MikroTik CRS310-8G 2S IN: L3 Smart Switch Géré 2.5G Ethernet (100/1000/2500) Connexion Ethernet, supportant

Even as a Mikrotik advocate and fanboy I can honestly say that this is a good product. I'm using it as a Boundary router for the fibre connected Smarthome. It's not maxed out and we shift Terabytes of data around every week. Only complaint / comment is that there is a fan but it is noisy and sounds like it about to give up the ghost. But its important to get a Mikrotik with a fan especially if you use SFP+ ports. Dont be fooled the 10G ports run very hot. Mikrotik do a few passive 10G devices but I would not rate your chances.As usual RouterOS is great when it works and when it does not and you misconfigure something important like a firewall rule ... you did make a backup so you can reset and restore !!This product is a good way to get started with a 2.5G Router not just switch.

I was nervous about this system because so many people said it was difficult to get working. I have been in IT for a long time, but I never did networking as my full time job at least not officially. Add to that, it has been a while since I messed with a Cisco or Juniper or other. This switch was a cupcake to set up. I did some reading in advance and I knew which IP it would come up with. I downloaded and installed their Winbox package in Windows VM that I have for things like this. I plugged a USB to Ethernet dongle in and connected it straight to the Mikrotik port 1. It pinged on the default IP address immediately. I used the credentials listed in the small "manual" that came with the device and it logged in immediately. I do not remember needing to do anything special to get the various devices communicating other than connecting them to this new switch.The switch is running in my 80 degree F garage without an issue so far. The temps look good and the fan is running on low with 5 of the 8 ports filled and in use. I can only hear the fan when I get within a few feet of the device during normal operation.The switch does have a command line and I was easily able to SSH to it. The command line is different from any other networking device I have used, but seems to be well laid out. It has tab completion and you can simply type "/" followed by tabs to see a list of top level commands and sub-sections. The command line seems to logically follow the GUI, so you can learn what is where from checking out the GUI. I like the command line because I am often on a Linux or Mac system and can not easily run the GUI which seems to be Windows only.The 10G module is taking forever in shipping, so I am not able to test that yet but I will update this later. The 1G connections have tested out near theoretical maximums with iperf. I have not (yet) tested setting up VLANs, link aggregation, QOS or routing to see how much work any of that takes. As a standard switch without any advance set up, I think it will pass traffic out of the box. It had RSTP set by default so it should be safe to introduce to networks with more than one switch without worrying about introducing a loop, I tested intentionally introducing a (potential) loop and it did not cause an issue.At this point I think it is a great router/switch, but I am not sure I would recommend it for beginners.

Not sure if I did the setup correctly, but adding VLAN routing on the switch causes the CPU usage to increase heavily.As a L2 switch, it works amazingly, but you definitely didn't this much for an 8-port L2 switch

Tipica configurazione Mikrotik. Funzionale e silenzioso, nelle operazioni non pesanti, anche se con raffreddamento attivo. Consiglio l'acquisto di una Noctua NF-A4x20 PWM da 12V da andare a sostituire con la ventola di serie, non perché quella di serie sia cattiva, anzi è efficace ma rumorosa all'avvio dello switch o nelle situazioni di utilizzo intensivo anche se in realtà non è nulla di così fastidioso.Da qualche settimana è stato rilasciato anche il firmware per utilizzare SWos. NON è POE, se dovesse servirvi questa funzionalità.Una pecca è lo spazio tra le porte 2,5gbit dove degli rj45 con cappuccio potrebbero darsi fastidio l'un l'altro se ingombranti. Altra pecca è che, nel momento in cui scrivo la recensione, il prezzo di acquisto di amazon è troppo elevato. Siamo sull'indice dei 270 eura circa quando dai venditori terzi si trova anche a 210 con spedizione. Infatti uno lo ho acquistato da amazon e un altro da un venditore terzo (getic).Per tutto il resto a mio parere vale 5 stelle.Edit 29/07/2024: la ventola d'estate si sente un po' di più a causa delle temperature esterne elevate. Tuttavia con la Noctua per me è tranwuillamente sopportabile in quanto lo switch lo tengo in studio e ci sono anche le ventole del computer che comunque fanno rumore e quindi non ci faccio nemmeno caso. Sarà di fficile che lo tieniate nello stesso punto in cui dormite, pertanto lo consiglio sempre e comunque.

Device operates out of the box. I'm using it with 10Gb fiber backbone.Fan spinning is not loud in my configuration. Thou the installed Al ribbs could be larger. They even anticapated mounting holes.Im using it 1w and no objections. So far it does the job.

Doesn’t run silent and can get warm with SFP+ copper modules but RouterOS runs great as a switch on my 3 units.
