Description: Manages NetFlow cache configuration and export settings, providing traffic flow statistics organized by protocol and port.
IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring CISCO-NETFLOW-MIB with a free 30-day trial of IPNetwork Monitor.
What Is CISCO-NETFLOW-MIB?
CISCO-NETFLOW-MIB provides SNMP access to NetFlow cache configuration, export settings, and traffic-flow statistics on Cisco routers and switches, letting smaller organizations use NetFlow traffic accounting without a full flow-collector infrastructure. It exposes categories of data including per-interface NetFlow enablement, cache type/configuration, active and inactive flow counts, and flow timeout settings, alongside export configuration and statistics. From a monitoring standpoint it is primarily a traffic/performance-visibility MIB rather than a hardware-health one — cnfCIActiveFlows, cnfCIInactiveFlows, and cnfCICacheEntries reveal whether the flow cache is healthy or nearing capacity (which can affect flow-accounting accuracy), and cnfCINetflowEnable/cnfCIMcastNetflowEnable confirm the feature is actually turned on where expected. It relies on the underlying NetFlow export protocol and typically complements interface (ifTable) and export-destination configuration to fully characterize traffic flows. It is commonly deployed on Cisco routers/switches used for traffic accounting, billing, or security/anomaly analysis. Network engineers configuring cisco netflow monitoring use this MIB to pull NetFlow cache and template information directly over SNMP rather than only via the flow-collector protocol.
IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-NETFLOW-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- Cisco routers and switches
Monitoring Examples
An operator would poll cnfCIInterfaceTable/cnfCIInterfaceEntry to confirm cnfCINetflowEnable is set on the interfaces expected to be flow-monitored, then check cnfCICacheTable/cnfCICacheEntry for cnfCICacheType and cnfCICacheEnable to verify the cache is active. Watching cnfCIActiveFlows and cnfCIInactiveFlows against cnfCICacheEntries capacity flags a cache nearing exhaustion, which would cause dropped or aged-out flow records. cnfCIActiveTimeOut tuning affects how quickly long-lived flows are exported, which matters for accurate near-real-time traffic reporting.
What Can Be Monitored
- per-interface NetFlow enablement
- cache type and enablement
- active and inactive flow counts
- cache capacity/entries
- active flow timeout setting

How to Use in IPNetwork Monitor
Example using cnfESSampledPacket OID:
Select a Cisco router or switch (NetFlow) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type cnfESSampledPacket into the Find box to locate it in the OID tree, then select it and click OK. It reports the number of Sampled Packet. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

| ciscoNetflowMIB | 1.3.6.1.4.1.9.9.387 | The Netflow MIB provides a simple and easy method to get NetFlow cache information, current NetFlow configuration and statistics. It will enable medium to small size enterprises to take advantage of NetFlow technology over SNMP at a reduced infrastructure cost. The MIB is created to provide Netflow information in these areas: 1. Cache information and configuration. 2. Export information and configuration. 4. Export Statistics. 5. Protocol Statistics. 6. Version 9 Export Template information. 7. Top Flows information. Terminology used Flow A flow is defined as an unidirectional sequence of packets between a given source and destination endpoints. Network flows are highly granular; flow endpoints are identified both by IP address as well as by transport layer application port numbers. NetFlow also utilizes the IP Protocol type, Type of Service (ToS) and the input interface identifier to uniquely identify flows. Exporter A device (for example, a router) with NetFlow services enabled. The exporter monitors packets entering an observation point and creates flows out of these packets. The information from these flows are exported in the form of Flow Records to the collector. Flow Record A Flow Record provides information about an IP Flow that exists on the Exporter. The Flow Records are commonly referred to as NetFlow Services data or NetFlow data. Collector The NetFlow Collector receives Flow Records from one or more Exporters. It processes the received export packet, i.e. parses, stores the Flow Record information. The flow records may be optionally aggregated before storing into the hard disk. Template NetFlow Version 9 Export format is template based. Version 9 record format consists of a packet header followed by at least one or more template or data FlowSets. A template FlowSet (collection of one or more template) provides a description of the fields that will be present in future data FlowSets. Templates provide an extensible design to the record format, a feature that should allow future enhancements to NetFlow services without requiring concurrent changes to the basic flow-record format. One additional record type is also a part of Version 9 specification: an options template. Rather than supplying information about IP flows, options are used to supply meta-data about the NetFlow process itself. Top Flows. This feature provides a mechanism which allows the top N flows in the netflow cache to be viewed in real time. Criteria can be set to limit the feature to particular flows of interest, which can aid in DoS detection. Only the number of flows (TopN) and the sort criteria (SortBy) need be set. Top Flows is not intended as a mechanism for exporting the entire netflow cache. Egress flows. This feature provides a mechanism to identify a flow as either an ingress or an egress flow. | ||
