1.1 Information Center Overview
1.1.1 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:
I. Classification of system information
The system is available with three types of information:
z Log information
z Trap information
z Debugging information
II. 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.
