MikroTik CRS812-8DS-2DQ-2DDQ-RM – 400G Cloud Router Switch
The MikroTik CRS812-8DS-2DQ-2DDQ-RM (CRS812 DDQ) is a high-density 400G Cloud Router Switch built for data centers, ISP core networks, enterprise backbones, and high-performance aggregation environments.
Designed for modern spine-leaf architectures and high east-west traffic, this multi-speed switch supports 50G, 200G, and 400G connectivity, enabling scalable and future-ready network deployments. Whether used as a core aggregation switch or a data center spine device, the CRS812 DDQ delivers high throughput with flexible port configurations.
Powered by RouterOS v7, it provides advanced Layer 2 and Layer 3 features including VLANs, static and dynamic routing, traffic engineering, MPLS, and full traffic control capabilities.
Ports Configuration
- 2 × 400G QSFP56-DD ports
- 2 × 200G QSFP56 ports
- 8 × 50G SFP56 ports
- 2 × 10G Ethernet (RJ45) management ports
The QSFP56 and QSFP56-DD interfaces support breakout modes, allowing deployment of 50G, 25G, and 10G connections depending on transceivers and cables. This makes the CRS812-8DS-2DQ-2DDQ-RM ideal for mixed-speed and migration-ready network environments.
