A dialog will open where you can enter a name and a description. Click on the “Add…” button to create a new monitor session. Make sure that you do not right click on a port group or any other object in the inventory tree or you’ll not get to the right settings dialog:ĭon’t get distracted by all the tabs that offer other interesting settings and select the “Port Mirroring” tab:Īs you can see there is no port mirroring configured at the moment, since all details fields are empty. Now, edit the settings of the Distributed vSwitch. In this case the Server1 VM is at port 101, and the capture VM at port 102, as you can see in the next screen shot: The first thing we need to do is to write down the ports the VM we want to capture traffic of and the port of the capture VM are connected to. Either use promiscous mode or a monitor session, but not both at the same time! Important: do not enable promiscuous mode on the portgroup you are using the monitor session on or you’ll end up with duplicate frames. To do that we have to create a monitor session on the Distributed vSwitch by moving to the “Networking” view of the inventory. Let’s assume that we want to capture the traffic of Server1. This test dvSwitch is only used by one hypervisor, but that is enough for a capture test setup. So let’s take a look at an sample setup of a Distributed vSwitch running in a vSphere 5.0 environment, which isn’t the latest version – but I’ll get to a newer setup in a post in the future, because it gets much more complicated. NetFlow options, active LACP capabilities, private VLANs and – what helps with troubleshooting a lot: Port Mirroring. Also, VMware seems to always put the cool new stuff into the distributed vSwitches, so there are quite a few reason to use them if you can: they provide e.g. The main reason to use Distributed vSwitches is that you can create single logical vSwitch instances that span across multiple ESXi nodes instead of having to create identical vSwitches on each hypervisor.

Unfortunately, those special vSwitches require a Enterprise Plus license, so all installations that run on Enterprise or less do not get these and have to stick with standard vSwitches. While that works fine, some larger installations have an even better way of doing network captures of virtual machine traffic, provided by the so-called Distributed vSwitches.

In the first post I described how to capture packets in VMware vSphere environments when dealing with standard vSwitches.
