Parameter select function
Scene introduction
H8922 4G Router provides parameter switching function to switch between working or temporarily stopped
links. For example, when the working L2TP link fails to work properly for some reason, it can switch to the
standby PPTP or IPSec link. The H8922 4G Routers switch multiple links according to the configured parameter
switching rules to ensure the reliability of network communication.
Configuration
In this scenario, you need to perform parameter select. For the configuration procedure, see Parameter select.
