What Is CISCO-FLOW-MONITOR-TC-MIB?
CISCO-FLOW-MONITOR-TC-MIB is a Cisco MIB that defines shared textual conventions (data types and enumerations) used by Cisco's flow-monitoring MIB modules, covering concepts like flow direction, sampler types, match-field definitions, and alarm terminology (alarm action, alarm aggregation, alarm condition, alarm group). It does not itself define runtime data tables or counters; instead it supplies the common vocabulary that other Cisco flow-monitoring MIBs (such as those for NetFlow/Flexible NetFlow sampling and alarms) build upon. Because it only defines types, it has no direct role in reporting live hardware or software status, but the alarm-related conventions it defines underpin how dependent MIBs represent standing fault/alarm conditions for flow monitoring. A CISCO-FLOW-MONITOR-TC-MIB download is generally obtained together with the dependent flow-monitoring modules that actually import its type definitions, since the file alone provides no pollable objects and it is inherently dependent on and shared with Cisco's broader flow-monitoring MIB family. It would be found loaded alongside other Cisco flow/NetFlow MIBs on Cisco routers and switches that support flow-based traffic monitoring.
IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-FLOW-MONITOR-TC-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 Catalyst 9300 Series — current-gen access switch with Flexible NetFlow support
- Cisco Catalyst 9500X Series — current-gen core switch with ingress Flexible NetFlow
Monitoring Examples
This module defines only textual conventions (data types and enumerations) and includes no runtime data objects or tables of its own, so no concrete monitoring/polling scenario applies; it is consumed by other Cisco MIBs that import these type definitions.

| ciscoFlowMonitorTcMIB | 1.3.6.1.4.1.9.9.688 | This MIB module defines textual conventions used by the MIB modules defining objects describing flow monitoring. GLOSSARY ============ Alarm Action - a method used by the device to signal changes in an alarm condition. Alarm Aggregation - a technique used to efficiently monitor the same standing condition for a flow set. Alarm Condition - a standing condition for which the device signals changes in state. Alarm Group - a flow set for which the device monitors a configured standing condition, raising an alarm when a configured number of flows in the flow set assert the standing standing. Alarm Severity - the relative disposition of an alarm condition when raised by the device. For example, a provider may regard a flow stop alarm as having a higher severity than a flow's loss fraction exceeding a configured threshold. Flow Monitor - a hardware or software entity that classifies traffic flows, collects flow data, and periodically computes flow metrics. Flow Metric - a measurement that reflects the quality of a traffic flow. Flow Point - represents the ingress or egress of a traffic flow. Flow Set - a group of traffic flows. Measurement Interval - the length of time over which a flow monitor collects data related to a traffic flow, after which the flow monitor computes flow metrics using the collected data. Standing Condition - represents a lasting error, fault, or warning resulting from the application of a set of criteria to the state of an entity, such as a flow monitor or traffic flow. For example, a flow monitor may assert a standing condition if the number of traffic flows that expire in a meansurement interval exceeds a configured threshold. Traffic Flow - a unidirectional stream of packets conforming to a classifier. For example, packets having a particular source IP address, destination IP address, protocol type, source port number, and destination port number. |
