Recognize a non-recoverable parity error
FTOS generates a message similar to Message 12 when it encounters a real transient parity error.
FTOS also generates an SNMP trap, TR_CHM_SRAM_PARITY_NONRECOVERABLE, at the same
time it generates a console message for non-recoverable parity errors. Use SNMP to poll the number of
non-recoverable errors using the objects chSysCardParityNonrecovrableError.
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
flash:/TRACE_LOG_DIR directory for SW and
HW Traces of the CP and for all Linecards. This directory contains the
TRACE_CURR_BOOT file which
in turn contains the saved trace buffer files.
The
TRACE_LOG_DIR/TRACE_CURR_BOOT files can be reached by FTP or by using the show file
command from the flash://TRACE_LOG_DIR directory.

Note: At reload this directory is renamed to flash:/TRACE_LOG_DIR/TRACE_LAST_BOOT and a new
empty flash:/TRACE_LOG_DIR/TRACE_CURR_BOOT directory is created.
