Greetings,
I’m a home user with a simplistic network. I’m trying to set up a 2-port/1Gbit LACP LAG between a CSS610-8G-2S+IN and a Synology DS620slim NAS. When attempting to transfer a 10 GB file from the NAS to two different computers at the same time, only one port is ever utilised on the switch, thus capping my speed at 1 Gbps.
However, if I set the Synology NAS to use Adaptive Load Balancing, I am able to utilise both ports, thus giving me a transfer rate of 2 Gbps.
What could be the reason for LACP not utilising both ports on my switch/NAS?
This is my simple network:
EdgeRouterX: (192.168.1.1)
Synology NAS: (192.168.1.3)
Mac Mini A: (192.168.1.4)
Mac Mini B: (192.168.1.5)
CSS610-8G-2S+IN: (192.168.1.50)
I’m not using VLANs and my devices have all statically assigned IP’s on the same subnet.
The switch is running the latest release candidate: 2.13rc25
In SwOS I have set the LAG mode to “active” for ports 7 and 8 and in the “Trunk” column I can see a number “1" and the “Partner” column shows two identical MAC addresses when I enable LACP on the NAS.
In Synology DSM, the “Network Status” shows “2000 Mbps, Full duplex, MTU 1500".
On the surface, everything appears correct, so what am I missing or have a misunderstood how LACP works? For now I will just have to stick with “Adaptive Load Balancing" which seems to give me the full transfer speed.
Thank you
