Looking to configure LACP on both my UnRAID servers.  They've had multiple NICs in them for some time but I had some trouble configuring bonding about a year ago and just let it be.  Are there any specific steps or order of steps recommended to get this working?  NICs are Intel X552's and switch is a Cisco SG350XG-24F.

 

** Dislclaimer:  Yes I'm well aware of what it takes to make use of more than the speed of a single NIC and yes I have a use case for it.  Furthermore, I'm equally as interested in maintaining and active/active bond for failover as I am for the bandwidth increase in certain situations.

So interesting to me how so few people seem to do bonding in UnRAID.  Bandwidth aside, just having redundancy seems like a no brainer.

I use to do it. Then I upgraded to 10gbe. 1 wire is better than 4!

That doesn't address my main point...redundancy.  I'm on 10Gb as well.

I use the remaing quad ports for failover if the 10gbe goes down. Which it did once. 

 

So, yeah, it kinda does.

 

lacp was straightforward for me, but the ports are all on the same card. Might make a difference but I wouldn't know.

I had an LACP setup once. But I was using a cheap TP-Link Managed Switch

You just setup the switch to "trunk/group" the ports. I used passive mode (which allowed the ports to continue working while the OS wasn't configured)

Plug in just one cable

Setup unRaid to use bonding in LACP (mode=4)

Start pinging the unRAID server (so you'll know if the network fails)

Then I plugged in the other cables, one by one, while the network continues to work.

 

I used to know the commands on Cisco IOS and similar...
