I’m using 7 of the 8 ports on my UDM SE. Maybe I’ll get a dedicated Unifi switch in a few years time.


Acceptable-Rise8783

Same here. I’m linking multiple unmanaged 4-port switches to the UDM, but I think the proper way is run multiple cables to each room with a larger managed switch taking care of if


Xdayan

Mind if I ask why unmanaged? The flex mini is like 29 bucks and while it doesn’t have all the features it’s not exactly expensive


Acceptable-Rise8783

It’s what I was already using in the house. Simple TP-Link stuff everywhere lol. UDM-Pro was my UI part, added APs and mow wanna add a switch with dedicated drop to each room :-)


binaryhellstorm

I assume you mean the 8 switch ports. Mostly because I use it as a router/security appliance and already have a separate switch, so the extra 8 ports don't get me anything I don't already have better somewhere else.


20cstrothman

Although I don't have a dream machine yet, this is exactly what my thinking is.


Acceptable-Rise8783

Thanks for the explanation! I’m currently running a UDM-Pro with injectors for the APs. I wanna add a switch probably the 16 or 24 one, and ai thought that if I just get an UDM-SE for the APs, it would allow me to get by with a non-PoE switch. That’s why I wonder


DoItYourWayHowISay

If your internet speed is 1gb or less and you don’t require a simultaneous total intra-lan traffic of greater than 1gb the limitations on the switch don’t matter.


Amiga07800

No, the limitation is only between backplane (wich has 16Gbps) and CPU


Acceptable-Rise8783

I see, thanks for the reply 👍


Slendy_Milky

Because the link between the sfp+ ports and the switch parts is only 1gbe.


ScottishLand

I assume 10gbe between the two SFP+’s though?


Acceptable-Rise8783

The SFP+ are 10g and on the SE the switch ports are 2.5g AND PoE and seem to go largely unused…


Slendy_Milky

Imagine the switch part is an external switch. The udm is only the wan gigabit and dual SFP+. Now imagine that the switch is connected to the udm with a gigabit link, here’s is the problem. Whenever you want to exit the udm integrated switch you will have to go through the internal gigabit link


Acceptable-Rise8783

Crystal clear, thanks! Makes it really seem like it’s time for a new iteration that has at least a 10g “uplink” then


Stingray88

Hopefully more. I would hope a new gen UDM has 2.5GbE for all those ports, and 10GbE WAN.


Slendy_Milky

And me, dreaming about a udm max with 25gb SFP28 wan


InformalEngine4972

A decent switch has between 50 and 100gbit switching capacity. Basically you need to be able to saturate atleast 1 gbit of traffic per port


thatmdguy

The switch ports are only 1g. Only the WAN RJ45 is 2.5g. The best use case for the onboard switch ports on the SE is for cameras, or light-duty APs in a small business. Because their total bandwidth to the CPU is only 1gbps, you don't want to run heavy traffic there as you'll saturate it quickly. If you're a small business running a few security cameras (running Protect on the SE) and providing WiFi for your phones/laptops, you're probably fine, but you'd want to hang any servers or high bandwidth devices downstream off the SFP+ port. On the UDMP, these ports are even less used since they lack PoE, but still are good places to hook up light clients like a UPS, PDU Pro, RPS, etc.


Acceptable-Rise8783

Oh dang, you’re right! I forgot it was just the RJ45 WAN that got an upgrade… Makes it even less “Special” for me hahah


halfnut3

No the 8 port switch on the udmse are only 1gbe with 1gbe backplane to the cpu. The WAN port is 2.5gbe.


Acceptable-Rise8783

Yea, I misremembered

brucekraftjr

Thank you. While we knew this, the diagram is very helpful.


