2.1 Introduction to the Information Center
The information center works as the information hub of a router. It classifies and filters the output
of a system. The information center uses a debugging program to help network administrator
and developers monitor network operation and analyze network faults.
2.2 Information Center Supported by the AR150/200
The information center outputs logs, alarms, and debugging messages at eight severity levels
through 10 information channels.
Information Classification
The information center receives and processes information of the following types:
l Logs
l Debugging information
l Alarms
Severity Levels of Information
Information has eight severity levels as shown in Table 2-1. The lower the severity level, the
more severe the information.
Table 2-1 Description of the severity levels of information
Threshold
Severity Level Description
0 Emergencies A fatal fault, such as a program exception or incorrect
memory usage, occurs on the device. The system must
restart.
1 Alert An important fault, such as the device memory
reaching the highest limit, occurs on the device. The
fault needs to be fixed immediately.
2 Critical A crucial fault, such as the memory or temperature
reaching the lowest limit, or the BFD device being
unreachable, occurs on the device. An internal fault
can also be generated by the device itself. The fault
needs to be analyzed and fixed.
3 Error A fault, such as a user running incorrect commands,
entering a wrong password, or receiving wrong
protocol packets from other devices, occurs on the
device. These faults can be caused by improper
operation or a wrong process.
They do not affect services but should be given
attention.
