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.
Event Service is a highly capable publish-and-subscribe communication method. Event Service uses subject-based
addressing to send messages to their destinations. Subject-based addressing conventions define a simple, uniform
namespace for messages and their destinations.
