Performance Monitoring
The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms
Note
do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration.
Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's
path protection feature, which may be used in any topological network configuration. Cisco does not
recommend using its path protection feature in any particular topological network configuration.
Performance monitoring (PM) parameters are used by service providers to gather, store, set thresholds,
and report performance data for early detection of problems. In this chapter, PM parameters and concepts
are defined for electrical cards, Ethernet cards, and optical cards in the Cisco ONS 15454 SDH.
For information about enabling and viewing PM values, refer to the Cisco ONS 15454 SDH Procedure
Guide.
Chapter topics include:
For additional information regarding PM parameters, refer to ITU G.826, and Telcordia documents
Note
GR-820-CORE, GR-499-CORE, and GR-253-CORE.
15.1 Threshold Performance Monitoring
Thresholds are used to set error levels for each PM parameter. You can set individual PM threshold
values from the Cisco Transport Controller (CTC) card view Provisioning tab. For procedures on
provisioning card thresholds, such as line, path, and SDH thresholds, refer to the Cisco ONS 15454 SDH
Procedure Guide.

    Thresholds are used to set error levels for each PM parameter. You can set individual PM threshold values from the Cisco Transport Controller (CTC) card view Provisioning tab. For procedures on provisioning card thresholds, such as line, path, and SDH thresholds, refer to the Cisco ONS 15454 SDH Procedure Guide.

  • Page 2: Intermediate-path Performance Monitoring

    IPPM is not supported. However, SDH path PM parameters can be monitored by logging into the far-end node directly. The ONS 15454 SDH performs IPPM by examining the overhead in the monitored path and by reading all of the near-end path PM values in the incoming direction of transmission. The IPPM process allows the path signal to pass bidirectionally through the node completely unaltered.

    You must enable PPJC and NPJC performance monitoring parameters for LTE cards. See page 15-2 for a list of Cisco ONS 15454 SDH LTE cards. In CTC, the count fields for PPJC and NPJC PM parameters appear white and blank unless they are enabled on the card view Provisioning tab.
