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.
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, you can reach the TRACE_LOG_DIR
files by file transfer protocol (FTP) or by using
the
show file command from the flash://TRACE_LOG_DIR directory.
Hardware watchdog timer
The hardware watchdog command automatically reboots an FTOS switch/router when a unit is
unresponsive. This is a last resort mechanism intended to prevent a manual power cycle.
Environmental monitoring
The S6000 supports environmental monitoring to detect transmit power readings, receive power readings,
and temperature updates. To receive periodic RX/TX power and temperature updates, use the
enable
optic-info-update interval
command in Config mode.
FTOS (Conf) # enable optic-info-update interval?
<120-6000> Polling interval in seconds (default = 300)
Note: Non-management member units do not support this functionality.
