NetFlow NetFlow is a networking protocol that collects IP traffic information as records and sends them to a collector such as CA NetQoS for traffic flow analysis. To send the NetFlow information to the vRealize Network Insight NetFlow collector, configure the physical device manually. You flow collector should support VMware netflow extension which contain VM-ID, vNIC-ID and Rule-ID. These IDs names can be acquired from VC and NSXM DB. Consequently, VMware has this to say in the ESX v3.5 documentation: “NetFlow on ESXServer embeds the virtual switch ID into the engineType and engineID fields of the header of each NetFlow export packet. YAF. Running through the Get-vDSWitch stuff, I can see how to query erspans already configured but I don't see a place where I can set the Collector IP & related settings. Note: For Cisco ASR/ISR (SD-WAN Assessment), If you have any existing data source in your environment, you need to add a separate collector. If you see a network device in your NetFlow Sources and you do not intend to collect NetFlow data from it, you can eliminate unnecessary traffic by turning off the export of data at the device. Configuring NetFlow in vSphere 6 – Virtual Reality Cheers, Supreet NetFlow Collector. If you are asking about the 'Switch IP Address', I don't think there would be any interruption. You may need to rename interface names so that you can remember what ports are mirrored, but after you have those things taken care of, you should see all the nice juicy IPFIX exports in your NetFlow collector and can begin running reports. Perhaps a better concern might be in the area of NetFlow performance analysis – how sending net flow traffic over the internal network will affect the already highly-congested corporate networks’ bandwidth limitations & constraints. A common value is UDP port 2055, but other values like 9555 or 9995, 9025, 9026 etc. (Flows from different virtual switches are always sent in separate packets.) You can also delete a collector, if necessary. Many, if not all of these software and tools above, have a Free version to use for either a limited amount of days/time or Sensors.
