A method is provided to dynamically manage the configuration of a network device. An application supporting a protocol, network interface or other component of the configuration operates in conjunction with a master agent and subagent to send and receive configuration management information. The application further operates in conjunction with a configuration manager interface and configuration manager to access and update the configuration in accordance with a priority of the application, and without taking the network device out of service.

Method and apparatus for dynamic configuration management

A method and apparatus is provided to restore the configuration of a network device. A configuration manager in a network device saves a version of the configuration of the network device by storing the configuration data in an format that conforms to a standard markup language such as the extended markup language (XML). The format includes a sequence of corresponding tags and values that represent the content of the internal data structures in the memory of the router that comprise the saved version of the configuration. At the time of restoration, an parser is used to parse the values from the tags and the configuration manager restores the contents of the internal data structures in the memory of the router to the parsed values in accordance with the corresponding tags.

A method is provided to convert network management protocol request into a markup language representation. In one embodiment, the present invention includes receiving a network management protocol request at a network device, generating a plurality of markup language tags and content embedded in the markup language tags based on the received request, and responding to the request using the plurality of markup language tags and content embedded in the markup language tags using a unified backend interface. In one embodiment, routines used to generate the plurality of markup language tags and content are generated automatically using an instrumentation module.

A layer-2 network switch device forwarding database implementation and method to access the forwarding database. A forwarding database (FDB) is implemented as a tree. A separate VLAN database is also structured as a tree. Each node in the tree represents a separate VLAN. For each VLAN, all associated ports are maintained in a data structure organized as a tree. Likewise, all port information is maintained in a tree-based data structure, and for each port, all VLAN information associated with the port is maintained in a tree data structure. Each node in a VLAN's port tree data structure is linked with each corresponding node in the port's VLAN tree data structure. Each pair of nodes maintains a linked list of all FDB entries relating to the node pair. Operations are quickly and efficiently performed on the FDB using the data structure architecture.

Forwarding database in a network switch device

A computing system receives a compressed archive file that includes a one or more new executable software modules, and a installation file specifying instructions for installing such modules on the computing system. The modules and the installation file are extracted from the compressed archive file, and the modules installed in accordance with the instructions. Instances of executing software modules that correspond to the installed modules are notified about their impending termination. The instances are then terminated before launching corresponding instances of the installed modules.

Method and apparatus for modifying software

A method and system for a scriptable command line interface is described. A script is written and associated with each command. When an input is received at a command line interface, the input is parsed to identify a command and any associated parameters. The script associated with the command is invoked, and parameters associated with the command are sent to an application to configure the application in accordance with the script. The application is executed and data is generated. The script receives the data from the application and formats the data for output.
