Troubleshooting
Configuring OBFL
To enable OBFL, use the hw-module module [switch-number] logging onboard [message level level]
global configuration command. Use the message level level parameter to specify the severity of the
hardware-related messages that the switch generates and stores in the flash memory.
To copy the OBFL data to the local network or a specific file system, use the copy logging onboard
module stack-member destination privileged EXEC command.
We recommend that you do not disable OBFL and that you do not remove the data stored in the flash
Caution
memory.
To disable OBFL, use the no hw-module module [switch-number] 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.
You can enable OBFL by using the hw-module module logging onboard [message level level] global
configuration command.
