Exception information for the switch is stored in the ash:/TRACE_LOG_DIR directory. This directory contains les that save trace
information when there has been a task crash or timeout and trace information from the Route Processor and Control Processor CPUs.
You can access the TRACE_LOG_DIR les by FTP or by using the show file command from the ash://TRACE_LOG_DIR directory.
Uploading Trace Logs
To upload a trace-log le from a switch CPU, use the upload trace-log command.
When the upload trace log command is issued, the trace log information is uploaded to ash:/TRACE_LOG_DIR.
