Configuring the information center

Overview

The information center collects and classifies system information as follows:

Receives system information including log, trap, and debug information from source modules.

Outputs system information to different information channels, according to user-defined output
rules.

Outputs system information to different destinations, based on channel-to-destination associations.

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 is divided into the following types:

Log information—Describes user operations and interface state changes.

Trap information—Describes device faults such as authentication and network failures.

Debug information—Displays device running status for troubleshooting.

Source modules refer to protocol modules, board drivers, and configuration modules which generate
system information. You can classify, filter, and output system information based on source modules. To

view the supported source modules, use the info-center source ? command.

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.
