Model: Archer AX11000  
Hardware Version:
Firmware Version: 1.1.1 Build 20200716 rel.84595(4555)

I just got an AX11000 for a review purposes and I cannot get the Link Aggregation to work with Synology DS1019+ NAS. 802.3ad definitely does not work. I cannot reach Synology after turning the AX11000's Link Aggregation on, even when I created a completely new Network Bond on DS1019+ for 2x1GBit.

Did anyone find a solution?

NAS is connected with 2x 1GBit to AX11000 to correct ports (LAN2-3). NAS shows the bond (2x 1Gbit) working fine. I can see this when I DISABLE the Link Aggregation from the AX11000. As soon as I turn the link aggregation on from AX11000, I cannot connect to the NAS at all. This is a core feature for a device in this price category. You definitely want to up your LAN speed to 1Gbit to 2Gbit to serve multiple devices in the LAN from the NAS.

I had no issues with Asus RT-AC88U-router. This certainly does not bode well for a 400€ device like AX11000.

Check that reference and see if it can help.

Remember that TP-Link products support only L2 LACP - static Link Aggregation.

So, look at the NAS link-aggregation settings and see if there is such an option to configure.

Static LAG or Balanced XOR are other link aggregation protocols to try on the NAS end.

I've found a reply but obviously the issue is not solved due to the lack of the feature being supported.

802.3ad is from year 2000.

It is needed for being able to use a single NIC/MAC Address for double speed data transfer between two devices.

XOR is only useful if you have multiple NIC/MACs (= multiple devices) that are accessing 

But if you eg. have NAS that's being connected to a ROUTER, you will NOT get 2Gbit/s between them with XOR. Instead it's just 1Gbit -> the link aggregation does not do anything.

What about the Static LAGG option, do you have that one in you NAS settings (it maybe named like Load Ballance for ex.) ?

@Ivaylo But load balancing is about routing different devices to a single source? It's not about dividing the load between multiple links over single NIC?

So device #1 would use "link 1" and device #2 would use "link #2" to access the router. AFAIK that's what LOAD BALANCING is = "2x 1Gbit/s"

Link Aggregation (802.3ad) is about linking two physical paths between eg. NAS and router -> 2x 1Gbit/s = 1x 2Gbit/s

By definition Static LAGG is defines as - "Balances outgoing traffic across the active ports based on hashed protocol header information and accepts incoming traffic from any active port. This is a static setup and does not negotiate aggregation with the peer or exchange frames to monitor the link. The hash includes the Ethernet source and destination address, and, if available, the VLAN tag, and the IP source and destination address."

Nothing is stopping you from trying that setting if you have it.

Synology DS1019+ offers the following options:

  • Adaptive Load Balancing --> "Does not require any special network-switch support and can connect two different switches."
  • IEEE 802.3ad --> "Dynamic Link Aggregation Used for connecting the switches configured as Dynamic Link Aggregation (IEEE 802.3ad LACP). DOES NOT WORK WITH AX11000 which is the issue!
  • Balance XOR --> Used for connecting the switches configured as Static Link Aggregation (IEEE 802.3ad draft v1)
  • Active/Standby --> It provides fault tolerance only.

    So which do you refer to?

I would try Adaptive Load Balancing or Balance XOR to see if that can achieve the goal - see that thread.

Those do not function as 2x 1Gbit/s for a single device. Instead you need multiple devices that can then benefit from the link aggregated speeds.

Active Load Balancing & Balanced XOR
 

  • Device #1 can access NAS on 1Gbit/s
  • Device #2 can access NAS on 1Gbit/s


What I am looking for

  • Device #1 can access NAS on 2Gbit/s


This requires a switch to be connected to the NAS that supports the link aggregation and that has faster than 1Gbit/s single links available to push the 2Gbit/s data stream to my computer in the LAN from the NAS.

Got it.That's the limitation I was mentioning about. TP-Link devices only support L2 LAGG. You are targeting IEEE 802.3ad (Dynamic) Link Aggregation (LACP, 802.1AX) which unfortunately is not supported.

Here's the tipical scenario.
