Auto Save on Crash or Rollover
Exception information on for 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, the TRACE_LOG_DIR
files can be reached by FTP or by using the show file command
from the flash://TRACE_LOG_DIR directory.
On a Standby unit, the TRACE_LOG_DIR
files can be reached only by using the show file command
from the flash://TRACE_LOG_DIR directory.
