2.0 network config

General
1

Just got a brand new HL15 2.0 and I going through the user manual to set it up, but I don’t seems to be able to get to the networking configuration.

the user guide says to Go to the applications in the top left corner. Go to settings → Advanced network Configurations.
But the Advanced network Configurations is not there.

what should I do to be able to configure the ethernet ports?

I’m not sure why you wouldn’t see that in the UI. There is a section a few pages later in the manual for “SETTING THE NETWORKING USING NMTUI” if you want to try that method instead.

Thanks for the info,

I was able to change the ip address of the NIC port with the nmtui command

Also do you know if the NIC can do 2.5Gb/s, the reason I asked is because I have a switch that can to 2.5Gb/s, but the 10Gb/s on the server only connect at 1Gb/s to the switch.

My understanding is that the NIC chip on the board is an Intel X550-AT2 and that that chip may not support the 2.5 and 5 Gb/s standards. Depending on your build, you could add a NIC that does. Or add a switch like the Mikrotik CRS305-1G-4S+IN and a couple of transceivers that do multiprotocol to sit between your existing switch and the HL15.

I have found a command to start auto negotiation for the NIC card that fix the problem

ethtool -s eth0 autoneg on

The X550-AT2 does support 1G to 10G connections and all speeds in between (10/5/2.5/1GbE) according to the spec sheet from Intel’s website.

Thanks for the information, this what I found also

I found the reason why I can’t auto negotiate at 2.5Gb/s, it’s done by design.

Here what I found;

You can’t auto-negotiate to 2.5Gbps with the X550-T2 because the default configuration, due to its design, does not advertise 2.5Gbps or 5Gbps speeds during auto-negotiation. To enable it, you must manually configure the network adapter to advertise these speeds using the appropriate command-line tool for your operating system, like ethtool on Linux.
