Summary

The Cloud Router Switch series are highly integrated switches with high performance ARM CPU and feature-rich packet processor. The CRS switches can be designed into various Ethernet applications including unmanaged switch, Layer 2 managed switch, carrier switch and wired unified packet processing.

Warning: This article applies to CRS3xx series switches and not to CRS1xx/CRS2xx series switches.
