Description: Defines managed objects for Dynamic Flow Capture (DFC) on Juniper Networks devices, supporting selective packet capture and traffic mirroring.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is JUNIPER-DFC-MIB?

JUNIPER-DFC-MIB is Juniper Networks' enterprise-specific MIB for Dynamic Flow Capture (DFC), a feature used for selective packet capture and traffic mirroring on Juniper routing platforms, often in support of lawful intercept and forensic traffic analysis. It exposes configuration and status data describing capture filters, target flows, and mirroring destinations rather than general system health metrics. In practice it is used to monitor whether flow-capture rules are active and correctly redirecting matched traffic, serving as a software-status indicator for the DFC feature rather than hardware sensors. As an enterprise MIB it builds on standard SNMPv2 SMI conventions and Juniper's private enterprise OID tree, and may reference interface indices from IF-MIB for the ports involved in capture. It is typically deployed in service-provider or enterprise networks where selective, on-demand packet mirroring is required for security or compliance purposes. Engineers can download the JUNIPER-DFC-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in JUNIPER-DFC-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

  • Juniper Networks router

Monitoring Examples

No sample objects were provided for this module in the source data, so specific object names cannot be cited; based on the module description, an administrator would poll DFC configuration/status objects to confirm a capture filter is enabled and actively diverting matching traffic to its mirror destination. A discrepancy between expected and actual capture state (e.g., a filter that should be active showing inactive) would signal a misconfiguration or failed activation. Because no object list was supplied, further table/column-level detail cannot be responsibly invented.

How to Use in IPNetwork Monitor

Example using jnxDfcCSControlProtocolAddRequests OID:

Select a Juniper Networks router (Dynamic Flow Capture, lawful intercept/forensics) 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 jnxDfcCSControlProtocolAddRequests into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the total number of Control protocol Add requests received. 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 Counter64-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.
