## Questions & Answers

**Q: Will the 10g sfp+ ports support 1g/gige sfp's (i.e. are the ports 1g and/or 10g capable)?**
A: If you try to use a 1Gbit SFP transceiver that isn’t from MikroTik you will likely at first have problems and it might not work.  If this happens you have to go into RouterOS and turn off auto negotiate for that port.  You want to manually select the speed as well.  Then I’d recommend that you use masking tape or a label maker to mark the physical router so that you or a future user knows that one of the ports has auto negotiate turned off.  

You’ll actually need to do this with the MikroTik S+RJ10 as well as it has problems sticking too the highest speed your cable can handle (it’s a multi speed 1G/2.5G/5G/10G transceiver)

I don’t know if SwitchOS has the same problems.

**Q: Do these switches have the ability for mlag? i.e. i want to have two of these as core switches for redundancy.**
A: I don't believe so. You would need to check with MikroTik to see if that feature is available in the Router OS.

**Q: Has anyone tried to put two ports in lacp 802.3ad in active mode?**
A: Yes, no problems.

**Q: Will cisco sfp-10g-sr and sfp-10g-lrm sfp's work in this?**
A: Cisco compatibles have worked well for me.  This is not nearly as finicky as a Cisco switch.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Review for MikroTik CRS309-1G-8S+in
*by R***B on June 29, 2025*

The order arrived quick and I received everything as expected. I am a big Fan of MikroTik. As an Network Engineer I work with a lot of brands HP, Cisco, Fortinet and the list goes on I thought for my own network I would try MikroTik and I was impressed. What you get for the price is unbeatable and their products are solid with a robust set a features. The switch runs quiet and is powered by POE and that doesn't diminish its performance. This switch is connecting a 3 PVE cluster and a bare bone TrueNAS server and I got a full 10 gig network through my house and lab. I will be adding a few more of their switches in the near future. I would stay with RouterOS because while their switchOS has a clean layout and is very simple not offering all of the features the other OS it doesn't offer https at least that I am aware as I write this so creds to login is sent in the clear as soon as they add that I would be game if I didn't need all the other features offered in RouterOS.

### ⭐⭐⭐⭐⭐ Fast switch, with a bit of a learning curve
*by E***0 on October 11, 2024*

I'm redoing my homelab and saw this little gem. For the price, it's not bad. 8 SFP+ port, all 10G. Perfect for my servers and my computer. It also performs much better than some enterprise equipment. For the first time, I see my servers reaching 5GB, peak, transfer rate. It probably could do better in SwOS.Very low power. This is replacing my existing brocade switch and compliments my CSS326 switch. I did notice a 20% decrease on my UPS load.It does come with rack ears which is nice, but they are a bit flimsy.Now it's "dual boot." Currently running RouterOS. It's great piece of OS. Lots of options. But if you want a simple, easy to use GUI, switch it over to SwOS. Please update the OS once you do. I think there is a fix for DHCP. I switched it over to DHCP, pre update, and rebooted the switch. It didn't pick up an IP address. Switch still function and passing traffic, but I couldn't log into the switch. I had to order console cable and reset the config.It's a powerful piece of equipment and I see it fitting nicely in my environment. Plus, it's the best bang for bucks. You get a prosumer device at a consumer value.

### ⭐⭐⭐⭐ Noisy PoE?
*by A***N on September 11, 2023*

router seems to work pretty well sans one issue: it is VERY noisy if you use PoE power. idk what's up with that but man it is ear splitting, headache inducing bad. works just fine from the included power brick tho, only poe power is noisy. my initial plan was to just power this thing from a neighboring CSS610 and nothing else but with how noisy it is idk if i'm gonna be able to do that by my desk on an open rack lol, maybe in an enclosed cabinet. maybe the one i got is just kinda bunk lol, bad capacitor somewhere or smth like that. maybe don't do what i did and buy from a not authorized mikrotik reseller (there's a couple on amazon that are lol, look for them)unrelated to that, it boots up in RouterOS mode so it needs a wee bit of looking at the config and updating to v7 before it's truly ready to go, or bumping into SwOS if you don't need/want a router-switch and want it to justwerk. RouterOS has nice features tho and router-switches aren't super difficult to set up.
