    Hi @Jdeaza ,

    Could you please provide the device model and current firmware version?

    Please also check if the SNMP service is enabled in "Security" > "Access Control" > "Service Access Control"

    Additionally, please ensure that LibreNMS and the Zyxel switch can ping each other, and that firewall rules allow UDP port 161 (polling) on the switch and UDP port 162 (traps) on LibreNMS.

    For reference on SNMP settings, please refer to the following guide:

    How to configure SNMP on a switch? — Zyxel Community

    If the issue persists after verifying the settings above, please provide more details regarding the monitoring failure (e.g., error messages when LibreNMS fails to poll the GS1920), along with relevant screenshots(important) or logs, so we can assist you further.
