Trace Logs
In addition to the syslog buffer, the Dell Force10 operating software (FTOS) buffers trace messages which
are continuously written by various FTOS software tasks to report hardware and software events and status
information. Each trace message provides the date, time, and name of the FTOS process. All messages are
stored in a ring buffer and can be saved to a file either manually or automatically upon failover.
Auto Save on Crash or Rollover
Exception information on 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 file transfer protocol (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.

Show Hardware Commands
The show hardware command tree consists of EXEC Privilege commands used with the MXL Switch.
These commands display information from a hardware sub-component and from hardware-based feature
tables.
Table 39-1 lists the
show hardware commands available as of the latest FTOS version.
Note: Non-management Member units do not support this functionality.
Note: Use the show hardware commands only under the guidance of Dell Force10 Technical Assistance
Center.
