5) Severity
Switch information falls into three categories: log information, debugging information
and trap information. The info-center classifies every kind of information into 8 severity
or urgent levels. The log filtering rule is that the system prohibits outputting the
information whose severity level is greater than the set threshold. The more urgent the
logging packet is, the smaller its severity level is. The level represented by
“emergencies” is 1, and that represented by ”debugging” is 8. Therefore, when the
threshold of the severity level is “debugging”, the system will output all the information.
Definition of severity in logging information is as followed.
Table 4-11 Info-center-defined severity
