The hrp load balance device command presets the hot standby mode of the FW to the load balancing mode.
The undo hrp load balance device command presets the hot standby mode of the FW to the active/standby backup mode.
The FW supports two operating modes: active/standby backup and load balancing. The networking and configuration of the FW and upstream and downstream devices vary with the operating modes. There is no dedicated command to set a hot standby operating mode. Instead, it is determined by the VRRP configuration or configurations including hrp standby-device. To reduce the configuration difficulty, the web UI provides the configuration wizard for the hot standby operating mode. The corresponding command is the hrp load balance device. For example, if you want the hot-standby devices to work in load balancing mode, select the load balancing mode, and set other parameters according to the load balancing configuration example matching your networking.
This command is used only for configuration wizard on the web UI and is meaningless on the CLI. Therefore, you do not need to run it on the CLI.
