For example, 3 would only collect every third packet. Then follow these steps: 1) go to the Network section and select Virtual Switches; 2) click “Add Standard Virtual Switch”; 3) then come up with a vSwitch name and other parameters as needed and click the Add button. VMware introduced Netflow for vDS in vSphere v5. As part of the Network Monitoring and Troubleshooting features, vSphere 5 provides NetFlow and Port Mirroring capabilities. One such good tool is ManageEngine NetFlow Analyzer which is available as free download for 30 day evaluation and can be downloaded fromÂ. Analyzing the Traffic. So after 15-30 minutes, Click on the sensor in the Netflow collector. vSwitch is the other term by which the standard switches are sometimes referred. Use the commands listed in this section to troubleshoot NetFlow problems. A vNetwork Standard Switch (vSwitch) is a virtual switch that can be configured on a single ESXi host. 4. And some of these features are unique to the Distributed switch only. Netflow was originally developed by Cisco and has become a de-facto industry standard for analysing network traffic. For example, 3 would only collect every third packet. Layer 2 Switch. Note: Netflow is only supported with vDS and not standard switches. Idle flow export timeout in seconds: Similar to the active flow timeout, but for flows that have entered an idle state. If you set the value to something other than 0, it will Each vSphere Standard Switch (VSS) contains both data and management planes, and the administrator configures and maintains each switch individually. NetFlow NetFlow is a networking protocol that collects IP traffic information as records and sends them to a collector such as CA The NetFlow standard does not require such and the only reason I can see that SolarWinds uses SNMP in this regard is to query the switch for the bandwidth of the interface. VMware 11,957 views. I'm exporting netflow from some of my VMware Distributed switches. Click OK to save the changes to the distributed port group. Since this is a vmware switch its bandwidth is not really a consideration. (This can also be accomplished by right-clicking the distributed port group and selecting Edit Settings). Think of this as the cleanup necessary to ensure that an idle flow gets shipped off to the collector in a timely fashion.

My 2960 and 4948 are L3 switches. Ensure you are running VMware vSphere 5.0 and have activated Enterprise Plus licensing to setup the vDS switch in your environment. NetFlow is an industry standard for network traffic monitoring. NetFlow-enabled routers export traffic statistics as NetFlow records which are then collected by a NetFlow collector. Now its time to configure Netflow on distributed switch level. Configuring  Netflow is a two step process i.e configuring Netflow collector and configuring Netflow on distributed switch. There are number of free open-source Netflow Collectors as well as commercially available ones as well. Using the data collected, network admins gain detailed insight into the types and amount of traffic flows across the network. So, with vSphere, there's two different types of virtual switches.
