Threshold Severity Level Description
4 Warning 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.
5
Notification 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:
l The information center receives logs, alarms, and debugging information from all modules.
l The information center outputs information with different severity levels to different
information channels according to the configuration.
l Information 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.
