HCSA-IP Network H19-301_V4.0 Full Course Free

The Huawei NetEngine AR651EW is a compact, all-in-one enterprise branch router that integrates:

LTE uplink

Wi-Fi 6 capability (802.11ax)

SD-WAN access

Security functions such as IPS and firewall

It is indeed Huawei's first edge router with built-in Wi-Fi 6 functionality, targeting small and medium-sized enterprise branches that require wireless access and SD-WAN features in a single device.

Huawei's six comprehensive border security protection capabilities for SD-WAN or converged gateway routers typically include:

Built-in Firewall – Provides basic packet filtering and security zoning.

Remote URL Filtering – Uses cloud-based services to filter harmful websites.

Antivirus – Detects and blocks malicious files.

IPS (Intrusion Prevention System) – Detects and blocks known threats and attack signatures.

Application-level ACL – Allows granular control of applications beyond Layer 4 (e.g., blocking TikTok, WhatsApp, etc.).

Data leakage prevention (DLP) and behavioral analytics may also be included depending on the security license.

However, "Data encryption" is a broader category not specifically named among the six security protection items in Huawei's SD-WAN documentation. Encryption (e.g., IPsec VPN) is used for secure tunnels but is not listed as one of the six application-layer protections.

Huawei defines thecore technical fields of campus networksas:

WLAN (Wireless LAN)

Wired LAN (Switching Network)

SD-WAN, when used forbranch interconnectionwithin enterprise campuses

WAN, on the other hand, is a broadercarrier-class infrastructureandnot specifically categorized as a campus network technology. It refers to long-distance, backbone, or ISP-level connectivity beyond the scope of typical enterprise campus deployments.

Huawei defines theWLAN network lifecycleusing acomprehensive four-stage model, which includes:

B. Plan: Network coverage, capacity, and performance planning

A. Construct: Deployment of APs, controllers, and configurations

C. Maintain: Ongoing network operation and fault handling

D. Optimize: Performance tuning, channel optimization, and roaming refinement

These stages are covered in theWLAN planning and deployment methodologyusing tools likeSCTandiMaster NCE-Campus.
