TRACE Logs

In addition to the syslog buffer, to report hardware and software events and status information, Dell
Networking OS buffers trace messages which are continuously written by various Dell Networking OS
software tasks.
Each TRACE message provides the date, time, and name of the Dell Networking OS 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 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.
NOTE: Non-management member units do not support this functionality.

Last Restart Reason

If a Z9000 system restarted 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.

Line Card Restart Causes and Reasons

Causes
Remote power cycle of the chassis

reboot after a crash

Hardware Watchdog Timer

The hardware watchdog command automatically reboots an Dell Networking OS switch/router when a
unit is unresponsive.
This is a last resort mechanism intended to prevent a manual power cycle.
