Choosing a network switch should be a practical decision, not an overwhelming one. MikroTik’s CRS lineup covers a wide range of use cases, but most people do not need to compare every model to make the right choice.

In reality, CRS switches are usually selected based on where they sit in the network, how many high-speed ports are needed, and how much control you want. This guide walks through those basics and points you toward the right CRS series without overcomplicating the process.

What Is a MikroTik CRS Switch?

CRS stands for Cloud Router Switch. These switches are designed to handle traditional switching while also giving you the option to use more advanced network features when needed.

Most CRS models are designed to support both simple switching and more advanced network control, depending on how they are deployed.

The Three Questions That Matter Most

Before looking at specific models, answer these questions.

1. How many high-speed ports do you actually need?

Many networks only need a few 10G ports for uplinks, servers, or aggregation. Buying a switch with far more capacity than you will use adds cost without real benefit.

2. Where will the switch live in your network?

CRS switches are commonly used at the core, aggregation layer, access layer, or at the edge. Knowing the role matters more than raw specs.

3. Do you want simple switching or more control?

SwOS is a good fit for clean Layer 2 switching with minimal setup. RouterOS makes sense when you need VLAN routing, monitoring, or more advanced control.

CRS Switches by Deployment Type

Instead of focusing on individual SKUs, it is often easier to start with how the switch will be used.

High-Density Fiber and Aggregation

For networks that need multiple 10G or higher-speed uplinks in a single switch.

Commonly used series:

• CRS317 series
• CRS328 series

These models are often deployed at aggregation layers or for server connectivity where port density matters more than PoE.

PoE Access and Edge Switching

For powering cameras, access points, and edge devices while maintaining fiber uplinks.

Commonly used series:

• CRS354 series
• CRS328 PoE models

These are typically used in access-layer deployments where PoE is required.

Compact and Flexible Deployments

For edge locations, labs, or small racks where space, noise, and power efficiency matter.

Commonly used series:

• CRS310 series

These switches are often chosen when only a few high-speed ports are needed without overbuilding.

All-in-One Switching and Wireless

For environments that benefit from switching and wireless combined in a single device.

Commonly used series:

• CRS418 series

These are often used in smaller deployments where simplicity and footprint are priorities.

Core Switching and High Performance

For networks that need higher throughput and performance at the core.

Commonly used series:

• CRS812 series
• CRS804 series

These models are typically used where performance is more important than port count alone.

RouterOS vs SwOS

If you are deciding between RouterOS and SwOS, keep it simple.

Choose SwOS if you want:

• Straightforward Layer 2 switching
• Minimal configuration

Choose RouterOS if you need:

• VLAN routing
• Traffic control or monitoring
• More advanced network visibility

Many users start with SwOS and move to RouterOS later as requirements grow.

Avoid Overbuilding Your Network

One of the most common mistakes when selecting a switch is buying more ports or features than the network actually needs. CRS switches make it easier to scale intentionally by choosing the right model for each layer instead of forcing everything into a single device.

Final Thoughts

Choosing the right MikroTik CRS switch comes down to understanding where it fits in your network and what role it needs to play. Whether you are adding a few 10G uplinks at the edge or building out aggregation, there is a CRS series designed for that job.

If you are unsure which option makes the most sense, comparing CRS switches by deployment type is often the fastest way to narrow it down.
