The Ethernet switches are one of the products which Huawei engineers are most familiar with. The complicated models, various specifications and similar names often confuse people.
Huawei switches consist of the S1700, S2700, S3700, S5700, S6700, S7700, S9700 and S12700 series.
Today, let’s make a comparison the S12700 series.
Overview of S12700 Series Switches
The S12700 series uses a Huawei Ethernet Network Processor (ENP) and provides a native Wireless Access Controller (AC) to help build a wired and wireless converged network. Its Unified User Management capabilities deliver unified user and service management, and Huawei’s Packet Conservation Algorithm for Internet (iPCA) supports hop-by-hop monitoring of any service
flows, helping manage services in a more refined way. The S12700 series runs the Huawei Versatile Routing Platform (VRP), which provides high-performance L2/L3 switching services and rich network services, such as Multiprotocol Label Switching (MPLS) VPN, hardware IPv6, desktop cloud, and video conferencing. In addition, the S12700 series offers a variety of reliability technologies, including non-stop forwarding, Cluster Switch System Generation2 (CSS2), a switch fabric hardware clustering system that allows 1+N backup of Main Processing Units (MPUs), hardware Eth-OAM/BFD, and ring network protection. These technologies help improve productivity and maximize network operation time, reducing Total Cost of Ownership (TCO).
The last two figures in the names of Huawei modular switches represent the number of service slots. For example, “S12712” represents that this model has 12 service slots. The following pictures shows the Huawei S12700 series switches.
