BDCOM S3512GX is a standard L3 congestion-less switch, which provides up to 12 GE ports, and is capable of multi-layer switching and wire-speed forwarding. Its high-performance ASIC, and its modular design enable users to employ a flexible number of interfaces and to configure scales of their networks at ease, all based on their individual requirements. It supports plenty of access authentication models that can be flexibly configured, making it especially ideal for community access networks. Due to its high performance and low cost, BDCOM S3512GX is considered a very competitive Ethernet switching solution for community networking and workgroup networking in enterprise networks.
