The MAC address table, also known as the Content Addressable Memory (CAM) table, is a table maintained by switches to keep track of the MAC addresses of devices that are connected to the switch ports. The table is used to forward traffic efficiently between devices on the same network.
The two types of information held in the MAC address table are:
A. MAC address - Every device on a network has a unique Media Access Control (MAC) address. The MAC address table contains a list of these addresses, along with the switch port to which each address is connected. When a packet is received on a switch port, the switch examines the MAC address of the source device and updates its MAC address table with this information. The switch then forwards the packet to the appropriate destination port based on the destination MAC address in the packet.
E. Port numbers - The MAC address table also includes the port numbers associated with each MAC address. When a packet is received on a switch port, the switch examines the source MAC address and associates it with the port on which it was received. The switch then adds this information to its MAC address table. When a packet is sent to a specific MAC address, the switch looks up the MAC address in its table and determines the associated port number. The switch then forwards the packet to that port.
C, D and E are not types of information that are held in the MAC address table. The destination IP address and protocols are used by routers to forward packets between different networks, while port numbers are used by transport layer protocols such as TCP and UDP.
