Using On-Board Failure Logging
•Uptime data—Time when a standalone switch or a stack member starts, the reason the switch
restarts, and the length of time the switch has been running since it last restarted
•Voltage—System voltages of a standalone switch or a stack member
You should manually set the system clock or configure it by using Network Time Protocol (NTP).
When the switch is running, you can retrieve the OBFL data by using the show logging onboard
privileged EXEC commands. If the switch fails, contact your Cisco technical support representative to
find out how to retrieve the data.
Configuring OBFL
To enable OBFL, use the hw-module module [switch-number] logging onboard [message level level]
global configuration command. On stacking-capable switches, the range for switch-number is from 1
to 9. On nonstacking-capable switches, the switch number is always 1. 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.
Caution We recommend that you do not disable OBFL and that you do not remove the dat a st ored i n t he f las h
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.
In a switch stack, you can enable OBFL on a standalone switch or on a ll st ack memb er s by usin g the
hw-module module logging onboard [message level level] global configuration 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 Table47-3:
Table47-3 Commands for Displaying OBFL Information
Command Purpose
show logging onboard [module
[switch-number]] clilog Displays the OBFL CLI commands that were entered on a standalone
switch or the specified stack members.
show logging onboard [module
[switch-number]] environment Display the UDI information for a standalone switch or the specified
stack members and for all the connected FRU devices: the PID, the VID,
and the serial number.
show logging onboard [module
[switch-number]] message Display the hardware-related messages generated by a standalone switch
or the specified stack members.
show logging onboard [module
[switch-number]] poe Display the power consumption of PoE ports on a standalone switch or
the specified stack members.