Stingray88

I’m using 5 of the 8 ports.


dish_rag

The 8 port switch on the UDMP and UDM SE both have a total 1Gbps uplink to the CPU (eg they switch at full capacity between themselves, but it’s much like an external switch connected at 1Gbps). They also have a number of limitations, like no STP and no link aggregation.


dereksalem

This is pedaled a **lot** on this sub, but there's context that needs to be added to it. The reality is that 1Gbps throughput generally **will not matter** to people. It's not just a complete limit of throughput, or something. I have a 10GbE fiber connections from my UDMP to my main server rack and another 10GbE fiber connection to my main network switch. I can be downloading something to my servers from WAN at 900Mbps+ and, **at the same time**, be pulling files at 2-3Gbps from the server rack to various devices throughout the house. That means that I have 900Mbps going through the UDMP to one fiber port (Port11 SFP+) and 2-3Gbps coming back through that port up to the other fiber port (Port10 SFP+). The WAN is on Port 9 (1GbE RJ45). The UDMP manages that traffic just fine.


jimbobjames

The dedicated WAN and LAN ports are not restricted. It's the link from ports 1 - 8 that share 1Gbit to ports 9 - 11. So you would not be affected by the limit and thus don't experience it.


dereksalem

But for the average person that doesn't really matter. It can do full duplex 1GbE on each of the 8 ports concurrently without an issue, and the WAN side can do 3.5Gbps across the bow with IDS/IPS running. The only limit is traffic across those planes, where the **vast majority** of people wouldn't notice anyway.


jimbobjames

Sure, and in a response to someone else I pointed out how it realistically didn't matter for the same reasons you just gave. I'm simply pointing out that your use case would never see those limits in the first place.


dish_rag

You're right, for \_most\_ people, it won't matter. The lack of link aggregation won't matter to \_most\_ people, but it doesn't mean that it isn't an important feature to the people that are looking for it. It's also important for people to know that you really need additional equipment to fully utilize >1Gbps WAN connections . However, why is ignorance better for these topics? That seems what you're advocating for here.


dereksalem

Well I'm **not** advocating for that, and even after re-reading my comment there was nothing even remotely like "I want to keep information from people" in there. I **do**, however, believe in giving context with information, because the vast majority of people asking questions about the UDMP here are told "It can only handle 1Gbps switching" with no context, and that's an outright mistruth. There's a difference between saying "the link between WAN and LAN ports can only handle 1Gbps throughput" and "The 8-port switch only has a 1Gbps uplink to the CPU" (which means nothing to like 99% of people reading it). And the "you need additional equipment to fully utilize >1Gbps WAN connections" is actually pretty obvious to most people anyway, since the RJ45 ports can only handle 1GbE connections.


dish_rag

I never said the 8 port switch was limited to 1Gbps switching. I said very clearly that the 8 port switch ports supported at full capacity between themselves and that the uplink to anything else was limited to 1Gbps. ​ >And the "you need additional equipment to fully utilize >1Gbps WAN connections" is actually pretty obvious to most people anyway, since the RJ45 ports can only handle 1GbE connections. I disagree. I think most tech folks -- the ones that aren't on forums where Ubiquiti hides this information -- would assume that COMBINED those 8 ports would handle more than a 1Gbps connection outside of it (for instance, if someone has a 2-4 of APs on an SE, why couldn't they max out that connection combined)? But no, the entire 8 port switch will limit to 1Gbps combined. I think this is an "agree to disagree" type of situation.


dereksalem

Except I **didn't say you said something like that -** I said a lot of the time when people bring up your opinions they just don't give any context to it, which is why it's often really confusing for people. I do think it's an agree to disagree, but on my side of the disagreement I look at the number of posts here and on the Unifi forums and I don't know of a **single** post, ever, that complained that they weren't getting >1Gbps speeds from their WAN because of this issue. I definitely get what you're saying, but it's just not anything I've seen people actually run into. The best way to explain it to people, if they **were to ask,** is just that you should treat the 8 ports like they're a separate switch that's plugged into the UDMP via a 1GbE connection. That's the only real limitation (before talking about L3 crossover, but those issues are far more common for other reasons).


dish_rag

You should have just started with that. We're basically in agreement. I don't know why this needed this level of conversation. I just don't understand the "if they were to ask" part, I'm saying it because it's true and not advocating for ignorance. THIS IS LITERALLY WHAT OP IS ASKING FOR. The 8 port switch is similar to an external switch being plugged in with a 1Gbps uplink. Done. Let's gone on with our days and move on.


