The VSC7431 E-StaX-III-28 Enterprise Ethernet switch contains twenty-four 10/100/1000 Mbps Ethernet ports and two 12G interconnect ports that can be configured to provide 28 ports (24× 1G and 4× 1G). Two VSC7431 devices can support up to a fifty-six 10/100/1000 Mbps configuration using the 2 × 12G interconnect ports. VSC7431 provides a rich set of Enterprise Ethernet switching features. Using multistage Versatile Content Aware Processing (VCAP), it delivers VLAN and QoS processing, enabling the delivery of differentiated services, security through intelligent frame processing, and egress frame manipulation. A powerful 416 MHz CPU in the VSC7431 device enables full management of a standalone switch without the need for an external CPU. A comprehensive application programming interface (API) and software development package is available for managed Ethernet applications for faster time-to-market. The software API package integrates easily with third-party software, preserving existing software investments.
