Abstract

Apparatus and method for monitoring parameters that govern the operational characteristics of a network device, including the use of templates for generating configuration records of network devices of a selected model type. A database of models is provided, each model representing an associated network device and including attribute values for the parameters of the associated network device. Templates are used to screen a model in order to retrieve values for each of the attributes and create a configuration record. The configuration records may be stored in the configuration manager or other storage device, and/or transferred to the pre-existing model database for use by a network management system in reconfiguring the associated network devices. This system for configuration management is less time consuming, expensive, and error prone than prior systems.

Claims

1. A method for creating a configuration record for a network entity on a computer network, the configuration record having configuration management information for the operation of the network entity, the method including the steps of:

selecting a model type and desired attributes for creating a configuration management template for setting a desired operation of the network entity;

selecting values for the desired attributes to create the configuration record; and

storing the configuration record for at least one model associated with the selected model type.

2. A method as claimed in claim 1, further including the steps of:

comparing actual model attribute values with configuration record attribute values; and

generating an alarm when the comparing step determines the values are not the same.

3. A method as claimed in claim 1, wherein creating a template includes selecting the model type and desired attributes from a pre-existing configuration record.

4. A method as claimed in claim 1, further including:

transferring the configuration record to a user interface; and

displaying the configuration record on the user interface.

5. A method as claimed in claim 1, wherein the step of selecting values for the desired attributes includes using the template to retrieve values for the desired attributes from a model.

6. A method as claimed in claim 1, further including:

transferring the configuration record to the associated model and generating an alarm when the transferring step is unsuccessful.

7. A method as claimed in claim 1, further including:

transferring the configuration record to multiple associated models simultaneously.

8. A method as claimed in claim 1, further including:

verifying the configuration of a device by comparing the attribute values of the associated model and the configuration record.

9. A method as claimed in claim 1, further including:

modifying the parameters of an associated network device to be the same as the attribute values of the configuration record and generating an alarm when the modifying step is unsuccessful.

10. A method as claimed in claim 1, further including:

modifying the parameters of a plurality of associated network devices simultaneously to be the same as the attribute values of the configuration record.

11. A method as claimed in any one of claims 1-10, further including:

maintaining a schedule for initiating one or more of the selecting, comparing, creating, transferring, verifying and modifying steps.

12. A system for creating a configuration record for a network entity on a computer network, the configuration record having configuration management information for the operation of the network entity, the system comprising:

a database of models, each model representing a network entity and including configurable attributes, wherein each model has an associated model type; and

a configuration manager for creating and storing configuration records associated with a plurality of network entities, the configuration manager comprising;

means for creating a configuration management template for setting a desired operation of the network entity by selecting the model type and desired attributes;

means for creating a configuration record by selecting values for desired attributes in the configuration management template; and

means for storing the configuration record for one or more models associated with the selected model type.

13. The system as claimed in claim 12, further including:

means for comparing the actual model attribute values with the configuration attribute values.

14. The system as claimed in claim 13, further including:

means for generating an alarm when the actual model attribute values are not the same as the configuration attribute values.

15. The system as claimed in claim 12, wherein the means for creating a template includes selecting the model type and desired attributes from a pre-existing configuration record.

16. The system as claimed in claim 12, further comprising:

a user interface for displaying the configuration record.

17. The system as claimed in claim 12, wherein the means for storing the configuration record further comprises:

means for transferring the configuration record to the associated model; and

means for generating an alarm when the transferring is unsuccessful.

18. The system as claimed in claim 12, further including:

means for transferring the configuration record to multiple associated models simultaneously.

19. The system as claimed in claim 12, further including:

means for verifying a configuration of a device by comparing the attribute values of the associated model and the configuration record.

20. The system as claimed in claim 12, further including:

means for modifying the parameters of an associated network device to be the same as the attribute values of the configuration record; and

means for generating an alarm when the modifying is unsuccessful.

21. The system as claimed in claim 12, further including:

means for modifying the parameters of a plurality of associated network devices simultaneously to be the same as the attribute values of the configuration record.

22. The system as claimed in any one of 12-21, further including:

means for maintaining a schedule for initiating one or more of the means for selecting, means for comparing, means for creating, means for transferring, means for verifying and means for modifying.
