Description: MIB for configuration, interface management, bandwidth, and statistics on IBM ATM switching node hardware

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 ATM-SWITCHING-NODE-MIB?

ATM-SWITCHING-NODE-MIB provides configuration, interface management, bandwidth, and statistics objects for IBM ATM switching node hardware. It exposes a switch table of administrative and operational state per slot, a module inventory table, and overall system state tracking. Its monitoring emphasis is on hardware status: per-slot admin/operational state and the timestamp of the last system state change reveal when a switching module has gone operationally down or when the node as a whole last transitioned state, both signs of a hardware fault. It is an IBM proprietary MIB that likely works alongside the standard ATM-MIB for interface-level statistics on the same node. It is used on IBM ATM switching nodes in legacy campus or backbone ATM networks. Engineers can download the ATM-SWITCHING-NODE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ATM-SWITCHING-NODE-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

  • IBM ATM switching node

Monitoring Examples

switchTable/switchEntry, indexed by switchSlotIndex, exposes switchAdminState and switchOperState, alongside a moduleTable for module inventory and top-level systemState and lastChange objects. An administrator would poll switchOperState per switchSlotIndex to detect a switching module that has gone operationally down, and check systemState and lastChange together to see when the node's overall state last transitioned, correlating that with a recent hardware fault.

What Can Be Monitored

  • per-slot switch admin/operational state
  • module inventory/status
  • overall system state
  • time of last state change
  • IP ARP server ATM address

How to Use in IPNetwork Monitor

Example using switchAggregateOutCells OID:

Select an IBM ATM switching node equipment (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 switchAggregateOutCells into the Find box to locate it in the OID tree, then select it and click OK. The total number of cells transmitted from the switch. 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 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.
