Performance Monitoring
Note The terms “Unidirectional Path Switched Ring” and “UPSR” may appear in Cisco literature. These terms
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, threshold, 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 15310-MA SDH.
For information about enabling and viewing PM parameters, refer to the Cisco ONS 15310-MA SDH
Procedure Guide.
Chapter topics include:
• 11.1 Threshold Performance Monitoring, page 11-1
• 11.2 Intermediate-Path Performance Monitoring, page 11-3
• 11.3 Pointer Justification Count Performance Monitoring, page 11-3
• 11.4 Performance Monitoring Parameter Definitions, page 11-4
• 11.5 Performance Monitoring for Electrical Ports, page 11-13
• 11.6 Performance Monitoring for Ethernet Cards, page 11-19
• 11.7 Performance Monitoring for Optical Ports, page 11-25
Note When circuits transition from the out-of-service state to the in-service state, the performance monitoring
counts during the out-of-service circuit state are not part of the accumulation cycle.

11.1 Threshold Performance Monitoring

Thresholds are used to set error levels for each PM parameter. You can program PM parameter threshold
ranges from the Provisioning > Line Thresholds tab in card view. For procedures for provisioning card
thresholds, such as line, path, and SDH thresholds, refer to the Cisco ONS 15310-MA SDH Procedure
Guide.
