System Information Types; Eight Levels Of System Information; Output Destinations And Channels Of System Information - HP 5820X Switch Configuration Manual

NOTE:
By default, the information center is enabled. An enabled information center affects the system
performance in some degree due to information classification and output. Such impact becomes more
obvious in the event that there is enormous information waiting for processing.

System information types

The system information of the information center falls into the following types:
• Log information
• Trap information
• Debugging information

Eight levels of system information

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

Output destinations and channels of system information

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