3Com Switch 8800 Configuration Guide Chapter 46 System Maintenance and Debugging46-10Switch information falls into three categories: log information, debugging informationand trap information. The info-center classifies every kind of information into 8 severityor urgent levels. The log filtering rule is that the system prohibits outputting theinformation whose severity level is greater than the set threshold. The more urgent thelogging packet is, the smaller its severity level is. The level represented by“emergencies” is 1, and that represented by “debugging” is 8. Therefore, when thethreshold of the severity level is “debugging”, the system will output all the information.Definition of severity in logging information is as followed.Table 46-12 Info-center-defined severitySeverity Value Descriptionemergencies 1 The extremely emergent errorsalerts 2 The errors that need to be corrected immediately.critical 3 Critical errorserrors 4 The errors that need to be concerned but not criticalwarnings 5 Warning, there might exist some kinds of errors.notifications 6 The information should be concerned.informational 7 Common prompting informationdebugging 8 Debugging informationNotice: There is a slash between severity and digest.7) DigestThe digest is abbreviation, it represent the abstract of contents.Notice: There is a colon between digest and content. The digest can be up to 32characters long.46.5.2 Info-center ConfigurationSwitch supports 7 output directions of information.The system assigns a channel in each output direction by default.
