Each trace message provides the date, time, and name of the Dell 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.
