TRACE Logs In addition to the syslog buffer, to report hardware and software events and status information, the system buffers trace messages which are continuously written by various software tasks. Each TRACE message provides the date, time, and name of the system process. All messages are stored in a ring buffer that you can save to a file either manually or automatically after failover. Auto Save on Reload, Crash, or Rollover Exception information for the switch is stored in the flash:/TRACE_LOG_DIR directory. This directory contains files 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 files by FTP or by using the show file command from the flash:// TRACE_LOG_DIR directory. Uploading Trace Logs To upload a trace-log file 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 flash:/ TRACE_LOG_DIR. Parameters • rp - Enter the keyword rp to upload a trace log from the Route Processor CPU. • linecard slot-id - Enter the linecard slot-id parameters to specify the line-card CPU whose trace log you want to upload. • hw-trace - Enter the keyword hw-trace to upload the hardware trace log from the specified CPU. • sw-trace - Enter the keyword sw-trace to upload the software trace log from the specified CPU. • pe pe-id - Enter the keyword pe and port extender ID. Range is 0- 255. • stack-unit number - Enter the keyword stack-unit and a stack unit number. Stack unit range is 0 -7. • Upload a trace-log file from a switch CPU.
