802.3ad - how to use with Synology NAS

RouterOS General
1

I have an RB493G and I’ve connected up my Synology DS412+ to two of the ports. I’ve created a bonding interface with the two Ethernet ports and added that to the bridge.

So far, so good.

Where things fail is if I set the NAS and the bonding interface to use 802.3ad. In short, it doesn’t work. The device disappears off the network.

I get the feeling that 802.3ad is an asymmetric protocol and that both sides are trying to be a “client” and it’s not working.

At the moment, the best I can do is configure “active backup” mode on the 493 side and disable 802.3ad on the NAS. That, at least, allows the thing to be seen as long as any one of the two plugs are connected, but I had hoped that with 802.3ad I’d be able to load balance between the two ports.

Ok, I am certainly willing, but I think I need some more information. Can you suggest which knobs I need to twist to make this happen?

I do see a mention of STP in the bridge config, and I can set that to ‘stp’ (it was none), but that’s one level “up” from the bonding interface that ties together the two links from the NAS.
