Wow... been calling myself a network/sysadmin for the better part of a decade and learned enough from this video to feel like I've gone back to school.
You helped correct some missunderstandings I had about how to do bonding, and I was able to correct my configuration as a result. Thank you for the clear and easy to understand explainations
Very interesting. It's nice to see that someone has a functioning network. I've been having a tough time lately buying network switches. I've purchased two new ones in the last month and both were defective. I bought a Mikrotik css610-8g-2s+ and a TP-link ( I can't remember the model number) and both devices had the exact same problems. The Mikrotik switch took about 30 minutes to access the admin page, and when I could access it, it tossed up a network connection error. When it finally worked for a short time, it wouldn't save the configuration. After about an hour of frustration it finally stopped working altogether. The TP-link switch did the same things as the Mikrotik switch. The TP-link switch would take 10 minutes to start up and it quite working as well. I guess I'll start looking at ebay and maybe I may find a switch that actually works?
Wow... This is the first I've ever heard something bad about a Mikrotik. Where did you purchase them - were they from ebay? I know counterfeit switch hardware is actually a pretty big thing. Maybe they weren't authentic? The HPE/Aruba are pretty solid, though they get expensive if you need 10GbE as opposed to Mikrotik.
@@HomeSysAdmin I bought the Mikrotik and the TP-link from Amazon. I was surprised the Mikrotik switch failed, they are known for making quality hardware. I've been hearing quite a lot lately about counterfeit switch hardware being sold on Amazon and Newegg. If one or both were counterfeit, I'm not sure how to tell the difference. Counterfeiters are getting quite good and creating products that look identical to OEM devices. Maybe both devices were counterfeit?
Maybe. I don't mind the commands and I keep notes so I'm not having to memorize things. I find I learn how things work "under the hood" a lot better with command lines rather than any kind of interfaces, even if basic terminal interface. It's a great option to have though!
I'd be interested to see the differences between the modes if you were using a layer 3 protocol built for multiple paths (sctp). Iperf supports it, but there's a bit of extra overhead to account for too.
This video is very interesting. To be honest I would probably never use the bond the way you showed it, since it looks like more issues than its worth it. Instead I learned that a bind exists, and looking at the options you showed I can see a nice way of getting either a backup connection, or a way to improve transmission in one way (uploading from a bonded server to a switch and then distributing data further). Though I wonder, is it worth using this kind of a bond to eg. connect a file hosting web server with multiple interfaces to the network, or will it be better to just use routing as load balancing.
Unless you're trying to transfer a single large file (one connection) like I am, it's probably best to use the LACP method for the web server example - which would also handle backup/redundancy.
I didn’t know mode 4 can’t use both ports for a single thread. I will change to mode 0 and modify my Catalyst switch to use straight etherchannel and not LACP and see what happens to my file transfer speeds.
Hi There, I have 2 dell r720 running pve 8.2.4, connected by 2 1gig links to a cisco 3750 switch. I can get one pve to connect to the switch using lacp for the bond0. the other pve won't connect. same configuration for both bond0s. If you want more info let me know thx
I have a question. Almost all routers have a single port wan. My problem is I have two internet connections one is a backup connection. I know I can use a Pfsense router to do dual wan. however is there a simpler way of doing the same thing? The other problem I have is one of the connections is comcast and one is ATT DSL. I use the ATT DSL as a backup.
@@DiyintheGhetto TP-ER6020 is what I'm using. They might have others I don't know about. BTW - I think NetGear also makes dual-WAN routers, but stick with their "blue/grey" metal case professional-grade stuff, their "plastic case consumer-grade" stuff tends to be junk.

Props for remembering to save the switch config.
This is the only video on this subject that actually does some practical testing. Excellent work!
Very good video, thank you, Sir!
High quality content, good job!
Thanks! 🙂

To be honets, using nmtui is much better approach, nmcli is hard to get around because need to keep a lot of information in your head

isn't it easier to use nmtui?

TPLink among others make a dual WAN router. The one I have has 3 LAN ports to go with the dual WAN ports.
@@bricefleckenstein9666 thank you very much I will look into it. Do you know which model or model number I should look out for in tp-link?
