This document describes the usage of wildcard tunnels for VMware vCenter monitoring. The current implementation of VMware vCenter creates one tunnel interface from every ESXi host to DMF.

DMF-8.4.0 DMF Wildcard Tunnels VM Monitoring vCenter

The Wildcard tunneling feature allows the DANZ Monitoring Fabric (DMF) to decapsulate L2GRE-based tunneled traffic from any remote source. This feature, supported on SwitchLightOS (SWL) based DMF switches in prior releases, now allows wildcard tunnels on Arista EOS-based DMF switches. Please refer to the DMF User Guide for more information on configuring the feature.
