Q:
GLPI server cannot automatically discover router waiting devices

You probably missed these documentations:

• https://glpi-agent.readthedocs.io/en/latest/installation/index.html#linux-perl-installer
• And the caution notes here: https://glpi-agent.readthedocs.io/en/latest/configuration.html#server

You should know NetDiscovery & NetInventory task requires glpi-inventory-plugin, unless you want to use ToolBox.

Only inventory tasks are installed by default, during installation you have to use --type=network or --type=all

Finally, I used the deb method to install it.

Yes, I installed glpi-inventory-plugin,
After testing, it worked fine after adding --type=network

It seems that the official documentation does not explain the specific parameters and functions (or I did not see it)

Thinks
