The NE8000M1C supports dual AC/DC power modules. According to the NetEngine 8000 M1C Service Router Datasheet, NE8000M1C supports two power modules that can work in 1+1 redundancy mode. The power modules can be AC or DC power modules.

In the headquarters-branch VXLAN interconnection scenario, single-fabric networking is not supported. According to the Huawei CloudCampus Solution Description, headquarters-branch VXLAN interconnection is a scenario that connects multiple campus networks over a WAN using VXLAN tunnels. In this scenario, each campus network forms an independent fabric network with its own controller and gateway devices. Single-fabric networking is a scenario that connects multiple campus networks over a LAN usingVXLAN tunnels. In this scenario, all campus networks share the same fabric network with a unified controller and gateway devices.

The redundancy design of key components of the S12700E series switches can achieve 99.999% reliability. According to the CloudEngine S12700E Series Switches Datasheet, CloudEngine S12700E series switches support N+1 backup for MPUs, SFUs, CMUs, and power modules, as well as hot swapping for all components, ensuring high availability and reliability.

CloudEngine S1270OE-O8 provides eight LPU slots, four SFU slots, two MPU slots, two CMU slots, and six power module slots1.

The CloudEngine 16800 series switches do not support 4, 8, 12, and 16 LPU slots. According to the CloudEngine 16800 Series Data Center Switches Datasheet, CloudEngine 16800 series switches support three models: CE16804 (4 LPU slots), CE16808 (8 LPU slots), and CE16816 (16 LPU slots). There is no model that supports 12 LPU slots.

 Policy association achieves policy flexibility and network simplicity on large campus networks. With policy association, user access policies are centrally managed on the gateway devices and enforced by gateway and access devices. According to the Huawei CloudCampus Solution Description, policy association is a feature that allows user policies to be associated with user groups, service types, or service priorities, rather than IP addresses or VLANs. Policy association simplifies network configuration and management, and improves user experience.

HQoS (Hierarchical Quality of Service) is a technology that provides hierarchical per-user-per-service scheduling and quality guarantee for VIP users and high-priority services. HQoS can implement fine-grained traffic control and service differentiation based on user groups, service types, and service priorities. The control device and access device are not virtualized into one device by HQoS.

NE8000 F1A has 36 1GE ports. According to the NetEngine 8000 F1A Service Router Datasheet3, NE8000 F1A supports flexible combinations of up to 56 ports, including 36 x GE, 16 x 10GE, 2 x 40GE, and 2 x 100GE ports.

 CloudEngine S7700 switches support service port clustering and CSS2 switch fabric clustering. According to the CloudEngine S7700 Series Switches Datasheet, service port clustering enables multiple physical ports to form a logical port that provides higher bandwidth and link redundancy, while CSS2 switch fabric clustering enables multiple switches to form a logical switch that provides higher performance and simplified management.

AirEngine 6760R-51E is a Wi-Fi 6 AP designed for rail transit scenarios. It supports 8x8 MU-MIMO and eight spatial streams, achieving a rate of up to 5.95 Gbit/s2. AirEngine 6761-21T is a Wi-Fi 6 AP designed for indoor scenarios such as offices and classrooms. AirEngine 6760-X1E is a Wi-Fi 6 AP designed for indoor scenarios such as hotels and shopping malls. AirEngine 6760-51EI is a Wi-Fi 6 AP designed for indoor scenarios such as stadiums and exhibition halls.

M-LAG can be deployed on server leaf nodes in NOF+ scenarios. According to the Huawei CloudFabric Data Center Network Solution White Paper, NOF+ (Network-Oriented Fabric+) is a data center network architecture that supports both Layer 2 and Layer 3 connectivity between servers and leaf nodes. M-LAG (Multi-Chassis Link Aggregation Group) is a technology that enables multiple leaf nodes to form a logical device that provides high availability, load balancing, and simplified management.

Each AP does not need to be designed to cover as large an area as possible in order to provide better coverage in a high-density scenario. According to the Huawei AirEngine Wi-Fi 6 Solution White Paper, in a high-density scenario, each AP should be designed to cover a small area with high signal strength and low interference, which can improve user experience and network capacity.

iFIT is a technology that can provide real-time service quality visualization and minutes-level fault demarcation. It can collect and analyze network traffic data, identify network problems, and optimize network performance. iFIT uses Telemetry to collect data from network devices, and uses Network Cloud Engine (NCE) to process and display the data. iFIT can also use In-band Network Telemetry (INT) to embed data into packets for more accurate measurement.
