What Is ATMSWCH-MIB?

ATMSWCH-MIB is a Lucent Technologies vendor-specific MIB for managing ATM switch fabric hardware, modeling per-CPU-card health (atmSwchCpuTable: atmSwchCpuUtilization, atmSwchCpuRamUsed/Size, atmSwchCpuFlashUsed/Size, atmSwchCpuSysUpTime), per-slot state including SONET Automatic Protection Switching (atmSwchSlotAPSMode, atmSwchSlotAPSCurrentState, atmSwchSlotAPSSwitchCommand, atmSwchSlotAPSSFBerThreshold), and per-port/per-virtual-port configuration and connection counts (atmSwchPortTable, atmSwchVPortTable) covering SVC/PVC point-to-point and point-to-multipoint connection tallies, signalling state, and ILMI address registration. It also tracks cross-connect-adjacent objects such as atmSwchPortdsx3CellMaping for DS3-to-cell mapping and atmSwchVPortConfMinVpi/MaxVpi for VPI range provisioning on each virtual port, giving visibility into both switch-fabric resource utilization and connection-level state. This MIB is useful for spotting overloaded switch CPU cards, APS protection switches that have triggered due to bit-error-rate thresholds, or virtual ports stuck out of their expected signalling/ILMI state, and it is deployed on Lucent ATM switch platforms; network teams managing Lucent ATM gear can search for the ATMSWCH-MIB MIB reference when building monitoring for these switches.

IPNetwork Monitor allows you to monitor SNMP objects defined in ATMSWCH-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

  • Lucent Technologies ATM switch platforms

Monitoring Examples

An operator polls atmSwchSlotTable (indexed by atmSwchSlotIndex) to check atmSwchSlotAPSCurrentState against atmSwchSlotAPSSFBerThreshold; a slot reporting an active protection-switch state alongside a high atmSwchSlotRxCellDiscards count would indicate a degraded SONET line triggered an APS failover.

What Can Be Monitored

  • per-CPU-card utilization and memory/flash usage
  • APS protection-switching state and BER thresholds
  • per-port SVC/PVC point-to-point and multipoint connection counts
  • virtual port signalling and ILMI registration state
  • receive-cell discard counters per slot
