Each trace message provides the date, time, and name of the Dell EMC Networking OS process. All messages are stored in a ring buffer. You can save the messages to a file either manually or automatically after failover. Auto Save on Crash or Rollover Exception information for MASTER or standby units 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. • On a MASTER unit, you can reach the TRACE_LOG_DIR files by FTP or by using the show file command from the flash:// TRACE_LOG_DIR directory. • On a Standby unit, you can reach the TRACE_LOG_DIR files only by using the show file command from the flash:// TRACE_LOG_DIR directory. NOTE: Non-management member units do not support this functionality. Last Restart Reason If the system restarts for some reason (automatically or manually), the show system command output includes the reason for the restart. The following table shows the reasons displayed in the output and their corresponding causes. Debugging and Diagnostics 1109
