Understanding Cisco Configuration Engine Software

The Cisco Configuration Engine is network management software that acts as a configuration service
for automating the of network devices and services (see Figure 5-1). Each Configuration Engine
manages a group of Cisco devices (switches and routers) and the services that they deliver, storing their
configurations and delivering them as needed. The Configuration Engine automates initial
configurations and configuration updates by generating device-specific configuration changes, sending
them to the device, executing the configuration change, and logging the results.
The Configuration Engine supports standalone and server modes and has these CNS components:
Configuration service (web server, file manager, and namespace mapping server)
Event service (event gateway)
Data service directory (data models and schema)
In standalone mode, the Configuration Engine supports an embedded Directory Service. In this mode,
no external directory or other data store is required. In server mode, the Configuration Engine supports
the use of a user-defined external directory.
