  1. Configure a Switch LAN Switching and Wireless– Chapter 2

  2. Objectives • Summarize the operation of Ethernet as defined for 100/1000 Mbps LANs in the IEEE 802.3 standard. • Explain the functions that enable a switch to forward Ethernet frames in a LAN. • Configure a switch for operation in a network designed to support voice, video, and data transmissions. • Configure basic security on a switch that will operate in a network designed to support voice, video, and data transmissions.

  3. Design Consideration

  4. Controlling Network Latency • Latency caused by network devices • Latency caused by higher OSI layer operations

  5. Switch Forwarding Methods Fast-forwardswitching Fragment-freeswitching
