Classification Of System Information; System Information Levels; System Information Channels And Output Destinations - H3C S3100V2-52TP Configuration Manual

NOTE:
By default, the information center is enabled. The information center affects system performance to some
degree due to information classification and output. The impact becomes more obvious when the
information center processes large amounts of information.

Classification of system information

The system information of the information center is categorized into three types:
Log information
•
Trap information
•
• Debugging information

System information levels

The information is classified into eight levels by severity. The severity levels, in descending order are
emergency, alert, critical, error, warning, notice, informational and debug. When system information is
output by level, information with severity level higher than or equal to the specified level is output. For
example, in the output rule, if you configure to output information with severity level being informational,
the information with severity level being emergency through informational will be output.

System information channels and output destinations

The system supports ten channels. By default, channels 0 through 6, and channel 9 are configured with
channel names and output rules, and they are associated with output destinations. The channel names,
output rules and the associations between the channels and output destinations can be changed through
commands. You can configure channels 7, and 8 without changing the default configuration of the eight
channels.
