What Is NETFLOW-MIB?

This NETFLOW-MIB is a BDCOM enterprise MIB exposing NetFlow traffic-accounting functionality over SNMP, providing a simple way to retrieve NetFlow cache contents, configuration, and export statistics without a dedicated collector. It belongs to the traffic-monitoring/flow-accounting technology area and covers per-interface NetFlow enablement, cache configuration/statistics (entries, used/unused entries, active/inactive timeouts), and collector/export configuration and statistics. For monitoring device software status it reveals whether NetFlow is enabled on a given interface, how full the flow cache is (indicating whether it is being exhausted under high traffic load), and whether exported flow records are reaching the configured collector. It is a self-contained BDCOM enterprise MIB that mirrors Cisco's NetFlow model conceptually rather than importing a standard NetFlow/IPFIX MIB. It is typically deployed on BDCOM carrier-class or metro Ethernet switches/routers used for traffic accounting and network visibility. Network engineers evaluating or troubleshooting this functionality can download the NETFLOW-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in 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.

What Can Be Monitored

per-interface NetFlow enable status
flow cache entries used vs. available
active/inactive flow timeout settings
NetFlow collector configuration
flow export statistics

Supported Devices

BDCOM carrier/metro Ethernet switch or router

Monitoring Examples

An operator checks netflowInterfaceTable/netflowInterfaceEntry to confirm netflowCacheNetflowEnable is set on the interfaces expected to export flow data, then polls netflowCacheTable/netflowCacheEntry for netflowCacheEntries, netflowUsedEntries, and netflowUnUsedEntries to see how full the flow cache is — a netflowUsedEntries value close to netflowCacheEntries signals the cache is near capacity. Reviewing netflowActiveTimeOut and netflowInactiveTimeOut confirms how aggressively flows are aged out, and the netflowCollectorInfo branch is checked to verify the configured NetFlow collector is receiving exports.

OIDs

OID symbolic	OID numeric	Type	Access	Description

netflowMIB	1.3.6.1.4.1.3320.9.226			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. Collector information and configuration. 3. Export Statistics. 4. Version 9 Export Template information. Terminology used Flow A flow is defined as a unidirectional sequence of packets with some common properties that pass through a network device. These collected flows are exported to an external device, the NetFlow collector. Network flows are highly granular; for example, flow records include details such as IP addresses, packet and byte counts,timestamps, Type of Service (ToS), application ports, input and output interfaces, etc. 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, display the Flow Record information. The flow records may be optionally aggregated before being stored 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 information about the NetFlow process configuration or NetFlow process specific data.

netflowMIB	1.3.6.1.4.1.3320.9.226			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. Collector information and configuration. 3. Export Statistics. 4. Version 9 Export Template information. Terminology used Flow A flow is defined as a unidirectional sequence of packets with some common properties that pass through a network device. These collected flows are exported to an external device, the NetFlow collector. Network flows are highly granular; for example, flow records include details such as IP addresses, packet and byte counts,timestamps, Type of Service (ToS), application ports, input and output interfaces, etc. 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, display the Flow Record information. The flow records may be optionally aggregated before being stored 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 information about the NetFlow process configuration or NetFlow process specific data.
