Description: Defines managed objects for monitoring and managing High Performance Routing (HPR) over IP in IBM SNA/APPN networks.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring HPR-IP-MIB with a free 30-day trial of IPNetwork Monitor.

What Is HPR-IP-MIB?

HPR-IP-MIB is an IETF/vendor-neutral standards MIB for managing High Performance Routing (HPR) carried over IP within IBM SNA/APPN networks. It defines two functional groups: a monitoring group that counts UDP packets sent per APPN traffic type by each link station, and a configuration group that maps APPN traffic types to IP TOS precedence values at the APPN port level. Its monitoring value is primarily software/protocol traffic status rather than physical hardware: operators track per-traffic-type UDP packet counts on active link stations to gauge protocol activity and confirm that QoS-relevant TOS mappings are correctly applied and inherited down to connection networks and link stations. It explicitly depends on APPN/HPR concepts and is meant to be used alongside the base HPR-MIB, which covers HPR routing objects more broadly. It is deployed in legacy IBM SNA/APPN network environments that tunnel HPR traffic over IP infrastructure. Engineers implementing or auditing this functionality typically reference the HPR-IP-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in HPR-IP-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

  • vendor-neutral, standards-based MIB, not tied to a specific manufacturer
  • IBM SNA/APPN network nodes/routers carrying HPR over IP

Monitoring Examples

An administrator would poll hprIpActiveLsTable (hprIpActiveLsEntry) to see each active link station's hprIpActiveLsLsName, hprIpActiveLsAppnTrafficType, and hprIpActiveLsUdpPackets, watching for a traffic type whose packet count stalls or drops unexpectedly, which could indicate a stalled HPR session. Separately, reading hprIpAppnPortTable's hprIpAppnPortTOSPrecedence per hprIpAppnPortAppnTrafficType confirms whether QoS-sensitive traffic types are being marked with the expected IP precedence, helping diagnose why time-sensitive SNA traffic is experiencing unexpected latency.

What Can Be Monitored

  • UDP packets sent per APPN traffic type
  • active link station traffic type
  • APPN port TOS precedence mapping
  • link station name/identity

How to Use in IPNetwork Monitor

Example using hprIpActiveLsUdpPackets OID:

Select an IBM SNA/APPN network node/router carrying HPR over IP 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 hprIpActiveLsUdpPackets 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 count of outgoing UDP packets carrying this type of APPN traffic. 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.
