Question of what happens between the host NIC and virtual switch than filtered traffic? Is likely filtered, RTP packets do not reach. RTP packets, which are needed for drainage), although the interface itself is not displayed.Ĭreate a virtual switch cling it on one VM after booting OSes traffic in sight, but he When checking the physical port Wireshark host OSes traffic seen (go One of which is included in the physical switch port (Cisco), to the port the traffic is merged with the other portsĬisco. There is a server with 2 physical interfaces on which is installed Windows Server 2012 Hyper-V in 2012. Mirroring traffic from the physical interface to the virtual switch Зеркалирование трафика Is there any way of doing that using the Hyper-V settings But what is needed, is to pass that mirrored traffic, coming from outside of Hyper-V to a guest virtual machine. The Hyper-V host machine port, and we even can monitor that traffic on the Hyper-V host. We can setup port mirroring on that switch (SPAN), so that all the traffic between A and B would be mirrored to There are machines A, B, and the Hyper-V host machine, all connected to the same physical switch, like HP Procurve or some Cisco device, etc. Victor, what you've posted is a description on how to monitor one VM's traffic on another VM inside the same Hyper-V, but what is needed, is to monitor traffic from some physical PCs on a VM, for example: But for TCP traffic, in a switched network, promiscuous mode isn’t going to help much.
The machine will always pick up broadcast traffic and promiscuous mode can help you pick up the multicast traffic.
Broadcast and multicast traffic will be sent out all ports. This prevents the machine from “seeing” all 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. Since the 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.
