The six settings are independent from each other. The settings will take effect only
after enabling the information center.
Defining the Log Filtering Rules
The SYSLOG classifies the information into eight levels of severity. The log filtering
prevents the system from outputting information whose severity level is greater
than the set threshold. The more urgent the logging packet is, the lower its
severity level. The level for emergencies is 1, and the level for debugging is 8.
Therefore, when the threshold of the severity level is 8, the system will output all
information.
