## Description

CRS309-1G-8S+IN

Review: Prestazionale e di buona fattura - Come da oggetto, ho trovato l'apparecchio prestazionale e di buona fattura. Non ho a disposizione misurazioni effettive delle velocità di trasferimento dati, ma è silenzioso (il che non è poco) ed, al momento, affidabile
Review: Sehr gute Preis/Leistung - Verwende den Switch Zuhause in meinem lokalen 10-Gigabit Netzwerk. Der Switch funktioniert nach der Einrichtung von SwOS perfekt, allerdings kann die Einrichtung für Anfänger etwas knifflig sein, was aber bei Netzwerk-Equipment logisch ist. Die Preis-Leistung ist grandios und es gibt kaum etwas vergleichbares auf dem Markt. Mein Plan war mein lokales Netzwerk etwas zu verbessern, da wir im Sommer einen 2,5 Gigabit Anschluss bekommen. Mit diesem Switch war das sehr günstig möglich und das Produkt wirkt auch sehr wertig und ist sein Geld mehr als Wert. Die Kompatibilität ist auch sehr gut. Für die LAN Ports verwende ich die Herstellereigenen SFP+ Module (Mikrotik S+RJ10, MikroTik S-RJ01) die ohne Probleme funktionieren. Module anderer Hersteller (10Gtek AXS85-192-M3) funktionieren bei mir auch ohne Probleme und es werden sogar die erweiterten Infos angezeigt (Temperatur, Spannung, Signalstärke, Rauschen usw...). Kann mir nichts besseres vorstellen und werde wahrscheinlich zukünftig auch weiter auf MikroTik SFP+ Switches setzen.

## 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.

### ⭐⭐⭐⭐⭐ YES, It Works!! 10g mixed media and affordable. Now with MORE Security.
*by A***R on 11 October 2025*

I was adding 10g to my home network, yes I like playing with tech. I needed both fiber and copper. This switch gives the flexibility to have your cake and eat it. Just plug in the SFP+ interfaces you need. I needed three fiber and a couple of copper 10g connections. I get amazing speed with this switch. I use 10g on the computer and 10g (fiber) on my NAS and I get blazing speed. SFP interface are inexpensive and you don't have to use Mirkotik SFP interfaces. I did change the unit from RouterOS to SwitchOS, this is just an option in the web interface and makes the unit easier to use as a switch. UPDATE 01-13-2026 The hardware quality is still amazing with these switches, HOWEVER, be warned that the RouterOS has had a security update. New units ship with a new version of RouterOS that has Severe security. Simple changes, such as changing the switch from running RouterOS to SwitchOS now requires juggling three balls, while doing a tap dance, and singing the Catalina Magdalena Lupensteiner Wallabeiner song. But it's not quite that easy. You have to open a terminal window and do a command line mode change and power cycle the unit (or use the reset Switch, a soft restart will NOT work) within a short time limit, then make the change in the interface and apply, hoping you get it right. Any documentation shipped with the router about this? NO. Any warning in the Interface? NO, just a cryptic error message that the unit can't do the change. I had to look it up on the internet. So when you are first setting up the unit you have to be Next to it, You can't install it then set it up. Fun Times... I understand the need for security, but making a change like this and not including a small slip of paper or a sticker that says "WARNING the software on this unit now had Security changes and you'll have to enable the ability to make changes" would be nice. ALSO being plugged into the Management port on the Switch doesn't make a difference. So why is it called a Management port then? You can't manage the firmware any differently than any other port. Still love the unit though. I have purchased 3 of the 8 port and 3 of the 5 port units and I will continue to purchase more as needed.
