Command history
The command-history trace feature captures all commands entered by all users of the system with a time
stamp and writes these messages to a dedicated trace log buffer. When the
show command-history
command is entered, the system displays a trace message for each executed command. No password
information is saved to the file. The trace messages are not saved to a file or directory on the internal
system flash.
To view the command-history trace, use the
show command-history command, as shown in Figure 63-16.
Figure 63-16. Command Example: show command-history
Clearing the command history
Clear the command history buffer using the command clear command-history from EXEC Privilege mode,
as shown in Figure 63-17.

Software exception handling on line cards
If a line card CPU experiences a software exception, the system:
• Uploads the contents of the buffered trace logs to persistent memory on the RPM. The files are written
to the TRACE_LOG directory, and they use the naming convention
crash_trace_LPslot#_timestamp.
