Performance Monitoring

Performance monitoring (PM) parameters are used by service providers to gather, store, set thresholds

for, and report performance data for early detection of problems. In this chapter, PM parameters and

concepts are defined for transponder, muxponder, and dense wavelength division multiplexing (DWDM)

cards in the Cisco ONS 15454 including optical amplifier, multiplexer, demutiplexer, optical add/drop

multiplexer (OADM), and optical service channel (OSC) cards.

Note Unless otherwise specified, “ONS 15454” refers to both ANSI and ETSI shelf assemblies.

For information about enabling and viewing PM values, refer to the Cisco ONS 15454 DWDM Procedure

Guide.
