Reboot the 4G modem of MSR810-LMS-EA every 30s, reboot the device after 5 reboots

Network Topology

A 4G SIM card is inserted into the device, and the user accesses the 4G network through DDR dial-up.


Problem Description

Customer requirements: The device performs network connectivity detection every 15 minutes. If it detects that the network is unreachable, it reboots the modem for a total of 5 times. If there is a successful detection in the middle, the detection failure count is reset. If the network is still unreachable after rebooting the modem 5 times, reboot the router.


Process Analysis

After analysis, we can use EAA combined with NQA detection to reboot the modem and device.

Solution
