The traditional approach to building a network has been to follow the hierarchical core- distribution-access layered model. To further enhance the design process, Cisco has created the Network Architectures for the Enterprise. The Cisco Network Architectures for the Enterprise consists of five modules. These modules represent focused views of the Borderless Network, Collaboration, and Data Center/Virtualization architectures. Each module targets a specific segment of the network. Each module consists of a distinct network infrastructure and services. Some network applications extend between the modules. The hierarchical network structure is composed of the access, distribution, and core layers. Each layer has its own functions, which are used to develop a hierarchical network design. The hierarchical model historically was used as the sole method for designing enterprise LAN and WAN data networks. Currently the hierarchical model also serves as a major component for more advanced modular designs.
This course describes a basic network hierarchy and the Cisco modular approach to designing an enterprise network with an emphasis on the Borderless Networks design considerations. The tools administrators require for managing and monitoring the functionality of network devices, connections, and services are also covered.


Introducing the Hierarchical Network Model

  • describe the characteristics of the access layer
  • describe the role and functions of the distribution layer
  • describe the role and functions of the core layer

Using a Modular Approach in Network Design

  • match the modules of the Cisco Network Architectures for the Enterprise to its description
  • describe the enterprise campus infrastructure modules
  • describe the characteristics of the enterprise edge modules
  • describe the characteristics of the enterprise remote modules

Supporting Services on Borderless Networks

  • describe the role of borderless network services in an enterprise network design
  • identify the security design issues within an enterprise network
  • identify mobility considerations within an enterprise network
  • describe application networking service considerations within an enterprise network
  • describe the considerations involved in the provision of high-availability within an enterprise network

Identifying Network Management Protocols and Features

  • describe the features and functions of SNMP
  • identify the basic characteristics of MIBs
  • describe the benefits of using RMON over SNMP
  • describe the basic characteristics of NetFlow
  • describe the primary role of Cisco Discovery Protocol
  • describe the features of syslog
