| 5.4.5 |  | SNMP management applications |

| SNMP is a distributed management protocol. A system can operate exclusively as either an NMS or an agent, or it can perform the functions of both. When a system operates as both an NMS and an agent, another NMS might require that the system query managed devices and provide a summary of the information learned, or that it reports locally-stored management information.

CiscoView is a graphical SNMP-based device management tool that provides real-time views of networked Cisco devices. These views deliver a continuously updated physical picture of device configuration and performance conditions, with simultaneous views available for multiple device sessions. Additionally, CiscoView is designed for integration with leading network management platforms, such as HP OpenView Network Node Manager, to provide seamless and powerful methods of managing Cisco devices such as routers, switches, hubs, concentrators, and adapters.

To start CiscoView from a third party NMS requires that the Integration utility has been installed. Figure illustrates numerous applications available for managing SNMP. Some of these applications may not support SNMPv3. Figure shows SNMP TrapWatcher, a downloadable freeware application that will be used in the following lab activity.
