Automatic trace log updates
The system automatically saves software trace files to the internal flash. The files are saved to the
TRACE_LOG_DIR directory on the flash, and are named so that they can be viewed in a logical order. The
first automatic trace file is labeled
sw_trace_RPM0CP.0. Up to five trace logs are saved before the system
begins overwriting them (sw_trace_RPM0CP.1, and so on until sw_trace_RPM0CP.4).
Trace file
sw_trace_RPM0CP.0 is not overwritten so that chassis bootup message are preserved.
The trace file names are:
• CP [SW trace] :
• sw_trace_RPM[0|1]CP.0, sw_trace_RPM[0|1]CP.1, sw_trace_RPM[0|1]CP.2,
sw_trace_RPM[0|1]CP.3 and sw_trace_RPM[0|1]CP.4
• LP [SW trace] :
• sw_trace_LP[0-13].0, sw_trace_LP[0-13].1, sw_trace_LP[0-13].2, sw_trace_LP[0-13].3 and
sw_trace_LP[0-13].4
Trace files are saved in the internal flash:/TRACE_LOG_DIR/TRACE_CURR_BOOT. Upon a system
reload this directory is renamed flash:/TRACE_LOG_DIR/TRACE_LAST_BOOT, and a fresh empty
flash:/TRACE_LOG_DIR/TRACE_CURR_BOOT directory is created.
Save a trace log to a file on the flash
The trace logs are saved automatically but you can save the contents of a buffer manually with the CLI.
The files are named the same whether they are saved automatically or manually.
To manually write the contents of a trace log on CP to a file on the flash:
To manually write the contents of a trace buffer on RP or LP to a file on the flash:
Manual reload messages
When the chassis is reloaded manually (through the CLI), trace messages in all of the buffers (software and
hardware) in the CP and line cards are saved to the flash as
reload_traceRPM0_CP and reload_traceLP1 in
flash:/TRACE_LOG_DIR/TRACE_CURR_BOOT. After reload, you can see these files in flash:/
TRACE_LOG_DIR/TRACE_LAST_BOOT.
