CiscoWorks—Lets you monitor complex internetworks that use Cisco routing devices and helps
you plan, troubleshoot, and analyze your network. CiscoWorks uses the Simple Network
Management Protocol (SNMP) to monitor and control any SNMP device on the network.
CiscoView—A graphical SNMP-based device management tool that provides powerful
real-time views of your 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. CiscoView runs from a centralized network management
site from which you can review, reconfigure, and monitor essential device data from a simple
GUI (that displays information such as dynamic status reports, performance statistics, and
network inquiries) without having to physically check connections for each device, module, or
port at every different or remote location.
