2 Information Center Configuration
About This Chapter
This chapter describes how to configure the information center to control the output of logs,
alarms, and debugging messages.
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.
2.3 Enabling Log Output
This section describes how to output logs of a specific module to a log file, console, terminal,
or log host.
2.4 Enabling Alarm Output
This section describes how to configure a specific module to output alarm information to log
files, consoles, terminals, or SNMP agents.
2.5 Enabling the Output of Debugging Information
This section describes how to configure a specific module to output debugging information to
log files, consoles, terminals, or SNMP agents.
2.6 Maintaining Information Center
This section describes how to run the following commands to delete messages in the buffer of
the information center. Note that deleted messages cannot be restored.
2.7 Information Center Configuration Examples
This section provides information center configuration examples.

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:
lLogs
lDebugging information
lAlarms
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
0Emergencies 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.

Threshold Severity Level Description
4Warning An abnormal situation, such as the user disabling the
routing process, the BFD detecting packet loss, or the
wrong protocol packet being received occurs on the
device.
The fault may affect services and should be given
attention.
5Notification Indicates the key operations used to ensure that the
device runs normally, such as the execution of the
shutdown command, the performance of neighbor
discovery, or the status change of the state machine.
6 Informational Indicates the common operations used to ensure that
the device runs normally, such as the execution of the
display command.
7 Debugging Indicates that the common device information does
not require attention.
When information filtering based on severity levels is enabled, only the information whose
severity level threshold is less than or equal to the configured value is output.
For example, if the severity level value is configured to 6, only information with a severity level
ranging from 0 to 6 is output.
Working Process of the Information Center
The working process of the information center is as follows:
lThe information center receives logs, alarms, and debugging information from all modules.
lThe information center outputs information with different severity levels to different
information channels according to the configuration.
lInformation is transmitted in different directions based on the relationship between the
information channel and the output direction.
Generally, the information center distributes three types of information classified into eight
levels to 10 information channels. Information is then output to different directions.
As shown in Figure 2-1, logs, alarms, and debugging information have default output channels.
They can be customized to be output from other channels. For example, logs can be configured
to be output to the log cache through Channel 6 rather than the default Channel 4.

Information Channels and Output Directions
The system supports 10 channels. The first six channels (Channel 0 to Channel 5) have default
channel names and are associated with six default output directions. For devices equipped with
storage media, log information is output to log files through Channel 9 by default. That is, seven
total default output directions are supported.
For details of the association relationship between default channels and output directions, see
Table 2-2.

8 Unspecified Unspecified Reserved, this channel can be configured to
output to different directions.
9 Channel9 Log file Outputs information to log files that can
receive logs, traps, and debugging
information. Information is saved to the
USB disk in the file format.
In the case of multiple log hosts, logs can be output through one channel or several channels.
For example, some logs can be output to a log host through Channel 2 (loghost) and some logs
can be output to another log host through Channel 6. For easy management, the name of Channel
6 can be changed.
Format of Logs
Syslog is a sub-function of the information center. It outputs information to a log host through
port 514.
Figure 2-2 shows the format of logs.
