In this video, you’ll learn about the MAC Address Table (also called the CAM table) that exists inside a network switch. The lesson explains how switches use this table to map MAC addresses to specific switch ports, ensuring that frames are forwarded only to the correct destination instead of being broadcast everywhere.

You’ll also see how the MAC table is built dynamically: when a frame enters a switch, the source MAC address is recorded along with the incoming port. Over time, this creates a complete table of connected devices. The video also covers what happens when a switch doesn’t know the destination MAC address—how it floods the frame to all ports until the device is located.

By the end of this video, you will understand how a MAC address table improves efficiency, reduces unnecessary traffic, and forms the foundation of Layer 2 switching, making it an essential concept in networking.
