The MikroTik CRS (Cloud Router Switch) series comprises network devices that combine the functions of a traditional layer 2 switch with the capabilities of a layer 3 router. They stand out from other similar devices due to their ability to handle both port switching and data routing functions.
In comparison to standard switches, CRS devices are more advanced, offering additional features typical of routers. They can manage network traffic, filter IP addresses, and handle routing functions between subnets. Additionally, they can support VLANs, allowing the segmentation of the physical network into logical segments.
The key difference between CRS and traditional switches is their ability to perform routing functions. This capability allows them to act as central management devices for larger-scale networks where both switching and routing functions are required. In the case of other switches, routing functions are typically limited or entirely absent.
MikroTik CRS devices, besides standard port switching functions, also offer the ability to manage optical links, support Power over Ethernet (PoE), or even include built-in Wi-Fi access points, making them versatile solutions for various networking needs.
Diverse Applications and Functions of CRS
MikroTik CRS devices are layer 2 and layer 3 switches with built-in routing capabilities. Here are a few models from the CRS series and their typical applications:
