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.

can download Cisco MIBs from the following website.

After you download the MIBs, compile them for your NMS.
