FTOS Configuration Guide for the C-Series - Force10 Networks

In the lines above, local7 is the logging facility and debugging is the Syslog level. Therefore the Syslog
daemon sends all messages since debugging is the lowest Syslog level. Refer to logging facility and
logging console command descriptions for more information on those keywords.
To change the severity level of messages logged to a Syslog server, use the following command in the
CONFIGURATION mode:
Command Syntax Command Mode Purpose
logging trap [level] CONFIGURATION Specify the severity level for messages sent to a Syslog
server:
• level range: 0 to 7 or one of the following message
levels (emergencies, alerts, critical, errors, warning,
notifications, informational, or debugging).
The default setting is level 6. To return to the default
setting, enter default logging trap.
To view the logging configuration, use the show running-config logging command (Figure 27) in the
EXEC privilege mode.
FTOS support for software errors—core dumps
Two types of core dumps—application and Kernel—are enabled by default. The High Availability module
is aware of the core dump upload and it does not reboot the crashed RPM until the core dump has
completed or is aborted.
• Kernel core dump—By default the Kernel core dump is sent to the root directory of the internal flash
CP and the CORE_DUMP_DIR directory for RP. The CP kernel core dumps are overwritten every
time there is a new core dump. You should upload kernel core dump manually periodically if you want
to save this information. The RP kernel core dump writes new files until space on the flash is
exhausted, in which case the write is aborted. The kernel core dump is named
f10{cp|rp{1|2}}.kcore.gz.
• Application core dump—On the C-Series and E-Series, the application core dump has the file name
format f10rp1.acore.gz, where is a time stamp, and FTOS
writes it to the internal flash. On the S-series, the file has the name sysd.core.gz, and FTOS sends it to
an FTP server. Since the S-Series uses FTP for application core dumps, you must configure the client
username, password, and server IP address using the command logging coredump server from
CONFIGURATION mode before a software exception occurs.
Note: The Kernel core dump can be large and may take up to 5 to 30 minutes to upload. FTOS does not
overwrite application core dumps so you should delete them as necessary to conserve space on the flash;
if the flash is out of memory, the core dump is aborted. On the S-Series, if the FTP server is not reachable,
the application core dump is aborted.
