Product details

400G used to be synonymous with expensive, complex and unattainable. The CRS812 DDQ changes that. With a modern Marvell switch chip and a powerful ARM CPU, it offers advanced routing, switching and traffic management functions that millions of RouterOS implementations rely on - now with ports of up to 400 Gbps.

Where does it fit?

Top-of-rack/leaf switch with 400G uplinks to the spine
Campus core bridging of 10G legacy with modern 50G interfaces
Aggregation node for service providers
Labs, AI clusters, media workflows where fast "east-west" traffic is critical

The CRS812 scales your network from 10 to 400G in a simple yet managed RouterOS v7 box - without the need for extensive upgrades.

With the CRS812, 400 Gigabit is no longer out of reach - it's a way to take your network into the future while continuing to utilise your existing equipment.
