failed to set hardware filter to promiscuous mode wireshark

This prevents the machine from “seeing”Īll of the network traffic crossing the switch, even in promiscuous mode, because the traffic is never sent to that switch port if it is not the destination of the unicast traffic. The virtual switch acts as a normal switch in which each port is its own collision domain. Virtual network is connected to a virtual switch, the traffic is directed at the switch to the port that has the destination. However, it doesn’t really matter because the primary benefit of promiscuous mode is to capture traffic not destined for the computer. But there is an OID for doing it programmatically. If that does not work, remove the line from the global settings node and add it back under the node for the appropriate ethernet card that you would like to attempt to use this setting on.Īgain, I do not know if this is a supported config item in Hyper-V, definitely let me know if it works. The first place I would suggest is under the node. In Virtual Server 2005 R2 SP1, you could manually add a line to the configuration file that would allow this. I do not know if this feature is supported on Hyper-V yet or not, but here is something you might be able to try. As a result, your VM is only seeing broadcast traffic, and traffic which is bound for it.

This enhances security in a virtual environment.

The virtual switches on Hyper-V act like they have per-port switching, hence you wont see all of the traffic accross the system.
