Trace Logs
In addition to the syslog buffer, the Dell Networking OS buffers trace messages which are continuously
written by various software tasks to report hardware and software events and status information.
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.
