Configuration Service
Configuration Service is the core component of Cisco Configuration Engine. It consists of a
configuration server that works with Cisco IOS CNS agents on the switch. Configuration Service
delivers device and service configurations to the switch for initial configuration and mass
reconfiguration by logical groups. Switches receive their initial configuration from the Configuration
Service when they start up on the network for the first time.
Configuration Service uses CNS Event Service to send and receive configuration change events and to
send success and failure notifications.
The configuration server is a web server that uses configuration templates and the device-specific
configuration information stored in the embedded (standalone mode) or remote (server mode) directory.
Configuration templates are text files containing static configuration information in the form of CLI
commands. In the templates, variables are specified using Lightweight Directory Access Protocol
(LDAP) URLs that reference the device-specific configuration information stored in a directory.
The Cisco IOS agent can perform a syntax check on received configuration files and publish events to
show the success or failure of the syntax check. The configuration agent can either apply configurations
immediately or delay the application until receipt of a synchronization event from the configuration
server.
Event Service
Cisco Configuration Engine uses Event Service for receipt and generation of configuration events. The
event agent is on the switch and facilitates the communication between the switch and the event gateway
on Configuration Engine.
