A method of provisioning modular network devices is described. A generic configuration is placed on a device; the configuration comprises commands for configuring interfaces associated the device. At the device, each interface associated with the device is configured with at least one command associated with the configuration. The device then attempts to connect with a management point through the current interface. If the current interface can connect to the management point, then an inventory of all interfaces associated with the device is self-initiated and automatically communicated by the device to the management point. In other embodiments, based on the inventory information, a configuration template containing relative interface references may be resolved into a permanent device configuration that includes absolute interface references. As a result, modular network devices in which interfaces of various types are installed at different slot locations may acquire a permanent configuration automatically from a remote management station.

Method and apparatus providing automatic connection announcement from a modular network device to a network management point

A system and an apparatus are disclosed for carrying out automatic network device provisioning and configuration. A configuration service receives a request from a network device to provide configuration information. The configuration service retrieves a template describing the device configuration, where the template associates one symbolic reference to one parameter that may receive values specific to particular devices. Based at least on the symbolic reference and the request, the configuration service retrieves a value of the parameter that is specific to the network device. A device-specific instance of the configuration information is created and stored based at least one the template and the value of the parameter. The configuration information is stored in XML format and conforms to an XML DTD.

Method and apparatus for provisioning network devices using instructions in Extensible Markup Language

A method of provisioning modular network devices is described. A generic configuration is placed on a device; the configuration comprises commands for configuring interfaces associated the device. At the device, each interface associated with the device is configured with at least one command associated with the configuration. The device then connects with a management point through the current interface. An inventory of all interfaces associated with the device is self-initiated and automatically communicated by the device to the management point.

Method and apparatus providing automatic provisioning for modular network devices

A method is disclosed for carrying out network device provisioning and configuration, and communication of other information to a network device, automatically and in an assured manner. A configuration service receives a request from a network device to provide configuration information. The configuration service retrieves a template representing the configuration from a storage location, e.g., a directory service. The configuration service also retrieves one or more parameter values specific to the device. Device-specific values are instantiated for the generic parameters in the template, based on the retrieved values. The resulting configuration is stored in XML format using XML tags to delimit configuration commands, tested for well-formed-ness, and syntax checked. A reliable transport protocol carries the configuration information to the device. At the device, a configuration agent syntax checks the embedded configuration information, and then applies the configuration information to the device. As a result, automatic network provisioning may be accomplished remotely, without requiring a skilled technician to visit customer premises to carry out configuration. The process may be integrated with an event service to enable multiple devices to concurrently receive re-configuration without special synchronization logic.
