Description: Manages Ericsson MINI-LINK microwave radio performance management data collection, intervals, and threshold configuration.

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 PT-PM-MIB?

PT-PM-MIB is a proprietary Ericsson MIB used within the MINI-LINK family of microwave radio transmission products, placing it in the telecom microwave/point-to-point radio transport technology area. It manages Performance Monitoring (PM) data collection: configuring measurement intervals, threshold values, and exposing the resulting performance counters gathered from the radio link. It is used explicitly for monitoring the operational performance status of the radio hardware, since PM threshold crossings on signal-quality or error counters serve as an early warning of degrading link/hardware condition even before a hard fault occurs. It likely follows general telecom performance-monitoring conventions (in the spirit of RFC 2493) and works alongside other MINI-LINK-specific MIBs that expose the underlying radio hardware inventory and alarms. It is typically deployed on Ericsson MINI-LINK microwave radio nodes used for cellular backhaul or fixed point-to-point wireless transport links, where PT-PM-MIB SNMP monitoring of performance counters provides early warning of link degradation.

IPNetwork Monitor allows you to monitor SNMP objects defined in PT-PM-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.

Monitoring Examples

No sample object or table names were supplied for this module, so a concrete object-level polling scenario cannot be honestly given. Generically, an operator would configure a PM interval and threshold via this MIB and then poll the resulting counters/threshold-state objects to detect when a MINI-LINK radio's performance (e.g., signal degradation) crosses the configured limit, prompting investigation of the physical radio link.

What Can Be Monitored

How to Use in IPNetwork Monitor

Example using forwardingPacket OID:

Select an Ericsson MINI-LINK microwave radio link (performance monitoring counters) 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 forwardingPacket 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. The number of packets that have been sent from the queue. 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 Counter64-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.
