  1. CCNA 3 v3.0 Module 5 Switches

  2. Purpose of This PowerPoint • This PowerPoint primarily consists of the Target Indicators (TIs) of this module in CCNA version 3.0. • It was created to give instructors a PowerPoint to take and modify as their own. • This PowerPoint is: • NOT a study guide for the module final assessment. • NOT a study guide for the CCNA certification exam. • Please report any mistakes you find in this PowerPoint by using the Academy Connection Help link.

  3. To Locate Instructional Resource Materials on Academy Connection: • Go to the Community FTP Center to locate materials created by the instructor community • Go to the Tools section • Go to the Alpha Preview section • Go to the Community link under Resources • See the resources available on the Class home page for classes you are offering • Search http://www.cisco.com • Contact your parent academy!

  4. Objectives • LAN design • LAN switches

  5. LAN Design Goals • Functionality • Scalability • Adaptability • Manageability

  6. LAN Design Considerations • The function and placement of servers • Collision-detection issues • Segmentation issues • Broadcast domain issues

  7. LAN Design Methodology • Gather requirements and expectations • Analyze requirements and data • Design the Layer 1, 2, and 3 LAN structure, or topology  • Document the logical and physical network implementation

  8. Layer 1 Design

  9. Typical MDF in Star Topology

  10. Extended Star Topology in a Multi-Building Campus

  11. Layer 1 Documentation Logical Diagram

  12. Cut Sheet

  13. Layer 2 Design: Developing a LAN Topology

  14. Microsegmentation of the Network

  15. Asymmetric Switching

  16. Layer 2 Switch Collision Domains

  17. Layer 3 Design

  18. Use Routers to Impose Logical Structure Routers provide scalability because they serve as firewalls for broadcasts. They can also provide scalability by dividing networks into subnetworks, or subnets, based on Layer 3 addresses.

  19. Physical Network Maps

  20. Setting Up VLAN Implementation

  21. VLAN Communication

  22. Access Layer

  23. Access Layer • Functions of the Access Layer: • Shared Bandwidth • Switched Bandwidth • MAC Layer Bandwidth • Microsegmentation

  24. Access Layer Switches • Catalyst 1900 series • Catalyst 2820 series • Catalyst 2950 series • Catalyst 4000 series • Catalyst 5000 series

  25. Distribution Layer

  26. Distribution Layer • In a switched network, the distribution layer includes several functions such as the following: • Aggregation of the wiring-closet connections • Broadcast/multicast domain definition • VLAN routing • Any media transitions that need to occur • Security

  27. Cisco Catalyst 2926G Cisco Catalyst 6000 Family Distribution Layer Switches <not pictured> Cisco Catalyst 5000 Family

  28. Core Layer The core layer is a high-speed switching backbone. The core layer should be designed to switch packets as fast as possible.
