Configuring SNMP Chapter 25 Monitoring the Firewall Services Module Severity Levels Table 25-2 lists the syslog message severity levels. Table 25-2 Syslog Message Severity Levels Level Number 0 1 2 3 4 5 6 7 Level Keyword Description emergency System unusable. alert Immediate action needed. critical Critical condition. error Error condition. warning Warning condition. notification Normal but significant condition. informational Informational message only. debugging Appears during debugging only. Note The security appliance does not generate syslog messages with a severity level of 0 (emergency). This level is provided in the logging command for compatibility with the UNIX system log feature, but is not used by the security appliance. Configuring SNMP This section describes how to configure SNMP, but does not provide comprehensive information about all SNMP MIBs and traps. For detailed MIB and event notification information, see Appendix D, "Mapping MIBs to CLI Commands." It includes the following topics: • SNMP Overview, page 25-20 • Enabling SNMP, page 25-32 SNMP Overview The FWSM provides support for network monitoring using SNMP V1 and V2c. The FWSM supports traps and SNMP read access, but does not support SNMP write access. You can configure the FWSM to send traps (event notifications) to a network management station (NMS), or you can use the NMS to browse the MIBs on the FWSM. MIBs are a collection of definitions, and the FWSM maintains a database of values for each definition. Browsing a MIB entails issuing an SNMP get request from the NMS. Use CiscoWorks for Windows or any other SNMP V1 or V2C, MIB-II-compliant browser to receive SNMP traps and browse a MIB. Table 25-3 lists supported MIBs and traps for the FWSM and, in multiple mode, for each context. You can download Cisco MIBs from the following website. http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml After you download the MIBs, compile them for your NMS. 25-20 Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Configuration Guide using ASDM OL-20748-01
