  1. CCNA 3 Chapter 6Switches By Your Name

  2. Objectives • LAN design • LAN switches

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

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

  5. 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

  6. Layer 1 Design

  7. Typical MDF in Star Topologies

  8. Layer 1 Documentation

  9. Layer 2 Design

  10. LAN Topology

  11. Microsegmentation

  12. Asymmetric Switching

  13. Layer 3 Design

  14. 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.

  15. Physical Network Maps

  16. VLAN Communication

  17. LAN Switches

  18. Access Layer Shared bandwidthSwitched bandwidthMAC layer bandwidthMicrosegmentation

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

  20. Distribution Layer • Aggregation of the wiring-closet connections • Broadcast/multicast domain definition • VLAN routing • Any media transitions that need to occur • Security

  21. Distribution Layer Switches • Catalyst 2926G • Catalyst 5000 family • Catalyst 6000 family

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

  23. Core Layer Switches • Catalyst 6500 series • Catalyst 8500 series • IGX 8400 series • Lightstream 1010
