Displaying Obfl Information - Cisco Catalyst 3750-E Software Configuration Manual

Chapter 49 Troubleshooting
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-E 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 49-3 Commands for Displaying OBFL Information
Command
show logging onboard [module
[switch-number]] clilog
show logging onboard [module
[switch-number]] environment
show logging onboard [module
[switch-number]] message
show logging onboard [module
[switch-number]] poe
show logging onboard [module
[switch-number]] temperature
show logging onboard [module
[switch-number]] uptime
show logging onboard [module
[switch-number]] voltage

Fan Failures
The fan failures feature is supported only on the Catalyst 3560E-12D switch. You can use this feature to
avoid overheating the switch.
By default, the feature is disabled. When more than one of the fans in a field-replaceable unit (FRU) or
in a power supply fails, the switch does not shut down, and this error message appears:
Multiple fan(FRU/PS) failure detected. System may get overheated. Change fan quickly.
The switch might overheat and shut down.
