OAM-PM Loss (NSP) report

Overview

The OAM-PM Loss (NSP) report differs from the OAM-PM Loss report by including OAM data for NEs managed by the NFM-P and MDM (model-driven Nokia NEs). The report can be run by itself or as a drill-down from an OAM-PM Network Site Summary (NSP) report. The report shows the graph of loss data for a selected session during a specified time period.

The report includes the following session types:

ETH-CFM Session
TWAMP-Light Session

Use cases

QoS analysis—Identify potential service impacting issues based on thresholds for latency, jitter and packet loss between specific NEs.

Prerequisites

The following sessions need to be performed in the NSP and NFM-P for the report to be created:

a DMM session must be defined with accounting enabled in both the MDM-managed and NFM-P NEs
a TWAMP-Light session must be defined with accounting enabled in both the MDM-managed and NFM-P NEs
You must enable aggregation using NSP. For more information, see the Telemetry information on the Network Developer Portal and the NSP Data Collection and Analysis Guide.
