Description: Monitors call admission, active call counts, and per-call statistics on Cisco Session Border Controller devices.

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-SESS-BORDER-CTRLR-CALL-STATS-MIB?

CISCO-SESS-BORDER-CTRLR-CALL-STATS-MIB monitors call and media statistics on Cisco Session Border Controller (SBC) devices that handle SIP and H.248 voice/video signaling, such as Cisco Unified Border Element (CUBE) platforms. It exposes global, periodic, and per-instance call statistics including active call counts, call setup rates, and available media flow counts, organized per SBC service instance. Its main monitoring value is service/software performance and capacity status: administrators track active call volume against capacity limits, watch call rate spikes that could signal a flood or outage, and confirm the SBC has sufficient available media flows to accept new sessions. The MIB ties its per-instance statistics to physical entities via csbCallStatsInstancePhysicalIndex, indicating a dependency on the standard ENTITY-MIB for hardware indexing. It is typically deployed on Cisco voice/video border-control platforms sitting at the edge of an enterprise or service-provider SIP trunking deployment. Engineers can download the CISCO-SESS-BORDER-CTRLR-CALL-STATS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-SESS-BORDER-CTRLR-CALL-STATS-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 Session Border Controller platforms (e.g., Cisco Unified Border Element/CUBE)

Monitoring Examples

An admin would poll csbCallStatsTable/Entry for csbCallStatsCallsHigh and csbCallStatsCallsLow to get the current active call count alongside csbCallStatsRate1Sec for the instantaneous call setup rate, keyed by csbCallStatsServiceIndex and csbCallStatsSbcName. If csbCallStatsAvailableFlows drops toward zero while csbCallStatsCallsHigh keeps climbing, the SBC is approaching its media-flow capacity and new calls may soon be rejected. Correlating this with csbCallStatsInstanceTable's csbCallStatsInstancePhysicalIndex helps pinpoint which hardware instance is under load.

What Can Be Monitored

  • active call count
  • call setup rate
  • available media flows
  • per-instance call statistics
  • SBC service/instance identity

How to Use in IPNetwork Monitor

Example using csbCallStatsUnclassifiedPkts OID:

Select a Cisco session border controller 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 csbCallStatsUnclassifiedPkts 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 number of unclassified packets processed by SBC. 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.
