CNS Configuration Service
The CNS Configuration Service is the core component of the Configuration Registrar. It consists of a
configuration server that works with CNS configuration agents located on the switch. The CNS
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 CNS
Configuration Service when they start up on the network for the first time.
The CNS Configuration Service uses the 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 configuration agent can perform a syntax check on received configuration files and publish events
to indicate 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.
