Description: Juniper Networks MIB for monitoring ATM pseudowire emulation statistics and parameters on Juniper PE router 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 JUNIPER-PW-ATM-MIB?

JUNIPER-PW-ATM-MIB is a Juniper Networks private MIB for monitoring ATM pseudowire emulation (ATM over MPLS/PWE3) on Juniper PE routers. Although no sample objects were supplied, based on its description it would expose configuration and statistics for individual ATM pseudowires such as cell counts, cell-loss/error counts, and pseudowire operational state, layered on top of the generic PW-MIB/PW-ATM-MIB framework. As such it is used to monitor the software/service status of pseudowire circuits -- whether a pseudowire is up, and whether cells are being dropped or errored -- rather than physical chassis hardware like fans or power supplies. It depends on the IETF PW-STD-MIB/PW-ATM-STD-MIB structures, adding Juniper-specific extensions. It is typically deployed on Juniper MX/M-series routers providing legacy ATM circuit emulation services over an MPLS core, tracked via JUNIPER-PW-ATM-MIB SNMP monitoring of pseudowire status.

IPNetwork Monitor allows you to monitor SNMP objects defined in JUNIPER-PW-ATM-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

  • Juniper Networks MX/M-series routers (PE routers with ATM PWE3 support)

Monitoring Examples

No sample objects were provided for this module, so specific table names cannot be confirmed from source; based on the description, a realistic scenario would be polling per-pseudowire cell counters and operational status objects to detect a pseudowire that has gone down or is experiencing cell loss, which would indicate an MPLS transport or ATM interface problem.

What Can Be Monitored

  • pseudowire operational status
  • ATM cell counts
  • cell loss/error counts
  • pseudowire configuration
