SNMP Overview
The FWSM provides support for network monitoring using SNMP V1. The FWSM supports traps and
SNMP get requests, but does not support SNMP set requests.
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 Management Information Bases (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, MIB-II compliant browser to receive SNMP traps and browse a MIB.
Table 17-1 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.
