Question
What type of frames does a Layer 2 switch look up the MAC address table for A. IPv4 frames B. IPv6 frames C. Ethernet frames D. Collision domain frames
Solution
A Layer 2 switch looks up the MAC address table for C. Ethernet frames.
Here's a step-by-step explanation:
-
When a frame arrives at a switch, the switch examines the MAC address of the device that sent the frame, also known as the source MAC address.
-
The switch then looks up this MAC address in its MAC address table. This table is a type of memory that stores a list of all the MAC addresses of all the devices connected to each of its ports.
-
If the switch finds the source MAC address in its table, it knows which port the device is connected to. If it doesn't find the source MAC address, it adds it to the table.
