Failed To Establish ieee 802.3 ad connection synology

[CGameDev]

Hello Guys, so i setup Link Aggregation on my Synology NAS and I got that error message under network status, can anyone tell my why, or did i configure something incorrectly?

Are you on a managed or unmanaged switch?

[CGameDev]

Unmanaged

LACP requires a managed switch.

What option should I use?

None of them? Even with link aggregation, each connection will still be limited to 1Gbps. Unless you're in an environment where you know you need it (which it doesn't sound like you are), it won't help anything.

Well, I need the bandwidth for when an updating my Plex TV-Shows and Movies and more while others are streaming from Plex. I constantly ran into issues managing files on the NAS whiles its doing something else.

Not what you want to hear, but this is why I moved to 10Gbit.

It is not working because 802.3ad (LACP) works by having two devices communicate with each other and negotiate how the logical channel should work.

Since your NAS is sending out negotiation packets but is not getting any response, and as a result it fails to create the port-channel. Both sides need to be configured to use LACP in order for it to work. You need a switch that also supports LACP if yo want to use that.

It depends on what you want to achieve.

This feels like an XY problem.

I see. In that case you probably want adaptive load balancing. However, I strongly doubt this is the actual issue.

1Gbps is more than enough for streaming movies. My guess is that your bottleneck is somewhere else. For example if you use Plex it might be that you videos are being transcoded, and if that's the case you are probably running into a a CPU bottleneck, not a network bottleneck.

 

Netflix's Ultra HD bitrate i around 15Mbps.

You could have over 60 people each streaming a Netflix-quality 4K video from your NAS before you ran into bandwidth issues.

In before video snobs talk about how 15Mbps is low while ignoring the fact that you could have really bloated 30Mbps videos and it would still be enough bandwidth for 30+ streams, far more than home users need.

 

 

Please describe the issue you actually have and maybe we can help you solve it.

I am 99% sure 10Gbps networking would not solve his issues since this does not sound like a bandwidth issue.

1Gbps is more than enough for streaming videos from a NAS at home.

to mean "copying files to the server, while people are streaming from it" - which is exactly what I upgraded to 10Gbit to fix.

Good point. Hopefully OP will explain what the issue is he trying to solve is.

If it the way you describe then adding another gigabit link in adaptive mode would probably solve the issue in most cases, although a bit unreliably.

Leave all the NICs independent, use one for the Plex client and another for file management. It's less than ideal, but it's a solution you can implement for free with the equipment you already have. Just remember to give static addresses to all the ports you plan on using.

 

Either that or you'll need a managed switch. (If you go this route, get one with SFP+ ports so you can do 10 gigabit in the future.)

Added the second suggestion.

That's also what I did before upgrading to 10Gbit.  

 

I actually went in stages, first to a the spare Gigabit port on my motherboard (its a PC rather than an off-the-shelf NAS so had two ports already) then to a 1Gbit switch with two 10Gbit ports, DAC from the switch into my NAS and the main machine I would be moving files from in the copper port.

 

I then moved to a multi-gig switch before eventually moving up a tier to one with more faster ports (they're all in my sig)  as I knew I would be getting Gigabit FTTP (hopefully later this year) which would add yet more contention, plus I wanted more than one client to be able to copy to the server and didn't want the mess of another network, another switch or multi-port NIC and a ton of extra cables.

Moving to 2.5Gbit is probably a decent compromise, but I wanted to go all the way as some of my storage is SATA SSDs.

I actually have LACP on my router so that once I get FTTP I can concurrently use the 5G backup though will likely replace that with a 2.5Gbit capable model.
