z
To ensure that the AC works normally, use the info-center logfile size-quota command to set a
logfile to be no smaller than 1 MB and no larger than 10 MB.
z
Use the info-center logfile switch-directory command to manually configure the directory to
which a log file can be saved. The configuration will be invalid after system reboot.
Configuring Synchronous Information Output
Synchronous information output refers to the feature that if the user’s input is interrupted by system
output such as log, trap, or debugging information, then after the completion of system output the
system will display a command line prompt (a prompt in command editing mode, or a [Y/N] string in
interaction mode) and your input so far.
This command is used in the case that your input is interrupted by a large amount of system output.
With this feature enabled, you can continue your operations from where you were stopped.
Follow these steps to enable synchronous information output:

If system information, such as log information, is output before you input any information under the
current command line prompt, the system will not display the command line prompt after the
system information output.
z
If system information is output when you are inputting some interactive information (non Y/N
confirmation information), then after the system information output, the system will not display the
command line prompt but your previous input in a new line.
Disabling a Port from Generating Link Up/Down Logging Information
By default, all the ports of the AC generate link up/down logging information when the port state
changes. Therefore, you may need to use this function in some cases, for example:
z
You only concern the states of some of the ports. In this case, you can use this function to disable
the other ports from generating link up/down logging information.
z
The state of a port is not stable, and therefore redundant logging information will be generated. In
this case, you can use this function to disable the port from generating link up/down logging
information.
Follow the steps below to disable a port from generating link up/down logging information:
