Chapter 2 Catalyst 3750-X and 3560-X Switch Cisco IOS Commands
hw-module
hw-module
Use the hw-module global configuration command on the switch stack or on a standalone switch to
enable on-board failure logging (OBFL). Use the no form of this command to disable this feature.
hw-module module [switch-number] logging onboard [message level level]
no hw-module module [switch-number] logging onboard [message level]
Syntax Description
Defaults OBFL is enabled, and all messages appear.
Command Modes Global configuration
Command History
Usage Guidelines We recommend that you keep OBFL enabled and do not erase the data stored in the flash memory.
To ensure that the time stamps in the OBFL data logs are accurate, you should manually set the system
clock, or configure it by using Network Time Protocol (NTP).
If you do not enter the message level level parameter, all the hardware-related messages generated by
the switch are stored in the flash memory.
On a standalone switch, entering the hw-module module [switch-number] logging onboard [message
level level] command is the same as entering the hw-module module logging onboard [message level
level] command.
Entering the hw-module module logging onboard [message level level] on a stack master enables
OBFL on all the stack members that support OBFL.
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 or
Catalyst
3750-X and 3750 switches and you enter an OBFL command on the Catalyst 3750 switch, the
command does not take affect on the stack master, but the stack master sends the OBFL configuration to
the stack members.
switch-number (Optional) On Catalyst 3750-X switches, specify the switch number, which is the
stack member number. If the switch is a standalone switch, the switch number is 1.
If the switch is in a stack, the range is 1 to 9, depending on the switch member
numbers in the stack.
On Catalyst 3560-X switches, the switch number is always 1.
message level
level
(Optional) Specify the severity of the hardware-related messages that are stored in
the flash memory. The range is from 1 to 7.
