To enable NetFlow data collection in NPM, which configuration is essential on the monitored devices?

• A. SNMP traps must be enabled
• B. NetFlow export must be enabled and directed to the Orion server
• C. WMI must be disabled
• D. SSH must be enabled

Answer: (B)

NetFlow data collection hinges on the device actively exporting flow records to a NetFlow collector. For NPM to receive those flows, the monitored device must have NetFlow export enabled and configured to send to the Orion server’s address (and port). Once NetFlow export is enabled and the destination is set to the Orion server, the device begins generating and sending flow data that NPM can ingest, interpret, and present in its NetFlow dashboards and reports. Without this configuration, no NetFlow data reaches NPM, regardless of other management settings. Other options don’t directly affect NetFlow data collection: SNMP traps are for event notifications, not flow data; WMI is a Windows management interface used for querying system information, not NetFlow export; SSH is a remote access protocol and not part of the NetFlow data path. Ensure the device is exporting NetFlow to the Orion server and that any necessary firewall rules permit that traffic.
