Information Center 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.
Table 1-1 Severity description

errors

notifications

debugging
Information filtering by severity works this way: information with the severity value greater than the
configured threshold is not output during the filtering.
If the threshold is set to 1, only information with the severity being emergencies will be output;
If the threshold is set to 8, information of all severities will be output.
Ten channels and six output directions of system information
The system supports six information output directions, including the Console, Monitor terminal (monitor),
logbuffer, loghost, trapbuffer and SNMP.
