The VSC7434 E-StaX-III-68 stackable Enterprise Ethernet switch contains twenty-four 10/100/1000 Mbps Ethernet ports and four 10G XAUI ports. Two of the four XAUI ports can also be configured as two 12 Gigabit Ethernet (GE) stacking ports. VSC7434 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. The VSC7434 device contains a powerful 416 MHz CPU, enabling full management of both a standalone switch as well as a full stackable Ethernet switch solution. A comprehensive application programming interface (API) and software development package is available for Managed stackable Ethernet applications for faster time-to-market. The software API package integrates easily with third-party software, preserving existing software investments.
