What are the advantages of Huawei CloudEngine S12700E switches?

The CloudEngine S12700E switches are flagship campus core switches in Huawei’s portfolio, detailed in HCSA-Sales-IP Network V6.0. They offer 4.8 Tbps per slot for high-speed forwarding (A), supporting Wi-Fi 6 deployments; a control and switching separation architecture (B) for flexibility and scalability; ultra-large buffers with HQoS (C) for quality of service in key applications; and redundancy design (E) achieving 99.999% reliability. However, support for low-rate legacy ports like E1, T1, and POS (D) is not a feature of the S12700E, as it focuses on modern high-speed interfaces rather than legacy connectivity. Thus, A, B, C, and E are the correct answers.References: HCSA-Sales-IP Network V6.0, CloudEngine S12700E Switch Features and Benefits.
