Description: Manages ATM virtual circuit connections (PVCs/SVCs) on Cisco 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-ATM-CONN-MIB?

CISCO-ATM-CONN-MIB is a Cisco extension to the standard ATM connection tables defined in RFC 1695, adding vendor-specific management for ATM virtual path/virtual channel (VPL/VCL) connections on Cisco ATM switching platforms. It exposes per-connection configuration and status such as cast type, span type, connection state, UPC/policing mode, and OAM loopback and AIS/RDI (alarm indication/remote defect indication) settings. Its monitoring purpose is connection- and fault-status tracking on ATM switches: an operator checks ciscoAtmVplConnState to confirm a virtual path is up, and monitors OAM AIS/RDI flags to detect upstream/downstream ATM fault conditions propagating through the network. It directly extends and depends on the standard ATM-MIB (RFC 1695) VPL/VCL tables rather than replacing them. It is used in legacy carrier and enterprise ATM switching deployments, increasingly rare today but still found in older telecom/WAN infrastructure running ATM PVCs/SVCs. Engineers can download the CISCO-ATM-CONN-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-ATM-CONN-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 ATM switches

Monitoring Examples

An admin polls ciscoAtmVplTable/Entry to check ciscoAtmVplConnState and ciscoAtmVplOamAisEnable/ciscoAtmVplOamRdiEnable for a given virtual path. A connection state that isn't "operational" alongside an active AIS condition would indicate an ATM fault upstream of the switch, such as a failed transmission facility, propagating an alarm indication signal down the path.

What Can Be Monitored

  • ATM virtual path connection state
  • cast type/span type configuration
  • UPC/policing mode
  • OAM loopback settings
  • AIS/RDI alarm indication status

How to Use in IPNetwork Monitor

Example using ciscoAtmVplInClp0Cells OID:

Select a Cisco ATM switch 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 ciscoAtmVplInClp0Cells into the Find box to locate it in the OID tree, then select it and click OK. The total number of cells with the CLP bit clear received on this VPL. 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.
