BDCOMS S3928 Switch

Layer 3 Gigbit SNMP Switch

BDCOM S3928 is a standard L3 congestion-less switch series, which are capable of multi-layer switching and wire-speed route forwarding.

Its high-performance ASIC and modular design enable users to employ a suitable number of interfaces and to configure scales of their networks with great flexibility, 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 S3928 is considered a very competitive Ethernet switching solution for community networking and workgroup networking in enterprise networks.

BDCOM S3928

Application
