How to Set Up Link Aggregation on a Synology NAS | LACP Tutorial

This tutorial focuses on how to set up Link Aggregation on a Synology NAS (LACP). By utilizing this, you're able to set up a bond network interface and either double or quadruple the bandwidth to and from your Synology NAS.

Great video Frank. You do a great job of making tech simple for others.

Your disclaimer at the beginning of the video, upto about 2:30 minute mark, is really important that is gotten wrong very often on the internet. Link Aggregation of two one Gbe does not give a single machine 2Gb access.
Great explanation.

Nice Video, tho right now I think Synology should make 2.5GbE a standard on their DS+ lineup

You really don't have to go and reset the NAS is you get into an issue with the LAG. Only the Bonded IP is no longer available. So, just remember which port you had connected first, move the cable on the switch, if needed, to an un LAG'd port. Then you can access the NAS through the original IP. The only reason this would not work is if you changed the Bonded IP to the original IP of the NAS.

Is it necessary to have switch with link aggregation feature or just any switch is fine

[perfectposes]

Where do i get that IP address to put in Manual configuration ?

[Kittyburgers]

I'm wondering what I should set up first, the link aggregation on my router (many ASUS routers support this) and then configure the network in the Synology control panel? Or do I just plug in the two network cables to the router, configure the link aggregation (IEEE 802.3ad) then turn on the link aggregation feature within the ASUS router?

I have had success by removing one of the network cables to gain access back to the NAS without resetting it.

Great video. user informative as always! I know several places were this is utilized in production!

Thank you for your great help!
i want to ask, i added a SFPD card, is it possible to make a Bond with native 4 cards and another different bond with SFPD card with mac adddress?
You have my like!

I'm a tad confused.

1. In UniFi Network, when you select Aggregate, it says "Make sure to enable port aggregation on the downlink device first before enabling it on this device."
2. In Synology, when you create Bond, and highlight the "i" button next to IEEE 802.3ad Dynamic Link Aggregation it says "IEEE 802.3ad LACP must be enabled on your switch beforehand"

So which one are you supposed to do first exactly?

I have the old Cisco SG300–10. I followed your advice to set up on my DS920+. thanks😁

[TheTF]

Thanks for the great explanation. Could you just setup the aggregation on the switch before you setup the aggregation on the nas?

[StringerBell]

This feature is awesome in theory but absolutely not useful in practice. Besides the "failsafe" backup if the cable goes wrong (something that happens ) there is no practical reason to have two 1 gigabit bandwidths when the NAS HDD can only read/write at 100-130ish mb/s . Even if you RAID, you still won't reach the bandwidth to use this.

I just bought a Synology DS 723+, and I don't have a switch. I followed your instructions but used the automated version for creating a bond and took a chance to implement it by connecting both my Gigabit cables to the router I have from Bell Canada.

It seems that everything went fine, and the good news is I didn't get locked out of my NAS ;-) The interesting thing, however, is that my browser auto-refreshed when I implemented the bonding, and now I am getting a warning that connection to the NAS is "not secure" and Chrome is showing the https in red with a strike through.

Should I be worried that somehow my NAS is now insecure and "went public" on the entire internet so anyone can highjack it?

[jaffaralbaroudi]

Hi, What if we have a SHA cluster? Thanks

[mzdial]

Just bought a DS920+ and you explained this perfectly. Appreciate it!

And this video is another example of how confusing this subject is for people trying to learn. One company calls something one name while another companh calls that same thing something else. We really need to get the industry to a standard of terms and then simply define those with an across the industry standard. The confused terms are Bond, Bridge, Link, Team, Group, LAG, and LACP, just to name some of the confused terms. It is really confusing lately since more people have been looking for ways to increase their home speeds using old enterprise equipment. That same equipment that was made for the combining of multiple NICs to get the faster speeds but made very difficult for the home user to replicate.

Do I have to use a different static IP to the one I have currently assigned for my NAS?

My UDM pro has a fixed IP assigned to my synology at the moment so can I still then assign the same IP on the synology setup for the Bond or is that going to mess it up?

I am tempted to just play it safe and assign a new IP (although fixed) that is not already allocated to a client. The other way I was thinking is giving my synology a random IP through DHCP so it looses it’s fixed IP that I want to then reassign through synology settings.

Thanks for the video !

Great video, thank you. Do you know if latest update to SMB multiple channel is better now to setup than link aggregation?
