Most people tend to just plug their network card in and expect it to go. However there are some of us who are always tinkering and trying to get the most out of something as we can. And in this post, I am going to touch on a few things that I have had to educate myself on as I went along.

This day and age we find ourselves looking at SMB 3.0 Multichannel so that a computer can transfer information over multiple network connections at once. In the old modem days, this method was called “shotgun” where you had 2 modems and 2 phone lines connected to an ISP that utilized the shotgun technology. This new SMB 3.0 Multichannel was released with Windows 8.1 and is supposed to be made even more easier in Win10. The drawback to this is your hardware has to have certain features and enough cpu cores to handlethe divided communications. This is on both the sending and the receiving computers. With my home lab having older workstations, they seem yo have the features but I have never had any luck with it. I have seen in quite a few placea that SAMBA can be setup to use the SMB 3.0 multichannel and it works well at least when the server is Linux and the client is Windows. When my quad Intel network cards get here for my PeppermintOS 10 Respin file sever, I may dig into this with the PeppermintOS 10 Respin clients…

Anyway, the project I am tinkering with right now is getting 802.3ad LACP aggregation working between 2 workstations (HP Z820 and a Asus P8P67 WS Revolution) along with a TP Link TL-SG2424 managed switch. They performed this task while they were both loaded with Win7 Pro, but M$ broke that functionality with Win10. With PeppermintOS 10 Respin, it is easy to bind the network interfaces. However, the simplified NetworkManager sets the bond at Transmit Hash Protocal to “layer2”. It seems that “layer2” only transmits over single network connection. So it seems that I have to change to “layer3+4” to get the Win7 802.3ad LACP aggregation back. I am also going to need to change thr LACP setting from slow to fast also. I saw ChrisTitusTech talk about netplan, but I also saw that the netplan on PeppermintOS 10 Respin turns over control to the simplified NetworkManager.
