Performance Monitoring - Cisco ONS 15600 Reference Manual

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.
This chapter defines PM parameters and concepts for Cisco ONS 15600 SDH optical cards. You can use
performance monitoring (PM) parameters to gather, store, threshold, and report performance data for
early detection of problems.
For additional information regarding PM parameters, refer to ITU-T G.826, G.827, G.828, G.829,
Note
M2101, and M2102, or Telcordia documents GR-1230-CORE, GR-820-CORE, GR-499-CORE, and
GR-253-CORE and the ANSI T1.231 document entitled Digital Hierarchy - Layer 1 In-Service Digital
Transmission Performance Monitoring.
For information about enabling and viewing PM values, refer to the Cisco ONS 15600 SDH Procedure
Guide.

12.1 Threshold Performance Monitoring
Thresholds are used to set error levels for each PM. You can program PM threshold ranges from the
Provisioning > SDH Thresholds tabs on the Cisco Transport Controller (CTC) card view. To provision
card thresholds, such as line, path, and SDH thresholds, refer to the Cisco ONS 15600 SDH Procedure
Guide.
