## Description

1U rackmount enclosure

Review: Der MikroTik CRS312-4C+8XG-RM ist ein richtig solides Arbeitstier. 8× 10GBase-T und 4× Combo-Ports bieten viel Flexibilität, gerade wenn Kupfer und SFP+ gemischt werden sollen. Verarbeitung ist top, Lüfter laufen leise und das Gerät passt sauber ins Rack. RouterOS bzw. SwitchOS bieten extrem viele Möglichkeiten. L3-Features, VLANs, LACP, Routing – alles da. Man sollte aber wissen, was man tut. Kein Plug-and-Play wie bei Consumer-Switches, sondern klar auf Admins und Homelab-Nutzer ausgelegt. Performance ist stabil, auch unter Dauerlast. Für Virtualisierung, Server, NAS oder Backbone im Heimnetz absolut geeignet. Pluspunkte: 10G auf Kupfer ohne Gefrickel Sehr flexibel konfigurierbar Gute Performance, stabile Firmware Preislich fair für die gebotene Leistung Minuspunkte: Einarbeitung nötig Webinterface nicht jedermanns Sache Fazit: Wer einen leistungsstarken 10G-Switch sucht und sich mit MikroTik auskennt (oder es lernen will), macht hier nichts falsch. Klare Empfehlung für Homelab und kleine bis mittlere Profi-Setups.
Review: I really needed a 8 ports 10gbe Switch, was looking at Netgear: easy set-up but too many quality trouble for the high pricing... Then I looked at Mikrotik, many ports , great reviews , but can I set it up? I went for Mikrotik and I don't regret. I am in Japan... My questions before purchase were answered instantly. The order was shipped from Latvia the day I ordered it and by Fedex!!! (shipping was only 40$). It arrived in no time, set-up by a real pro (Chris)that I founded on Fiverr, and finally a great switch at my office. Finally,the noise question: before setup I plugged it with my 10gbe NAS and 10gbe MacMini. Noise was very loud. After setup (and a firmware upgrade) the switch became very quiet.

## Features

- CRS312-4C+8XG-RM Mikrotik first product with 10G RJ45 Ethernet ports. It has 4 x 10G combo ports: use them for 10G RJ45 Ethernet or 10G SFP+, when you need an additional fiber connection
- Combo ports can be used alongside the 8 regular 10G RJ45 Ethernet ports at all times. These ports can also be software selected, so you can use RouterOS scripting, to decide which combo ports will be active
- CRS312-4C+8XG-RM switch is a practical solution for those who work with huge data files and need fast, capable connection 24/7: multimedia production, scientific research, game development, big data ysis and so on

## Questions & Answers

**Q: Is this a router and switch? Or just a switch.**
A: It is a layer 3 switch. A L3 switch is a switch with routing features, so his performance as a switch is equal or better than a layer 2 switch with similar features; the difference is in the routing performance: his performance is a bit lower than a pure router (with the same features). This is because the main motherboard hardware of the L3 switches is built to be a high performance switch. The main motherboard hardware of the routers is built to execute routing tasks, so a router is better than a L3 switch in these tasks. To compare their routing software performance, just see their software routing features (L3 protocols, etc). The performance of a router is mainly measured by his routing hardware capacity, not by his routing software features because the software features are added just buying/installing/enabling a software license and/or changing the NOS (Network Operating System). You can compare their routing hardware performance (between a L3 switch and a Router), looking for the packet throughput (measured in pps
 (packets per second)) and the total BW
 throughput (in Gbps
) in each brochure/datasheet
. The CRS312-4C+8XG-RM has a packet throughput of 178 Mpps
 (is called forwarding rate) and a BW
 throughput of 120 Gbps
. The switching performance is measured by the switching throughput also called switching capacity, 240 Gbps
 for the CRS312-4C+8XG-RM =>
 it is good as router and very good as high speed switch. L3 Switches are good "
cheap"
 solution for small enterprises or SOHO networks, because they replace the router and switch functions, all in one box. If you really need more performance, then you go for a separate real router and a high speed L2 or L3 switch.

**Q: Does this have the typical loud/jet engine fans in it?**
A: The fans do "ramp up" when passing packets and it is noticeable.

**Q: Is this a smart managed switch?**
A: Yes it is

**Q: Can this support vlans between 1 - 4094 like with cisco?**
A: Yes, and lots of info online how to do this. Configuration can be complicated and I've not sorted it yet - but this is my operational setup so have to be cautious. Watch YouTube, buy routers by example and be careful

Switch 10GbE de 8p de cobre+4 puertos combo cobre/sfp+. Todos los puertos de cobre soportan auto negociación 10G/5G/2.5G/1Gbps. Cuenta con 4 ventiladores lo que no lo hace apto para entornos domésticos donde el ruido puede ser un problema. Arranque dual ROS/SwOS, soporta todas las características avanzadas de un switch gestionable, VLAN, RSTP, access list, etc… Producto sólido y con un rendimiento increíble.
