Free mobility is supported on a hybrid network consisting of Huawei and third-party devices, and the authentication point can be deployed on third-party devices. According to the Huawei CloudCampus Solution Description, free mobility is a feature that allows users to access network resources without changing their IP addresses or VLANs when they move within a virtual network (VN). Free mobility can be implemented on a hybrid network by using VXLAN tunneling technology and policy association.

The free mobility function allows users to obtain the consistent network access policy regardless of their location and IP address, but it does not require the network to be made up entirely of Huawei devices. According to the Huawei CloudCampus Solution Description, free mobility is supported on a hybrid network consisting of Huawei and third-party devices, and the authentication point can be deployed on third-party devices.

BGP EVPN is a control plane protocol that can be used for VXLAN networks . VXLAN is a technology that creates overlay networks to extend Layer 2 connectivity across Layer 3 networks . BGP EVPN has the following functions as a VXLAN control plane protocol:

It automatically establishes the VXLAN tunnel between VTEPs (VXLAN Tunnel Endpoints), which are devices that encapsulate and decapsulate VXLAN packets . You do not need to manually configure a full-mesh tunnel between all VTEPs, which reduces the configuration complexity and improves the scalability .

It advertises host routes and MAC address entries on the control plane, which are used to learn the location of hosts and their corresponding VTEPs . This reduces the unknown traffic flooding that occurs when the destination MAC address is unknown, and optimizes the packet forwarding by using optimal paths .

It implements Layer 2 interconnection between data centers in different networking modes, such as bridging, routing, or integrated routing and bridging (IRB) . This enables seamless communication between hosts in different subnets or VLANs across data centers .

It advertises subnet routes to implement Layer 3 interconnection of data centers through VXLAN tunnels . This enables routing between different subnets or VLANs across data centers without requiring an external gateway device .

SDR (Software Defined Radio) is a technology that can be used to switch the number of RFs (Radio Frequencies) dynamically. According to the Huawei AirEngine Wi-Fi 6 Solution White Paper, SDR enables an AP to dynamically switch between 2.4 GHz and 5 GHz bands based on the number of users and service requirements, improving spectrum utilization and user experience.

 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.

iMaster NCE-FabricInsight is Huawei’s intelligent O&M software that can provide network-wide visibility, intelligent analysis, and automated O&M for data center networks. iMaster NCE-FabricInsight can collect data from various sources, such as SNMP, Telemetry, Syslog, sFlow, and iFIT. It can also use AI algorithms to detect anomalies, locate faults, predict risks, and optimize performance. iMaster NCE-FabricInsight can also automate network configuration, deployment, verification, and recovery.

CE6820 does not support 100GE uplink ports. According to the CloudEngine S6800 Series Switches Datasheet, CE6820 supports 48 x 10GE ports and 4 x 40GE ports, but not 100GE ports.

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.

Spine nodes are core nodes on the fabric network, but they do need to support VXLAN in some scenarios. According to the Data Center Networking: What It Is, Why It Matters, And Types article, VXLAN is a tunnel encapsulation technology that allows overlay networks to be created on top of the underlay network. Spine nodes need to support VXLAN when they act as gateways between different overlay networks or between overlay and underlay networks.

The WAN-side controller can manage only WAN services, not LAN services. The LAN-side controller can manage both LAN and WAN services. This is because the LAN-side controller supports both SD-WAN and SD-Campus functions, while the WAN-side controller only supports SD-WAN functions.

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.

The iMaster NCE-Fabric cannot be deployed in a single-node system. According to the iMaster NCE-Fabric Product Overview, iMaster NCE-Fabric is a distributed system that consists of three nodes: the management node, the control node, and the analysis node. The management node provides basic management functions, such as configuration, monitoring, and alarm management. The control node provides control functions, such as VXLAN tunnel establishment and policy association. The analysis node provides analysis functions, such as network health analysis, fault diagnosis, and performance optimization.

 NE8000 X4 and X8 are high-end core routers designed for large-scale IP backbone networks, data centers, and metro networks . They support various redundancy designs to ensure high availability and reliability, such as MPU (Main Processing Unit) 1+1 backup, SFU (Switch Fabric Unit) 7+1 backup, and PEM (Power Entry Module) 1+1 backup . MPU 1+1 backup means that two MPUs work in active/standbymode and provide control plane redundancy . SFU 7+1 backup means that eight SFUs work in N+1 mode and provide data plane redundancy . PEM 1+1 backup means that two PEMs work in active/standby mode and provide power supply redundancy . The NE8000 X4 and X8 do not support power supply 9+1 backup, which is a feature of the NE8000 X16 router .

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.
