Chapter 1 Troubleshooting
Using On-Board Failure Logging
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.
In a switch stack, you can enable OBFL on a standalone switch or on all stack members by using the
hw-module module logging onboard [ message level level ] global configuration command.
In a switch stack, if you enter the hw-module module [ switch-number ] logging onboard command on
a stack member that does not support OBFL, such as a Catalyst 3750 switch, a message appears with that
information. If a Catalyst 3750 switch is a stack master in a mixed stack of Catalyst 3750-X and 3750
switches and you enter an OBFL command on the Catalyst 3750 switch, the command does not take
effect on the stack master, but the stack master sends the OBFL configuration information to the stack
members.
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 1-4 :
For more information about using the commands in Table 1-4 and for examples of OBFL data, see the
command reference for this release.
