Highlights
• Supports 12G stacking with less than
100ms failover
• Management of 800 switch ports from a
single IP address
• Lowest latency architecture
• New shared buffer memory architecture
Applications
• Stackable Smart switch
• Fully managed L2/L3 switch
• Fully managed Stackable switch
Microsemi’s next-generation switch family delivers a comprehensive
end-to-end Enterprise Ethernet solution.
The VSC7432 E-StaX-III-48 stackable Enterprise Ethernet switch
contains twenty-four 10/100/1000 Mbps Ethernet ports and two 10G
XAUI ports. The XAUI ports can also be confi gured as two 12 Gbps
stacking ports.
VSC7432 provides a rich set of Enterprise Ethernet switching features.
Using multistage Versatile TCAM technology (VCAP), it delivers VLAN
and QoS processing, enabling the delivery of differentiated services,
security through intelligent frame processing, and egress frame
manipulation.
The VSC7432 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.
