Trace Logs
In addition to the syslog buer, Dell Networking OS buers trace messages which are continuously written by various Dell
Networking OS 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 buer.
You can save the messages to a le either manually or automatically after failover.
Auto Save on Crash or Rollover
Exception information for MASTER or standby units 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.
• On a MASTER unit, you can reach the TRACE_LOG_DIR les by FTP or by using the show file command from the ash://
TRACE_LOG_DIR directory.
• On a Standby unit, you can reach the TRACE_LOG_DIR les only by using the show file command from the ash://
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
