Hardware Version: V1
Firmware Version:

Recently, we got a case reported by one end-user that he failed to connect his Synology NAS DS918+ to the Archer AX6000 with Link Aggregation enabled.

 

As per customer said, the network diagram is Modem—Archer AX6000 (port 2&3)—(port 1&2) NAS (Synology DS918+). With his smartphone connected to the AX6000, he is not able to access the NAS unless he disconnects one of the two ethernet cables.

 

With further analysis, we solved his case by changing the Link Aggregation mode from “Adaptive Load Balancing” to “Balance XOR” on his NAS.

 

If you have a similar issue, it is worth a try to change the Link Aggregation mode to “Balance XOR”.

 

You can refer to the articles attached below to get more details about the Link Aggregation configuration:

Hello,

 

I have a DS1819+ and it doesn't have an XOR mode. What other solutions does TP-Link provide? It is not normal for TP-Link to sell you a router with the link aggregation option, and then not work, or be compatible, with LACP.

 

Thank you!

Actually, to promote Link Aggregation should work with LACP Mode 

but it is not, please improve

 

- Option 2: Doesn't work

- Option 3: Work instead

@Solla-topee I also vote for this resolution. I ran into the same issue and now my NAS works only with Balance XOR setting. Thank you for looking into the issue.

Just tried to setup Link aggregation with my DS918 and the same router, same problem! and if you visit the tp link specs page for this router they clamed to support LACP 802.ad and it just doesn't work.
This is the second tp link product where I run into issues ...

Can you please point out where did you find the tp link specs page for this router they claimed to support LACP 802.ad? We may need to review that, thank you.

 

BTW, can we have some screenshot about the settings on the DS918 that you have changed, then we can check further?

It absolutely DOES 100% support link aggregation, BUT IT DOES NOT support LACP or port trunking, which is what you are trying to do with 802.3AD. You CAN USE 802.3AD port trunking on the NAS, given the caveat that you have switching equipment which can handle LACP & 802.3AD dynamic trunking.

 

In fact, I use a business class Cisco 100Gbe L3 managed switch & have a couple VLAN's off it, one to a HW VPN/firewall, routing to my home lab. QNAP #1 -gets a 2.5-Gbe for NIC 1, plus a apir of trunked LACP 802.3AD 2.5Gbe NIC's for multimedia and private LAN, then a combo base 10 RJ-45 & 10Gbe SFP+ connection on a third VLAN which incorporates an internal NAS side VLAN & an advanced virtual switch for containers, VM's and such. This last VLAN is for my workstation, NAS#1, NAS #2, Cloud Box #1, a Wireless AX EAP & a DIY TrueNAS ESXi JBOD for backaups. 

 

802.3AD Dynamic LACP Port trunking works 100% fine for me on both the aggregated 2.5Gbe NIC's & on the 10Gbe NIC's. The caveat is, as mentioned, you need switching gear which supports dynamic 802.3 & so far as I can tell, the only way to reliably do this is to run static link agg. to the switch, then setup LACP dynamic trunking from the switch to the NAS.

 

I can also tell you that if you keep an eye out, that you can often find pretty good deals on a QNAP QSW-2108-C, which is a L2+ web GUI/terminal managed switch that supports L3, 802.3AD LACP & offers 8x Base-T 2.5Gbe 4-speed RJ-45 connections, 2x Base-T 10Gbe 5-speed RJ-45 connections plus a pair of 10Gbe SFP+ connections. 

 

It will work with any device or equipment manufacturer, as long as the gear supports the standards & often enough you can find this or equivalent on special in the mid-200's. Not bad for 4x 10Gbe & 8x 2.5Gbe connections. Honestly though, it depends on what you are trying to accomplish. Most homes aren't designed or equiped to handle anythiing over 1Gbe anyway & most are nottlenecked on their WAN anyway. I have two seperate ISP's, business class fiber & one for residential fiber. Thus us why I have the switch pre-router, at the ONT. Those WAN connections get aggregated at the Cisco box & even with all new cat 6 ethernet & all AX WiFi-6 AP/EAP's, I seldom see any remote read speeds above 1.2 Gbps or remote write speeds exceeding 600-800 Mbps, even with gen 3x8 PCIE NVME disks that benchmark over 4x that with over 350k iops across the board. Not to mention that 802.3AD is very fickle & finicky on all consumer grade boxes, Asus, QNAP, Synology, etc.
