Performance Monitoring


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, 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

Chapter topics include:

15.1 Threshold Performance Monitoring, page 15-1

15.2 Intermediate-Path Performance Monitoring, page 15-2

15.3 Pointer Justification Count Performance Monitoring, page 15-3

15.4 Performance Monitoring for Electrical Cards, page 15-3

15.5 Performance Monitoring for Ethernet Cards, page 15-14

15.6 Performance Monitoring for Optical Cards, page 15-21

15.7 Performance Monitoring for the Fiber Channel Card, page 15-54

For additional information regarding PM parameters, refer to ITU G.826, and Telcordia documents
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
