I've had the MikroTik CRS310-8G+2S+in for several months now, running it in RouterOS, its been great. I've been using routerOS for several years now and I'am comfortable with it. I've got it going to three proxmox machines one of which is bonded with LACP using three 2.5G ports with Layer 3+4 hashing (The other two connected via the SFP+ ports), about 10 VLANS going through it all working great. I pretty much forget about having it most of the time until I go to check for updates. Makes migrating VM's around the machines when I do maintenance a breeze.
@@SB-qm5wg I also have been running a CRS310 for qutie a few months now. I have a small fleet of Proxmox servers made of HP EliteDesk 800 G3 mini machines with USB3 2.5Gbe NICs, which feed up to my CRS309 10GB switch by way of the SFP+ ports for my storage network. It's an absolute champ.
This is the perfect solution for an issue I've been having with my RJ45 to SFP+ adapters overheating. I'm ordering one right now! (currently a 20% coupon on it, too, making it $40 out the door with overnight delivery!)
@@GCTWorks the solution is that I won't be using SFP+ modules any longer. At one point I even tried mounting a fan to blow cool air on the modules, but it wasn't enough
@@Mikeeg0607 I'm just going to run the 2.5G ports. My current setup has multiple 1G ports and 4 10G SFP+ ports and I'm only using the SFP+ ports to connect my PC in one room to my server rack in another room. The PC only has a 2.5G RJ45 connection (currently connected via an ethernet cable and a SFP+ to RJ45 adapter that gets SUPER hot), so what I'm getting will be a more compact, more practical setup for me anyway.
Thanks! Was looking for a small switch like this to do testing. Went right over and bought one. Just a side note. It was under 50, BUT if you click the 20% off coupon as of when I leave this comment, you can buy this for under 40. well worth that. Thanks again!
I think it's a first time buyer enticement, I got one, fried it with a copper SFP, and did a return instead of exchange and didn't get the discount my second time.
i bought this exact switch (also from the STH video) in October (for referance 10 months ago) and it was worked great. - iperf3 shows 10Gbps and 2.5Gbps work perfectly. I use a DAC cable and a Fiber with with 10Gtek adapters and havn't had any issues at all. i have no ethernet DAC to confirm or deny what Tom said but i take face value as honest, and i do know sfp+ to ethernet adapters generally do get hotter than other adapters. Also stepping up to the Mikrotik switch Tom showed, is both an amazing switch, AND MUCH more expensive. Not a bad switch shown here, but can absolutly attest the Yuanley has been holding up great.
I bought the same Yuenley switch, and primarily use it in combination with a Raspberry Pi 3 as a tool to validate network connectivity and identify switch port connections. The Raspberry Pi is running the lldpd app, which supports both CDP and LLDP. So I plug the Raspberry Pi into one port of the Yuenley switch, and then I can use another port on the Yuenley switch to plug into a copper 10/100/1000/2500Mb/s connection or a 1/10Gb/s fiber connection (via SFP) and then issue the lldpcli command on the Raspberry Pi to see the switch and port that I am testing. This validates whether the cable to the switch under test is working, and that the cable was run to the correct switch port. It’s a pretty cheap and reliable solution.
Great! That was my first question. I don't need this switch do anything with the VLANs, however, the SFP+ ports on my main 10gb will be assigned specific VLANs. My use case is for a LAN party, just to be clear if I want this switch to ONLY be on the LAN Party VLAN as I don't want the party network to have access to my main network, that use case will work?
@@garydeluce464 If you have a managed switch, you can assign untagged trafic to a specific VLAN on a port and plug this switch in there, which means the traffic from all of its ports will end up on the VLAN you set on the managed switch.
What’s a funny moment. It’s been some months already I bought this same switch with the same strange brand and see it now on this channel is a surprise. So I bought this switch to connect my main Linux server and my Truenas server together with the 10gbs ports with some DAC and I can attest in my testing that my two computers talks at 1GB per seconds which is nice. Didn’t know about the thermal issue with SFP ethernet so I guess I will write on this switch to never plug those modules.
A couple months ago, I was shopping for a 2.5G PoE+ injector, they were all around $35-40. I saw a NICgiga 4x2.5G PoE+ / 2xSFP+ for $52 and got that instead. Seems to be working just fine, DAC backhaul to the main router and throughput is full 2.5 on the WAP using iperf3 over the wired connections...
I've had the max amount of officially allowed Mikrotik 10G for literally ears in their fanless CRS305-1G-4S+ (running SwOS as I did not need anything else) and they run pretty hot, like 90°C, sometimes above. You could warm tea with it. Yes, tested. But that is a passive but well-vented switch. This might hit 100+.
I bought one of the rebrand version for my self a few month back for $35. It works ok, i only uses it as a 2nd network to access my NAS(s) for video editing.
I'd like to see a decent priced 2.5G POE managed switch with a SPF+ port or even 10Gb POE. Netgear is lacking in this area, only having very expensive offerings.
Just a warning on these, I have the PoE version of the switch and tried the SFP to copper module for a while, it did fry the switch pretty quickly (it kept boot looping, even after I unplugged the SFP) had to send it back, but yes, using 10G fiber SFP and PoE 2.5 has been fine since (and on the old unit before I tried the copper).
Nice little box, and i agree about the microtek, just wish we had managed sub 100, I only need 2 sfp and 4 2.5. And fiber is fine for sfp, I don't mind buying the fiber for the link between NAS and the switch to avoid the heat. fiber is cheap
hi tom i have this in my home lab and the mikrotik as well. i also got a 2.5g 24 port switch which can do vlan but pricy. this device powers my 2 APs and its a good primary network for the family on my pfsense. the mikrotik i love but was taking more power and its kind of unused resource as i have more devices connected to my 24 port 2.5g switch.
My favorite place to stash unmanaged switches with no moving parts is the ceiling tiles for sure. No one expects there to be one between what should be home runs.
