S12700 Series Agile Switches

Designed for next generation campus networks, Huawei S12700 Series agile core switches have a fully programmable architecture to best meet fast-changing service needs, allowing new services to be flexibly and quickly provisioned within six months.

The series provides high-performance Layer 2 and Layer 3 switching services, supports millions of hardware entries, and meets campus network evolution needs over the next ten years.

Built-in, large capacity Wireless Local Area Network (WLAN) Access Controller (AC) functionalities achieve wired and wireless convergence, eliminating the capacity bottleneck associated with ACs.

Full Programmability

A fully programmable architecture enables new services to be flexibly and quickly provisioned within six months.

Million-Level Hardware Entries

Supporting up to 1 million Media Access Control (MAC) entries, 3 million Forwarding Information Base (FIB) entries, and 1 million NetStream entries, the switches also provide: 8 x 100 GE and 16 x 40 GE high-density cards, fully adapting to terminal and service increases in Metropolitan Area Networks (MAN), higher education, and large enterprise scenarios.

Wired and Wireless Convergence

Support for native AC functionality, managing up to 10,240 Access Points (APs), with the wireless forwarding performance of a single device reaching 4 Tbit/s. Super Virtual Fabric (SVF) virtualizes core/aggregation plus access switches and wireless APs into a single device, greatly simplifying network management.
