Module Objectives
- Title: Switching Concepts
- Objective: Explain how Layer 2 switches manage data forwarding.
- Frame Forwarding: Understand the process of frame transmission in networks.
- Switching Domains: Differentiate between collision domains and broadcast domains.
Frame Forwarding Basics
- Ingress and Egress: Ingress refers to data entering an interface, while egress pertains to data exiting it.
- Forwarding decisions are made based on the ingress interface and the destination MAC address.
- Traffic cannot be forwarded out of the interface from which it was received.
The Switch MAC Address Table
- A switch utilizes MAC addresses to determine where to forward frames.
- The MAC address table, or Content Addressable Memory (CAM) table, records source MAC addresses and their corresponding ports.
Learning and Forwarding Process
- Step 1 - Learn: The switch inspects the source address; if absent from the table, the MAC address is added, potentially resetting the timeout period.
- Step 2 - Forward: The switch checks the destination address; if found in the table, it forwards to the specified port; if not found, the frame is flooded to all other interfaces except the one it was received on.
Forwarding Methods
- Switches use application-specific-integrated circuits (ASICs) for rapid decision-making in frame forwarding.
- Different methods may be employed based on the forwarding decisions made by the switch.
