Is it possible to stack 2 qnap switches (QSW-M1208-8C)

English Networking
1

I have two qnap **QSW-M1208-8C"; I want them to interconnect them via port 11 and 12, and put it into a lag. (I know how to do this)

What i want to accomplish is that I can put 2 ports, 1 from each switch into a LACP.
Is this possible?

thanks in advance.

LACP and LAG are basically the same thing. This is different from Stacking. When you stack a switch, it acts as a single unit. For example, I manage a network at a hockey rink in Florida that has 8 Cisco’s stacked. Functions as a single switch.

LACP = Link Aggregate Control Protocol

LAG = Link Aggregate Group

A LAG uses LACP.

Hi, thanks for your explanation.
I use the lag on 1 switch. What i like to know, is can this be used over 2 switches.
For example, I connect my esxi host with 1 port to switch 1 and 1 port to switch 2.
Can I put both port in one and the same LAG?. So i create redundancy over 2 switches.

As far as I know, this is not possible. I’ve seen people ask similar questions.

A LAG is an aggregation of a link to give you a multiple of the speed of a single link. For exampling creating a LAG of four 1 Gb ports will create a single 4 Gbit connection. It does create redundancy but the traffic is all being managed by the switch. I’m not sure if there’s a way to do what you want with anyone’s switches.

I think you are right. I quess i want something that is not possible. Anyway, thanks for your sharing information.

Currently, QNAP supports Multi-Chassis Link Aggregation (MC-LAG) on certain models. I believe this is the solution you are looking for. You may refer to the official feature description at the link below. Hope this helps.
(Unfortunately, the QSW-M1208-8C does not support this feature.)

That is exactly what i am looking for. Thanks for sharing. Good to know that it is indeed possible. I will see if i can solve my needs with a workaround. otherwise I will (need) to consider to find me one of the systems that supports this.

I’m glad to see this is possible too! :smiley:

Very cool.
