Huawei CloudFabric solution has been awarded Gartner’s “Customer Choice” three times by March 2021. According to the Huawei CloudFabric Solution Wins Gartner Peer Insights Customers’ Choice for Third Consecutive Year article, Huawei CloudFabric solution received this honor in 2019, 2020, and 2021.

Huawei Wi-Fi 6 products implement 10 ms ultra-fast roaming for all terminals, not only Huawei terminals, by introducing a cache mechanism, ensuring that there is no frame freezing during roaming. According to the Huawei AirEngine Wi-Fi 6 Solution White Paper, Huawei Wi-Fi 6 products use a cache mechanism to store user information on APs and switches, which enables fast authentication and reconnection when users roam between APs. This mechanism is compatible with all terminals that support IEEE 802.11k/v/r standards.

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.

NE8000 M1A and F1A are not both 220 mm deep. According to the Huawei NetEngine 8000 M14 Routers Support Guide, NE8000 M1A is 220 mm deep, but NE8000 F1A is 400 mm deep.

 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.

CloudEngine 16808 is a high-performance core switch designed for data center networks and high-end campus networks . It supports up to eight SFUs (Switch Fabric Units), which are responsible for data switching and forwarding . The SFUs work in 1+1 backup mode, ensuring high reliability and availability .

The CloudEngine 16800 MPUD switch does not have a built-in intelligent processing chip. According to the CloudEngine 16800 Series Data Center Switches Datasheet, CloudEngine 16800 MPUD switch has a built-in management chip that provides management and control functions, but not intelligent processing functions. The intelligent processing chip is embedded in the CloudEngine 16800 AI chip card (AI-NPU), which provides AI-powered network analysis and O&M capabilities.

The leader AP does not establish a CAPWAP tunnel with the fit AP. The leader AP communicates with the fit AP through the management VLAN, and the fit AP establishes a CAPWAP tunnel with the AC. In tunnel forwarding mode, user traffic needs to pass through the leader AP. In direct forwarding mode, user traffic is directly transmitted from the AP egress rather than from the leader AP. In tunnel forwarding mode, the leader AP can manage more fit APs than in direct forwarding mode.

WPA3 is a new security protocol for wireless networks that provides enhanced security and privacy features compared to WPA2 . One of the advantages of WPA3 is that it eliminates the potential for dictionary attacks, which are a type of brute-force attack that tries to guess passwords by using a list of common words or phrases . WPA3 uses a more robust authentication mechanism called Simultaneous Authentication of Equals (SAE), which prevents offline password cracking attempts . The other statements are correct advantages of WPA3. WPA3 can encrypt data on open SSIDs using Opportunistic Wireless Encryption (OWE), which creates a unique encryption key for each user without requiring any credentials . WPA3 also meets the NSA/SuiteB security requirements of governments and banks, which specify the use of strong encryption algorithms such as AES-256 and Elliptic Curve Cryptography (ECC) . WPA3 also ensures that even if an attacker obtains the intermediate key during the handshake process, they cannot decrypt the data or derive the session key, thanks to a feature called forward secrecy .

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.

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.

CloudEngine S5732-H series multi-GE switches do not deliver a switching performance of 1760 Gbit/s. According to the CloudEngine S5732-H Series Multi-GE Switches Datasheet, CloudEngine S5732-H series multi-GE switches deliver a switching performance of up to 336 Gbit/s.

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 S12700E does not support PoE. PoE is a technology that allows network devices to receive power from data cables instead of power cables. PoE is usually used for access switches that connect to devices such as IP phones and wireless APs, but not for core switches such as CloudEngine S12700E. A single CloudEngine S12700E can manage up to 10K APs by integrating native WLAN AC capabilities4. A single CloudEngine S12700E can manage up to 50K terminals by using free mobility feature that ensuresconsistent user experience across wired and wireless networks4. CloudEngine S12700E integrates hardware-based OAM/BFD to provide fast fault detection and location for various services such as Ethernet, IP, MPLS, and VxLAN

The technology that is not recommended for data centers is 802.1x. This is because 802.1x is a port-based authentication protocol that requires each device to be authenticated before accessing the network. This can cause delays and complexity in data center environments where there are many devices and high-speed connections2

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.

The built-in LAN ports on all Huawei NetEngine AR6000/600 series routers can be used as WAN ports. According to the NetEngine AR6000 Series Enterprise Routers Product Overview, NetEngine AR6000/600 series routers support flexible WAN/LAN port configuration, which allows users to use any built-in LAN port as a WAN port.
