z To ensure that the device 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 or the
primary/backup switchover.
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:

z 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 device 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.
