Device Layer uses SNMP polling by ThousandEyes Enterprise Agents installed on your network to automatically discover network devices. Provide some basic configuration, and Device Layer will automatically find and monitor whatever SNMPv2c- or SNMPv3-capable device you want--routers, switches, firewalls, load balancers, wireless access points, and more! The data from Device Layer is provided to the Device Layer view, and is added to the Path Visualization view on any test with a Path Visualization that's run from an Enterprise Agent configured for Device Layer monitoring. Switch from the Path Visualization view to Device Layer view with a single click on a device.
