Trace Logs; Buffer Full Condition - Dell Force10 C150 Configuration Manual

Trace logs

In addition to the syslog buffer, 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.
Some trace files are automatically saved and stored in the
HW Traces of the CP and for all Linecards. This directory contains the

Buffer full condition

When the Trace Ring Buffer fills up, trace logs are saved into the flash so the buffer can be clear for further
trace activity. The saved file is named hw_trace_RPM0CP.0, for example. If the buffer fills a second time,
a second file is created as hw_trace_RPM0CP.1 and saved to the flash. Following the fifth file created
(hw_trace_RPM0CP.4), the saved files are overwritten starting with the .1 version (hw_trace_RPM0CP.1).
These files will be saved in
renamed as
TRACE_CURR_BOOT
Trace file hw_trace_RPM0CP.0 is not overwritten so that chassis bootup message are preserved.
The CP and LP trace file names are:
Note: Line card 1 is taken as the example for the following filenames.
• CP [SW trace] : sw_trace_RPM0CP.0, sw_trace_RPM0CP.1, sw_trace_RPM0CP.2,
sw_trace_RPM0CP.3 and sw_trace_RPM0CP.4
• CP [HW trace] : hw_trace_RPM0CP.0, hw_trace_RPM0CP.1, hw_trace_RPM0CP.2,
hw_trace_RPM0CP.3 and hw_trace_RPM0CP.4
• LP [SW trace] : sw_trace_LPX.0, sw_trace_LP1.1, sw_trace_LP1.2, sw_trace_LP1.3 and
