Using On-Board Failure Logging
Beginning in privileged EXEC mode, follow these steps to enable and configure OBFL. Note that OBLF
is enabled by default; you need to enable it only if it has been disabled.
To disable OBFL, use the no hw-module module 1 logging onboard [message level] global
configuration command.
To clear all the OBFL data in the flash memory except for the uptime and CLI command information,
use the clear logging onboard privileged EXEC command.
For more information about the commands in this section, see the command reference for this release.
Displaying OBFL Information
To display the OBFL information, use one or more of the privileged EXEC commands in
Table 35-2

When an OBFL-enabled switch is restarted, there is a 10-minute delay before logging of new data
begins.
