Figure 25 Information center diagram
By default, the information center is enabled. It affects system performance to some degree when
processing large amounts of information. If the system resources are insufficient, disable the information
center to save resources.
Classification of system information
System information falls into the following types:
• Log information
• Trap information
• Debugging information
System information levels
System information is classified into eight severity levels, from 0 through 7 in descending order. The
device outputs the system information with a severity level that is higher than or equal to the specified
level. For example, if you configure an output rule with a severity level of 6 (informational), information
that has a severity level from 0 to 6 is output.