We've given up the fight against unmanaged switches. We just do NAC on the edge ports and use mac based vlans. That way at least stuff still ends up in their own VLAN even through a dummy switch like this one.
there is this MokerLink 12 Port 10Gbps SFP+ Managed Switch for 270 eur. what you have here in the video is nice for less than 50 eur but 12x10g SFP+ for 270 eur just blows my mind so much im actually scared to purchase
How secure is this compared to the Omada system switches? This product is cheap and functional, as are many others in the market. I have a similar one and it works great. However, If you'd like to recommend products based on their security reputation then keep up this opinion and I'll respect it. Cheap products are cheap and we get what we pay for.
I do use a couple of these for 1.5 year now (when they were still ~100€ for 8 ports). they have been working just fine whilst my TP-link much more expensive but further similar one broke down already. They are not managed but do pass Vlan information trough though to my Ubiquity access points though.
Interesting. You say between Unbiquity access points, plural. Do you think the switch would be able to pass the vlan info to end devices too? I have a UniFi gateway but all end devices are connected through switches like these because cost.
Dumb question: if you had a managed switch and say for example some ports you gave vlan 1 and others vlan 10. If you connected this (or another unmanaged switch) to the managed switch on a port that had vlan 10, would the other ports on the unmanaged switch be sudo vlan 10?
You said dac or fiber for the SFP modules in your video about 3:30 Do you have a link to the SFP modules that work good with this. I know when I 1st started it was a hit or miss what SFP modules work with switches. Thank you.
I have the MikroTik CRS310-8G+2S+IN. Of all of the the switches I've used, it's my least favorite. The web UI is awful, hardware offloading is a joke, the SFP+ ports don't work in SwOS, and it (at least mine) randomly stops responding to commands.
any idea what switch chip it is using (underneath that glued on heat sink, probably)? I wonder if programming pins (usually I2C or SPI) are accessible... Looks like it is a BGA, with a bunch of passives on the bottom of the board, so probably not. But maybe! (sometimes the programming pins are recommended to be pulled high or low to ensure the chip boots into its default operation, so if they did that with a resistor...)
i have two managed hassivo switches. also after watching STH. i run a backbone 10Gb on 10Gbt copper and the SFP+ module gets hot. working on changing it to fiber. Great devices though.
I got one of these cheap 2.5G switches, I kept getting a problem with the network connection dropping from my Mac. I think there was some anecdotal evidence on some forum or review site that you have to do something to MacOs, some setting to change. In the end I sent my unit back, because I couldn't deal with constant problems during my working day, I went back to 1G ethernet, and the problem stopped. Now I'm reluctant to take the cheap path into 2.5G, even though I've bought USB and PCIe adapters for a bunch of machines. If anyone knows about these MacOs problems, and what the solution may be, please post. I did the speed test, and got the right speed always, it's just my network would go down, and I'd need to power cycle the switch to get it back. Could have been a faulty unit I admit, the problem could happen after an hour or two of use.
Biggest issue I got with sone mikrotiks is the noise. My CRS310-8g+2s+in is even with noctua mod fairly loud. On SwOS it ramps up to 3000 rpm. I might throw in an pwm controller to tune it to a more pleasent 1500 rpm
Silly question, how do I get a cat6 cable to link up at 10gbit, which it theoretically can do? I've never seen that happen, it always links up as 1 gbit full duplex.
Mikrotik support is abysmal to non-existent. Bought and used a CRS309-1G-8S+ for exactly 370 days, at which point it would boot up and work for 1-15 seconds and then brick itself... no amount of reflashing, switching modes, etc... Mikrotik basically told me tough, the warranty was 1 year, so no tech support, go to public forums......
Personally, i think that its never a good idea to use these cheap Chinese branded devices in any network. You never know whats running on them and the may have potential security risks. Just my opinion.
think of it as renting a switch for $3.45 p/m for a year for connecting some backup storage together .... because after that probably die a quick and sudden death... and if it doesn't you got a rent free switch after that :)
to each their own, but I have zero interest in 2.5g ethernet. if this was a 5 port 10g-base-t switch with a couple of sfp+ ports, this would be a great desktop unmanaged switch. combined with the heatload problems you were talking about with the rj45 modules (which means a lack of internal cooling for the cage), I think i'd recommend skipping this one unless you REALLY need 2.5 for budgetary reasons instead of using 10g base-t or a proper 10g sfp+

That is cause it has a fake or changing MAC.
Because it's transparent to the network, unifi just picks the first device it sees running on that port.

Does it have 12-57 Volt input like Mikrotik? What's energy consumption?

I assume this means I could buy any dac cable which is compatible with my dell powerconnect 5524p and it should also work with this switch?
Any idea if these will pas vlan tags along (not strip them) even tho its unmanaged. Asking for a friend.
It passes them
Question, on a Dream Machine Pro, what’s the point of one 10 gig port when all the other ports are only 1 gig?
With a 10G feed multiple devices can pull 1G at the same time.
Silly question, how do I get a cat6 cable to link up at 10gbit, which it theoretically can do? I've never seen that happen, it always links up as 1 gbit full duplex.
Sticking with Gigabit Ethernet because it runs over Cat 5e

I've never needed a managed switch for any purpose. 🤷♂
This one is $60 and has basic management. No idea how well it works though…
Better managed alternatives for this price. Horaco or similar brands with a simple web interface.

think of it as renting a switch for $3.45 p/m for a year for connecting some backup storage together .... because after that probably die a quick and sudden death... and if it doesn't you got a rent free switch after that :)
