The International Organization for Standardization (ISO) network management model defines five functional areas of network management. This document covers all functional areas. The overall purpose of this document is to provide practical recommendations on each functional area to increase the overall effectiveness of current management tools and practices. It also provides design guidelines for future implementation of network management tools and technologies.

Network Management
The ISO network management model's five functional areas are listed below. • Fault ManagementDetect, isolate, notify, and correct faults encountered in the network. • Configuration ManagementConfiguration aspects of network devices such as configuration file management, inventory management, and software management. • Performance ManagementMonitor and measure various aspects of performance so that overall performance can be maintained at an acceptable level. • Security ManagementProvide access to network devices and corporate resources to authorized individuals.

• Accounting ManagementUsage information of network resources. The following diagram shows a reference architecture that Cisco Systems believes should be the minimal solution for managing a data network. This architecture includes a Cisco CallManager server for those who plan to manage Voice over Internet Protocol (VoIP): The diagram shows how you would integrate the CallManager server into the NMS topology.

The network management architecture includes the following: • Simple Network Management Protocol (SNMP) platform for fault management • Performance monitoring platform for long term performance management and trending • CiscoWorks2000 server for configuration management, syslog collection, and hardware and software inventory management Some SNMP platforms can directly share data with the CiscoWorks2000 server using Common Information Model/eXtensible Markup Language (CIM/XML) methods. CIM is a common data model of an implementation−neutral schema for describing overall management information in a network/enterprise environment. CIM is comprised of a specification and a schema. The specification defines the details for integration with other management models such as SNMP MIBs or Desktop Management Task Force Management Information Files (DMTF MIFs), while the schema provides the actual model descriptions. XML is a markup language used for representing structured data in textual form. A specific goal of XML was to keep most of the descriptive power of SGML whilst removing as much of the complexity as possible. XML is similar in concept to HTML, but whereas HTML is used to convey graphical information about a document, XML is used to represent structured data in a document. Cisco's advanced services customers would also include Cisco's NATkit server for additional proactive monitoring and troubleshooting. The NATkit server would either have a remote disk mount (rmount) or file transfer protocol (FTP) access to the data residing on the CiscoWorks2000 server. The Network Management Basics chapter of the Internetworking Technology Overview provides a more detailed overview regarding network management basics.