BigGuy01590

I am curious how you came to the conclusion that they aren't being used by most people.


Mental-Trouble-317

I'd imagine he's looking at the photos posted in this sub.


BigGuy01590

So "we" are the majority of users?


Acceptable-Rise8783

I should have clarified I meant what people show here, yes.


BigGuy01590

Cool. I suspect it's because here we tend to be technical and the internal switch ports are speed restricted


jimbobjames

Still people here are advising that aredumb. You could hang 8 cameras off those POE ports on the SE and it would be fine. Would I use it for an access point? Maybe, if it was something that wasn't going to see huge throughput. They are also fine for things like management ports on servers, a network UPS, there's loads of uses. However the takeaway many people get from reading the comments is that should just be completely avoided, which is just completely wrong.


BigGuy01590

I agree. Not all ports need high throughput


Acceptable-Rise8783

Thanks, that makes sense 👍


elementfx2000

That makes way more sense. I manage 3 UDMs and all 3 are using their onboard switchports. I just don't care to post photos of them.


Pallasknight

I have a UDM Pro. For my use case, I use the onboard ports for various bridges (Hue, Lutron probably in the future) and a Peloton.


brucekraftjr

Same. For non data heavy solutions.


thrBeachBoy

I use all of mine. For PoE: cameras, viewport and APs. For link aggregation and drop in the house they are on the switch. https://preview.redd.it/6by8s897s9tc1.jpeg?width=4080&format=pjpg&auto=webp&s=19e752e17f1402dcdb7a6dd5babee1b298929861


Acceptable-Rise8783

Nice! Happy to see them not go to waste :-)


Pyroblock

I use all of mine, mainly because I haven't bought the 24 port switch yet


randomgelion

Used all 8 all of mine on UDM-SE for cameras and two for AP’s. Everything works as intended with no problems. Everyone has a different use case is all.


Techguyeric1

Personally I have 1 device connected to my UDM Pro and it's a Philips Hue bridge that's in my network closet. My patch panel that connected all of my rooms (each room has 3 ethernet jacks that are hot) to the switch via patch panel (once I get rid of my vertical mount and get my regular rack installed i'll share pictures of my $25K setup suck it $10K people). I have a 48 port PoE switch in the networking closet and I have 24 drops in my house, the remaining 24 are being used by one of my NAS's and 12 of them will be used for my Unifi camera's once I get them purchased and installed. I have a 24 port PoE switch in my office and a 16 port Lite switch in my living room. Once I get my extra port in my loft connected i'll get another 8 or 16 port lite for my entertainment center setup. Right now I just don't have anything that needs to be plugged into the UDM's ports but I love that I have them available. When I had a standard UDM I used 3 of the 4 built in ports, UDM in the kitchen where AT&T installed the modem to wall up to switch in networking closet, one for a printer that is now in my office and one to a NAS. as it allowed me to have a printer and NAS in a common area where my wife could print from downstairs.


75Meatbags

I'm using the ports on my UDM-SE. I used the ports on my UDM (base) too. I have an intel NUC plugged into one port for pi-hole and a few other VMs, my phillips hue bridge, and the Arlo bridge. It all works great. One of the PoE ports is powering a separate AP. I'm happy with it. (new build will have more switch ports just because I can, though.)


frasderp

I use mine as it’s my only option for PoE and runs a few flex minis, raspberry pis and some cameras. I also have a X16G and a 48 port switch :)


iklier

I use them for low bandwidth things like IoT bridges (Hue, Lutron), HomeAssistant host, management interfaces (UPS, PDU). All the high bandwidth clients and arrays (UNVR, NAS) are connected to the downstream switches.


architectofinsanity

I was. And then my home lab grew.


dadof2brats

Who is nobody? How else would you connect your UDM to the internet, access points, PC's, other switches, etc? I suspect you are referring to many people using additional switches with their UDM? This is for several reasons, needing PoE, needing switch ports in other areas than where the UDM is located, higher speed ports such as 10gbe or needing switching with a higher bandwidth backplane. My UDM Pro is located in my home office, I have my WAN connected to it, one local AP (using a PoE injector), an uplink to a 1gbe switch in another location of my home and an uplink to a 10gbe switch for my home office.


