To configure APN (Access Point Name) for cellular:

A primary default route via Ethernet (preference 60) and a backup via Cellular (preference 100) ensures zero-touch redundancy. The AR651 provides multiple Layer 2 Gigabit ports. For security, segment traffic into VLANs (e.g., VLAN 10 for Data, VLAN 20 for Voice, VLAN 99 for Management).

Introduction In the modern enterprise network, the boundary between the local LAN and the wide area network (WAN) is no longer a simple threshold. It is a dynamic space requiring routing, security, and deep packet inspection. Huawei’s AR651 enterprise router, part of the Agile Series, is designed to occupy this critical space. As a converged access device, the AR651 supports 3G/4G LTE, Ethernet WAN, and VPN acceleration, making it a staple for branch offices and Industrial Internet of Things (IIoT) deployments. This essay provides a structured technical guide to configuring the AR651, moving from initial access to advanced security policies, using Huawei’s proprietary Versatile Routing Platform (VRP). Phase 1: Initial Access and Basic Hardening Before any data flows, the administrator must establish a console connection. The AR651 defaults to a baud rate of 9600. Using a terminal emulator (e.g., PuTTY or SecureCRT), the user enters the initial AAA authentication framework. huawei ar651 configuration guide

The AR651 excels at hybrid WAN. Typically, you configure an Ethernet WAN (e.g., GE0/0/0) and a 4G LTE backup (Cellular 0/0/0). The AR651 provides multiple Layer 2 Gigabit ports
