 Tom here from Lauren systems and Unify has released their six point zero point two zero unify controller software But stop don't upgrade it And this is one of the reasons that I'd like to do testing and then do some videos about whether or not that testing went Well, and I do appreciate all the people said hey, Tom I kind of wait for you to tell me whether or not I should upgrade my controller because well I don't have the network engineering time to spend Re-engineering network because I have something else to do I completely get it and I'm telling you don't upgrade That's one of the reasons of doing this video. This is very fresh information I guess you could say some of these forum posts are only hours old But I wanted to get the word out there for people who are Feeling as though they should jump on that six point O version of the unified controller So we're gonna say not to upgrade it if that's all you want from the video do that I'm gonna leave all the links on below if you want to continue on further great I'm gonna talk about some of the details and some of the mitigations that appear to be working We're still like I said Solving some of this and waiting for a unified response on it because that would be interesting Maybe they have a patch coming soon. I really really hope they do and if you can click the like button and first If you'd like to learn more about me or my company head over to Lawrence systems calm If you'd like to hire short project, there's a hires button right at the top If you'd like to help keep this channel sponsor-free and thank you to everyone who already has there is a join button here for YouTube and a patreon page your support is greatly appreciated if you're looking for deals or discounts on products and services We offer on this channel check out the affiliate links down below They're in the description of all of our videos including a link to our shirt store We have a wide variety of shirts that we sell and new designs come out well randomly So check back frequently and finally our forums forums dot Lawrence systems comm is where you can have a more in-depth discussion About this video and other tech topics you've seen on this channel now back to our content So over here in the unified forums is the unified network controller six point zero point two zero with look at all these New features improvements and bug fixes. They need another one known issues Vlands beyond UAP Where list down links may not have connectivity creating VPNs and UDME results and commit errors That's the least of your worries here. Let's dive into it. So me and Riley Chase I'll leave the conversation poll up here. We started talking this morning now Riley is the owner of hostify I've reviewed the product before the I would say Riley and the hostify team is the foremost expert on Unify hosting because they do it at scale and I really like their product that also means people that are using them to manage and Can take care of all the updates they do their own testing as well and because of the volume of clients they have they get a lot of insight and They're really recommended don't do it so me and Riley talked this morning And we're gonna talk about a few forum posts now obviously if you just go to the hostify Twitter account They've been tweeting don't do it. I want to help get the word out. Don't do it So we can get that out there So the first one is there's some type of mystery Vlands that get created now This is some type of bug that appears to be Creating an extra VLAN that causes a Issue with connectivity and breaking some of there So there's a few people that have found kind of mitigations for it Just by deleting this VLAN zero that it creates this extra that you didn't create VLAN and by doing that They're able to get things online most people just seem to be rolling back and that's kind of an easy solution The problem is once you roll up to six it pushes out some settings that causes the devices start meshing to each other so there's two forum posts in Reddit that I'll leave links to where people have some mitigations But this one kind of made the most sense to me over in the unify forms leave a link to this one here and This person figured out a way to do this without upgrading So essentially what they decided was going on well Like I said did the time looked at some network engineering and this is a forum post I have not validated this is true, but feels pretty true and people talking about mitigations here That they found that the device the unify access points start meshing to each other Even though they have a wired backhaul So the unify APs have the ability to mesh to each other and like an isolation mode So if you have one that has power, but for some reason loses its backhaul back to the switch It can actually still be working as a mesh unit. It's a great feature that unify has It's apparently broken in version six because if you start meshing something that also has a backhaul You create a loop and then spanning trees should be fixing that not cause a broadcast storm But that isn't happening and that's something that's apparently wrong in the new version So they have some mitigations and fixes for this now for people that are stuck in this broadcast storm This actually is what creates the challenge. So even though, you know how to mitigate the broadcast storm a broadcast storm Well, it's a storm and it breaks the ability for you to log into these devices So sometimes you have to start rebooting switches to kind of stop the storm from happening So you can start getting into the devices or start offlining your access points Obviously, this is extremely disruptive if you have a bunch of users and No one, you know, you it should be something almost transparent where nobody knows what you're doing that way They complain like what do we pay you for? We don't have problems and etc This is all those times your IT is like, why do we pay you now? We have problems type situation You know, sometimes IT is a thankless job occasionally But this is all those times where you will definitely get the user's attention if you push this update in your environment I'm hoping you see this video before then you go wow I know how to mitigate it and you can I don't know and I may play around and do a follow-up video There's some pre mitigation like before the upgrade. Can I just mass disable it? The problem is I need to be able to do this on all the sites we host So that seems kind of tedious and this is we're talking for people like it hostify because Riley does things like looks at the database and flips switches and database at scale as opposed to trying to go through each menu And do it which is obviously really tedious and so there's going to be some You know tooling around that we're going to have to do to look at this for people like myself that want to play with it For people that just go I want this to work. What should I do wait? There's nothing wrong with the old five version controller. It works great. We're not experiencing any trouble with it it's quite stable and Yeah, so I'm not upgrading anything that is mission critical. We do have other lab systems So I may do some more testing with to see you know how the bug progresses and of course once again We'll wait for an update from unify that hopefully just flips those switches or unflips them I guess which way is it going is kind of the curiosity So I'll keep diving into this and I'll leave links to these forum posts and don't worry. There's more people are still As this upgrade comes out and it suggests that you upgrade or people who do crazy things like tell systems to auto update I auto update for security on like my Linux systems because I feel very comfortable with that We do have auto update on Windows systems because I feel comfortable Well, it's comfortable. She could be with Windows, you know, that's a damned if you do damned if you don't you're Insecure if you don't and well Windows updates. That's yeah, it's not like this is updates are unheard of problems in the IT industry They're actually the biggest reason updates don't get done in certain name of any company and you'll find them to be Yeah, the reason that we're always busy in IT why there's an endless amount of work for us So don't upgrade Hopefully you don't have auto upgrade turned on and if you do rolling back seems to be a solution that works But sometimes you may have to do some reprovisioning best of luck I'll leave links to these forum posts and go from there.
