Description: Manages storm control thresholds for broadcast, multicast, and unicast traffic on Cisco switch ports.

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 CISCO-PORT-STORM-CONTROL-MIB?

CISCO-PORT-STORM-CONTROL-MIB is a Cisco proprietary MIB that manages the per-port storm control feature, letting a Network Management Station configure and monitor broadcast, multicast, unicast, or combined traffic-rate limiting on physical interfaces. cpscThresholdTable, indexed by ifIndex and traffic type, holds cpscUpperThreshold and cpscLowerThreshold as hundredths-of-a-percent of interface bandwidth that trigger and clear a storm event, while cpscActionTable configures whether the response is to filter(1) or shutdown(2) the port and controls notification generation via cpscNotificationControl. cpscStatusTable reports live state through cpscStatus (inactive, forwarding, trafficTypeFiltered, allTrafficFiltered, or shutdown), cpscCurrentLevel, and cpscSuppressedPacket counts, and cpscHistoryTable retains a rolling log of past storm events with cpscHistoryStartTime/EndTime. The cpscEventRev1 notification (replacing the deprecated cpscEvent) alerts an NMS in real time when a storm is declared or clears. It is deployed on Cisco LAN switches for CISCO-PORT-STORM-CONTROL-MIB MIB based broadcast/multicast/unicast storm detection and mitigation.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-PORT-STORM-CONTROL-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 LAN switches

Monitoring Examples

An operator polls cpscStatus and cpscCurrentLevel for a given ifIndex/traffic-type pair to check whether a port is actively filtering traffic, and reviews cpscSuppressedPacket alongside cpscHistoryTable entries; a cpscStatus of allTrafficFiltered combined with a rapidly growing cpscSuppressedPacket counter would indicate an active broadcast storm on that port requiring root-cause investigation upstream.

What Can Be Monitored

  • per-port storm-control upper/lower thresholds
  • configured storm-control action (filter/shutdown)
  • live storm-control status and current traffic level
  • suppressed packet counters
  • storm event history (start/end times)
  • storm notification control settings

How to Use in IPNetwork Monitor

Example using cpscSuppressedPacket OID:

Select a Cisco LAN switch (storm control) 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 cpscSuppressedPacket 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 represents the total number of packets of a particular traffic type that have been suppressed on a given interface by storm control filter action. 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.
