To configure APN (Access Point Name) for cellular:
[Branch_Router] interface Cellular 0/0/0 [Branch_Router-Cellular0/0/0] apn-profile default [Branch_Router-Cellular0/0/0] dialer number *99# (or your carrier's code) [Branch_Router-Cellular0/0/0] modem auto-recovery [Branch_Router-Cellular0/0/0] quit Implement track-based static routes to fail over automatically. 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). huawei ar651 configuration guide