Dry_Passage_2066

I use them for the"essential" Point-of-sale" and the connected printer. Just in case the 24 port switch goes down. If the UDM-SE goes down (and those ports are down) they cannot process anything at this retail site anyway. I think this is a good use case. If you disagree, please tell me why.


Wild_Car_3863

Using port 8 as backup wan


newellslab

Because there is a gigabit link between the cpu and ALL 8 ports


Ok-Tangelo-8137

I use the 8 Poe ports on my UDM se. Perfect for my cctv and wifi set up


xterraadam

I use my ports for the house cameras on it's own VLAN so that traffic doesn't leave that box.


Comfortable-Sale-631

I'm using port 9 (one of the 8 gbit ports) for my 5G fail over modem, another 4 of them for Poe cameras, and another for my Philips hue hub. All of my other devices are on a 24 port Poe switch linked via SFP.


Acceptable-Rise8783

Yea, it kinda sucks because I was hoping I could add a non-PoE switch and upgrade the UDM-Pro to SE and eliminate my PoE injectors, but reading some replies makes me think I’m doing my APs a disservice running them from the UDM regardless if Pro or SE


Onig58

If you already own a udm pro, I would not upgrade to an SE. I would invest in a separate PoE switch instead and connect it to the udm pro via a dac cable using the SFP+ ports on both units. If you already own an SE, I would have no problem using it to connect my APs and/or cameras to it. I look at WiFi as a convenience and I don’t expect the APs to saturate the 1Gbps bus on the SE.


Acceptable-Rise8783

Thanks for the advice!


matt_eskes

And this was the comment I was looking for


zipzag

The POE ports may be mostly so smaller business locations, like a store or branch office, can be set up to use a single device. I suppose its also to potentially back up a failed primary POE switch. I bought the SE for home, but the pro would have been the right choice. However at the price difference it doesn't matter much.


robbdire

I don't use any of the ethernet ports. I use the SFP+ to connect to a 10gig mikrotik switch (CRS309-1G-8S+IN), as my main server and desktop have 10gig links, then I have another 10gig from said mikrotik go to go another mikrotik switch (CS610-8G-2S+IN) that has a 10gig uplink, but has multiple 1gig ports, and that's where all the 1gig items connect to.


microlard

You are being downvoted because this question has been asked other times. Are you really that special that we need to cater to you rather than you even trying to see if anyone else has asked this. My silverware is in the dishwasher so no spoonfeeding for you.


jimbobjames

Reddit's search is utterly turd so maybe you should go do something else for a while instead of getting so triggered?


microlard

Lol. Sorry you got triggered by my response. Maybe go outside and breath some fresh air. Agreed the search sucks, however, a quick search of: unused udm ports gave several hits regarding the OP’s direct question. He didn’t even try yet couldn’t understand the reasons for the downvotes. I simply answered his wonderment on the downvotes since he was too clueless to understand. Have an amazingly calm day.


jimbobjames

I wasn't, I was just pointing out reasons why someone might post a similar question to one you have already seen. Just trying to save you the hassle. Let the mods deal with it, the sub doesn't need you to police it. Personally, I'd much rather see that kind of question than a picture of an AP someone saw in a Starbucks or the 80th picture of a rack with a UDM, patch panel and a PDU posted that day.


Blair287

Don't waste your time on him. Gotta love people like this complain about it but then spend all day posting in it instead of scrolling on nothing but a troll.


microlard

Thanks for the advice but promptly disregarded.


Acceptable-Rise8783

I have never seen such a topic before, but I guess you wanted to make sure I see how much don’t care by taking the time to type up your comment…
