Abstract

In one embodiment of the invention, a method and an application tool for dynamically representing configuration commands of a network device on a user interface are provided. According to the method, a data model is stored with the application tool. Thereafter, the configuration commands are rendered on to the data model and the rendered data model is represented on the user interface in real time.

Claims

1. A method for dynamically representing a configuration of a network device on a user interface, the method comprising:

storing a data model, wherein the data model represents a plurality of configuration command lines for the configuration of the network device, the plurality of configuration command lines being organized in configuration command blocks;

detecting that an expand-collapse indicator has been selected for at least one of the configuration command blocks and controlling the representation of the configuration command lines in a hierarchical structure, wherein a selected expand indicator for the at least one configuration command block allows viewing of each configuration command line therein on the user interface, and wherein a selected collapse indicator for the at least one configuration command block allows hiding of each configuration command line therein on the user interface while maintaining each of the hidden configuration commands in the data model;

defining contextual-linkage rules between at least two of the configuration command blocks for the network device using the text editor on the user interface, the defined contextual-linkage rules being stored in a user-editable file that is separate from the data model such that the user editable file containing the defined contextual-linkage rules is specific to a user and persistent for subsequent accesses by the user without changing the data model, wherein the defined contextual-linkage rules allow navigation directly between the at least two of the configuration command blocks on the user interface by designation of source and destination anchors from among the at least two configuration command blocks;

rendering the configuration of the network device by parsing each configuration command, expand-collapse check indicator, and defined contextual-linkage rules from the user-editable file on the data model to provide a dynamically customized view of the configuration of the network device, wherein the dynamically customized view of the configuration of the network device is directly navigable from the source anchor to the destination anchor on the user interface; and

visually representing in textual form, the rendered configuration on a window of the user interface for navigation of the configuration of the network device from the data model,

wherein detection of a pointer over the source anchor in the visual representation produces a snapshot display of all lines of the destination anchor on the user interface proximate to the source anchor.

2. The method of claim 1, further comprising changing the configuration of the network device using the visual representation of the rendered configuration in the textual form.

3. The method of claim 1, further comprising using the data model to allow dynamic navigation of the configuration of the network device using the visual representation of the rendered configuration.

4. The method of claim 1, wherein the rendering the configuration of the network device further comprises linking the source anchor to the destination anchor.

5. The method of claim 4, wherein the linking further comprises parsing the defined contextual-linkage rules to link the source anchor and the destination anchor.

6. The method of claim 5, further comprising dynamically displaying contextual-linkage of configuration command blocks based on the defined contextual-linkage rules and at least one modification to the defined contextual-linkage rules.

7. The method of claim 6, wherein the dynamically displaying further comprises:

accepting a modification to the configuration of the network device from the user interface; and

dynamically designating portions of the modified configuration that matches one of the defined contextual-linkage rules to indicate the contextual-linkage of configuration command blocks.

8. The method of claim 4, further comprising:

displaying the source anchor;

detecting a selected source anchor; and

navigating to the destination anchor linked to the selected source anchor.

9. The method of claim 8, further comprising:

detecting a pointer positioned proximate to one of the defined contextual-linkage rules; and

displaying a snapshot of the destination anchor on the user interface.

10. The method of claim 1, wherein the user-editable file and the data model are stored in a memory on a management station.

11. The method of claim 1, wherein the rendering comprises:

identifying data hierarchy in the data model, the data hierarchy comprising a plurality of levels;

displaying an expand-collapse check indicator at each level in the hierarchy, wherein the expand-collapse check indicator is used for controlling a representation of the data hierarchy; and

detecting a selection of the expand-collapse check indicator.

12. The method of claim 11, further comprising using the expand-collapse check indicator and the data model to navigate the configuration of the network device.

13. The method of claim 11, wherein the rendering further comprises:

identifying a mismatch in a configuration command block, the configuration command block comprising a starting configuration command, an ending configuration command, and one or more body configuration commands; and

indicating the identified mismatch on the user interface.

14. The method of claim 1, wherein the rendering further comprises:

identifying a mismatch in a configuration command block, the configuration command block comprising a starting configuration command, an ending configuration command, and one or more body configuration commands; and

indicating the identified mismatch on the user interface.

15. The method of claim 14, further comprising:

accepting a modification to the configuration command block; and

indicating the identified mismatch for the modified configuration command block, wherein the mismatch is dynamically indicated on the user interface when the modification is accepted.

16. An apparatus for dynamically representing a configuration of a network device, the apparatus comprising:

a processor; and

logic encoded in one or more tangible media for execution by the processor, and when executed operable to;

store a data model, wherein the data model represents a plurality of configuration command lines for the configuration of the network device, the plurality of configuration command lines being organized in configuration command blocks;

detect that an expand-collapse indicator has been selected for at least one of the configuration command blocks and control the representation of the configuration command lines in a hierarchical structure, wherein a selected expand indicator for the at least one configuration command block allows viewing of each configuration command line therein on the user interface, and wherein a selected collapse indicator for the at least one configuration command block allows hiding of each configuration command line therein on the user interface while maintaining each of the hidden configuration commands in the data model;

define contextual-linkage rules between at least two of the configuration command blocks for the network device using the text editor on the user interface, the defined contextual-linkage rules being stored in a user-editable file that is separate from the data model such that the user editable file containing the defined contextual-linkage rules is specific to a user and persistent for subsequent accesses by the user without changing the data model, wherein the defined contextual-linkage rules allow navigation directly between the at least two of the configuration command blocks on the user interface by designation of source and destination anchors from among the at least two configuration command blocks;
