This document uses a simple test topology to describe how to troubleshoot Multi−Layer (ML) cards on Cisco
ONS 15454. The Appendix section provides some basic configuration commands, and detailed topology
information.

The test uses an empirical approach to understand the network faults associated with ML cards. The test
injects known faults or configurations in order to capture and analyze expected results. The Fault Isolation
Case Studies present these findings.

The document follows the typical troubleshooting methodologies. The document presents a symptom, and
discusses the relevant fault isolation steps, and also provides generic troubleshooting procedures.
