470 CHAPTER 22: F ILE SYSTEM MANAGEMENTNote that there is a slash ('/') between module name and severity.5 SeveritySwitch information falls into three categories: log information, debugginginformation and trap information. The info-center classifies every kind of informationinto 8 severity or urgent levels. The log filtering rule is that the system prohibitsoutputting the information whose severity level is greater than the set threshold. Themore urgent the logging packet is, the smaller its severity level. The level representedby “emergencies” is 1, and that represented by ”debugging” is 8. Therefore, whenthe threshold of the severity level is “debugging”, the system will output all theinformation.Definition of severity in logging information is in Table 521.IP IP moduleIPC Inter-process communication moduleIPMC IP multicast moduleL2INF Interface management moduleLACL LANswitch ACL moduleLQOS LANswitch QoS moduleLS Local server moduleMPM Multicast port management moduleNTP Network time protocol modulePPRDT Protocol packet redirection modulePTVL Driver port, VLAN (Port and VLAN) moduleQACL QoS/ACL moduleQOSF Qos profile moduleRDS Radius moduleRM Routing managementRMON Remote monitor moduleRSA Revest, shamir and adleman encryption systemRTPRO Routing protocolSHELL User interfaceSNMP Simple network management protocolSOCKET SocketSSH Secure shell moduleSTP Spanning tree protocol moduleSYSMIB System MIB moduleTELNET Telnet moduleUDPH UDP helper moduleVFS Virtual file system moduleVTY Virtual type terminal moduleWCN Web management moduleXM XModem moduleTable 520 Module Names in Logging InformationModule name Description
