Speed LAG with 2 netgear switches GS110EMX and GS380EPP

[FrankVe]

Hi All,

I recently got me a nice set of switches.

Connected to the GS110EMX:

NAS (Synology DS923+) with 10Gbit port to 10Gbit switch port,

2x 1Gbit/s PC/Win10pro.

With this setup, I get a download from the NAS of approx 260MB/s. Or even more, but my PC with SATA 1 wont run faster.

So far, so good.

But if I connect this same pc to a GS308EPP (also 2x 1Gb/s) and connect it to the GS110EMX with a LAG (ports 1&2), I was hoping for the same high speed.

But that is far from true: it's maximum download in this case is 110MB/s, so the max speed of a 1Gbit connection.

I needed more ethernet ports (other NAS-es, pc's etc) and POE too, that is why I bought the GS380EPP additionally, reading it supports LAG.

So how do I get the higher bandwith of 2Gb/s (or close to that) with two ports?

Or is this not possible because the GS308EPP only supports static LAG? I hope not, because I wasted a lot of money then 😞

Hi @FrankVe,

Welcome to the community!

This needs to be reproduced and better consult our support team for help.

Well, the point with LAGs is that the max bandwith theoretically feasible (n times the link speed) can (and is!) limited by the number of MAC addresses involved for the connection. The max possible througput is limited by the single link speed, not by the theretical n time the link speed, e.g. 2 Gb/s with two 1 GbE Ethernet links - some systems show to confuse the network admins and the users.
