NPM server requests promiscuous mode from the ESXi server

Table of contents

Updated July 18, 2017


This article describes why the NPM server is requesting promiscuous mode from the ESX server where it is hosted.


All NPM versions


Promiscuous mode is where NIC passes all received traffic to the CPU instead of passing only the frames that the CPU requested to receive. This mode is normally used for packet sniffing.

The QoE and NetPath services are part of the Orion software. When these services capture all traffic in NIC, Orion will request promiscuous mode from the NIC of the ESX server.
