can continue your operation from where you were stopped.
If system information, such as log information, is output before you input any information under the
current command line prompt, the system does not display the command line prompt after the system
information output.
If system information is output when you are inputting some interactive information (non Y/N
confirmation information), the system displays your previous input in a new line but does not display the
command line prompt.
To enable synchronous information output:

Disabling an interface from generating link
up/down logging information
By default, all interfaces generate link up or link down log information when the state changes. In some
cases, you might want to disable specific interfaces from generating this information. For example:
• You are concerned only about the states of some interfaces. In this case, you can use this function
to disable other interfaces from generating link up and link down log information.
• An interface is unstable and continuously outputs log information. In this case, you can disable the
interface from generating link up and link down log information.
Use the default setting in normal cases to avoid affecting interface status monitoring.
To disable an interface from generating link up/down logging information:
