The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

OBFL gathers boot, environmental, and critical hardware data for field-replaceable units (FRUs), and stores the information in the nonvolatile memory of the FRU. This information is used for troubleshooting, testing, and diagnosis if a failure or other error occurs, providing improved accuracy in hardware troubleshooting and root cause isolation analysis. Stored OBFL data can be retrieved in the event of a failure and is accessible even if the card does not boot.
Because OBFL is on by default, data is collected and stored as soon as the card is installed. If a problem occurs, the data can provide information about historical environmental conditions, uptime, downtime, errors, and other operating conditions.
The Onboard Failure Logging (OBFL) functionality is enhanced to provide a generic library that can be used by different clients to log string messages.
 Caution |
OBFL is activated by default in all cards. Do not deactivate OBFL without specific reasons, because the OBFL data is used to diagnose and resolve problems in FRUs. |
 Note |
For information about OBFL commands, console logging, alarms, and logging correlation, see Related Documents. |

You must be in a user group associated with a task group that includes the proper task IDs. The command reference guides include the task IDs required for each command. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
OBFL collects and stores both baseline and event- driven information in the nonvolatile memory of each supported card where OBFL is enabled. The data collected includes these:
FRU part serial number
OS version
Boot time
Total run time
Temperature and voltage at boot
Temperature and voltage history
This data is collected in two different ways: as baseline data and event- driven data:
Baseline data is stored independent of hardware or software failures. This includes:
|
Data Type |
Details |
|---|---|
|
Installation |
Chassis serial number and slot number are stored at initial boot. |
|
Temperature |
Information on temperature sensors is recorded after boot. The subsequent recordings are specific to variations based on preset thresholds. |
|
Run-time |
Total run-time is limited to the size of the history buffer used for logging. This is based on the local router clock with logging granularity of 30 minutes. |
OBFL data collection is supported.
FRUs that have sufficient nonvolatile memory available for OBFL data storage support OBFL. For example, the processor supports the OBFL.
