In a typical campus hierarchy, a Layer 2 switch does not perform routing for user traffic. Therefore, its VLANIF interface is not used as a default gateway (Service IP). Instead, it is configured with a Management IP address to allow administrators or the iMaster NCE-Campus controller to access the device via SSH, SNMP, or NETCONF for configuration and O & M purposes.

iMaster NCE-CampusInsight provides full-stack visibility by analyzing three distinct layers:

User Layer (B): Focuses on user-specific issues like authentication failures or slow associations.

Network Layer (A): Monitors device health, packet loss, and latency across the physical/logical fabric.

Application Layer (D): Identifies over 6,000 applications and analyzes the quality of experience (QoE) for key apps like Zoom or Teams.

"Protocol layer" is not categorized as a standalone analysis layer in the official HCSP V2.0 framework; protocol issues are usually nested within the Network or User analysis categories.

Huawei's Xinghe Intelligent Campus defines three standard "Access Authentication" modes for users and terminals:

802.1X (B): High security, suitable for PCs and mobile devices with clients.

Portal (C): Common for guest access and public areas (web-based login).

MAC Address Authentication (A): Used primarily for "dumb" terminals like printers, cameras, and IoT devices that cannot perform 802.1X/Portal logins.

OSPF Authentication (D) is a protocol-level security feature used to secure routing updates between routers, not an access authentication method for end-user devices.

The Huawei Xinghe Intelligent Campus leverages SDN to deliver four core benefits:

Open Programmability (A): Via Northbound APIs for integration with 3rd-party apps.

Network Automation (B): Automating full-lifecycle O & M.

Rapid Service Provisioning (C): Reducing deployment time from weeks to minutes via templates.

Network Virtualization (D): Using VXLAN/EVPN to create multiple isolated logical networks (e.g., IoT, Office, Security) on a single physical infrastructure.

In a modern campus network, unified identity management is critical. iMaster NCE-Campus acts as a RADIUS and Portal server that integrates with existing enterprise directories. It supports synchronization and authentication against Microsoft Active Directory (AD) , LDAP , and third-party databases via standard protocols. This enables features like SSO (Single Sign-On) and ensures that user permissions are consistent with their existing corporate credentials.

In Huawei’s Xinghe Intelligent Campus solution, user access control is handled through three primary methods: 802.1X (B) for high-security enterprise environments, Portal (A) for flexible guest and web-based access, and MAC address authentication (C) for IoT devices like printers and IP cameras that lack a user interface. OSPF authentication (D) is a routing security feature used to verify the identity of neighboring routers, not an end-user access authentication method.

The iMaster NCE-Campus controller monitors the network via protocols like SNMP, NETCONF, and Telemetry to provide visibility into application traffic (A), topology (B), and link stats (D). However, original/raw NetStream flow information (C) is typically too voluminous for a management controller to process. Instead, these raw packets are sent to a dedicated Analyzer (like iMaster NCE-CampusInsight) which performs deep data mining. The controller only receives summarized reports or metadata from the analyzer.

The core philosophy of SD-WAN within the Huawei campus architecture is the decoupling of the Underlay (the physical transport network like MPLS, Internet, or 5G) from the Overlay (the virtualized service network). By using IPsec or VXLAN tunnels, SD-WAN creates a logical network where business policies—such as application-based routing and security rules—are applied. This allows enterprises to change their service logic without modifying the underlying physical WAN infrastructure.
