Overview
Introduction to
Information Center
Acting as the system information hub, information center classifies and manages
system information. Together with the debugging function (the
debugging
command), information center offers a powerful support for network
administrators and developers in monitoring network performance and
diagnosing network problems.
The information center of the system has the following features:
Classification of system information
The system is available with three types of information:
■
Log information
■
Trap information
■
Debugging information
Eight levels of system information
The information is classified into eight levels by severity and can be filtered by
level. More emergent information has a smaller severity level.
Information filtering by severity works this way: information with the severity value
greater than the configured threshold is not output during the filtering.
