OAM report overview

General information

OAM reports show aggregated latency and loss information based on results of OAM testing. Information in the report inputs is optimized to reflect the configuration of the test in the NFM-P GUI, for example, only configured forwarding classes appear in the inputs.

Forwarding classes are highlighted when latency or packet loss exceeds thresholds:

• Orange highlighting indicates that the maximum RTD is double or more the value of the average RTD

• Yellow highlighting indicates that the loss is greater than 0% but less than 5%.

• Red highlighting indicates that the loss is greater than 5%.

Note: Gaps may appear in line graphs: these indicate a time during which no data was available.

Both the NE name and its IP address display in the report.

Drill-down reports

All OAM reports can be run from the main OAM reports folder. Some reports can also be run as drill-downs by clicking on a data point in another report.

The following table shows the drill-downs available for OAM reports. Each level of indentation indicates a drill down. For example, OAM-PM Network Site Summary is a drill-down report from an OAM-PM Network Summary report. OAM-PM Latency and OAM-PM Loss reports are drill-downs from an OAM-PM Network Site Summary report.

Prerequisites

The following must be configured for OAM reports to be created:

• OAM testing must be configured in the NFM-P.

  See the following in the NSP NFM-P Classic Management User Guide for information about the tests and policies that provide data for OAM reports:

  • PM bin group policies

  • Configuring a CFM two way delay OAM diagnostic test from the STM

  • Configuring a PM session OAM diagnostic test from the STM

  • Configuring a CFM DMM session OAM diagnostic test from the STM

  • Configuring a TWAMP-Light session OAM diagnostic test from the STM

  • Creating and running an ICMP ping OAM diagnostic test from the STM

  • Creating and running a VCCV ping OAM diagnostic test from the STM

• The OAM test results must be stored in the auxiliary database. To enable auxiliary database storage of OAM test results, you must enable the oam-test-results parameter in the samauxdb section of each NFM-P main server configuration. See the NSP Installation and Upgrade Guide for information about using the samconfig utility to modify the NFM-P configuration.

• OAM statistics must be collected using an accounting policy:

  • ETH-CFM Two-Way Delay, ICMP Ping, and VCCV Ping tests require an NE Schedulable Tests policy.

  • ETH-CFM Session and TWAMP-Light Session tests require a Complete-PM policy.

• To view the reports for granularities other than raw data, the OAM aggregation rules must be enabled; see How do I configure analytics aggregation?.
