Description: Manages Cisco WAN Switched Virtual Circuit (SVC) configuration and call control on ATM platforms.

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-WAN-SVC-MIB?

CISCO-WAN-SVC-MIB is a vendor-specific MIB for Cisco's BPX-SES and MGX ATM WAN switching platforms, describing ATM network services including Switched Virtual Circuit (SVC) call control, provisioning, and status gathering, using ATM/PNNI terminology such as ABR, AINI, and ENNI. It exposes configuration data (software revision, controller status) and connection-oriented protocol state, notably SSCOP (Service Specific Connection Oriented Protocol) timer and status tables used in signaling between ATM switches. Its monitoring value spans both hardware/software status (controller and standby-controller operational state, software revision) and protocol-layer health (SSCOP connection timers governing PNNI/AINI signaling links), letting an operator confirm that ATM signaling adjacencies between switches remain stable and that redundant controllers are correctly synchronized. It is closely tied to standard ATM and PNNI signaling concepts and to Cisco's broader WAN switching MIB family for the BPX-SES/MGX product lines. It is deployed on Cisco BPX-SES and MGX ATM switches in carrier/enterprise ATM backbone networks providing SVC-based connectivity. Network engineers evaluating or troubleshooting this functionality can download the CISCO-WAN-SVC-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-WAN-SVC-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 BPX-SES ATM switch
  • Cisco MGX ATM switch

Monitoring Examples

An administrator would check cwsControllerStatus and cwspPnniStndbyControllerStatus / cwspPnniControllerStatus (with cwspPnniControllerPhySlot identifying the physical slot) to confirm the active and standby PNNI controllers are both healthy and correctly synchronized. Polling cwspSscopTable / cwspSscopEntry for timer values like cwspSscopTmrKeepAlive, cwspSscopTmrNoResp, and cwspSscopTmrPoll would reveal whether an SSCOP signaling link to a neighboring switch is stable or repeatedly timing out, which would indicate an ATM inter-switch signaling adjacency problem affecting SVC call setup. cwsSwRevision lets the operator confirm the running software version matches the expected baseline across redundant controllers.

What Can Be Monitored

  • active/standby ATM controller status
  • software revision
  • SSCOP signaling timers
  • PNNI controller physical slot status
  • SVC call/service configuration

How to Use in IPNetwork Monitor

Example using cwspSscopIgnoredPduRcv OID:

Select a Cisco BPX-SES/MGX ATM switch (legacy) 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 cwspSscopIgnoredPduRcv 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 stores the number of SSCOP PDUs that are received but ignored due to incorrect size, invalid PDU, unknown PDU type. 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 Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
