What Is CISCO-MEDIA-METRICS-MIB?

CISCO-MEDIA-METRICS-MIB is a Cisco enterprise MIB that defines quality metrics for media (voice/video) streams as observed by a flow monitor — a hardware or software entity on Cisco devices that classifies traffic flows and periodically computes flow metrics. It exposes a media metrics table with per-flow validity flags, packet and octet counts, bit-rate and packet-rate measurements, and both current and peak stream bit-rate values. This is a real-time performance-monitoring MIB focused on software-level traffic quality rather than physical hardware: operators use cfmMediaMetricsBitRate, cfmMediaMetricsPktRate, and cfmMediaMetricsStreamBitRateMax to detect media streams that are degraded, congested, or exceeding expected bandwidth. It is a self-contained flow-monitoring MIB, generally used alongside Cisco's Medianet/flow-monitor infrastructure rather than depending on external IETF MIBs. It is deployed on Cisco routers and switches carrying VoIP or video traffic where per-flow media quality needs to be tracked in real time, and administrators can get the CISCO-MEDIA-METRICS-MIB download directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-MEDIA-METRICS-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 router
  • Cisco switch (flow-monitor capable)

Monitoring Examples

An administrator would poll cfmMediaMetricsTable/cfmMediaMetricsEntry, checking cfmMediaMetricsValid to confirm the entry reflects an active flow, then reading cfmMediaMetricsPkts, cfmMediaMetricsOctets, and cfmMediaMetricsBitRate (with cfmMediaMetricsBitRateUnits) to assess current throughput of a media stream. Comparing cfmMediaMetricsStreamBitRate against cfmMediaMetricsStreamBitRateMax reveals whether a video call is currently running near its peak observed bandwidth, which combined with a low cfmMediaMetricsPktRate could indicate packet loss or stream stalling. This data is typically correlated with jitter/MOS data from companion IP SLA or Medianet MIBs for a full quality picture.

What Can Be Monitored

  • per-flow packet and octet counts
  • current bit rate and packet rate
  • stream bit rate vs. peak bit rate
  • flow entry validity

How to Use in IPNetwork Monitor

Example using cfmMediaMetricsPkts OID:

Select a Cisco router/switch (flow-monitor capable media metrics) 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 cfmMediaMetricsPkts 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. This object indicates the total number of packets, containing media payload, processed by the corresponding flow monitor for the corresponding traffic flow. 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 (in packets), 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.
