The first half of a MAC address contains the ID number of the device manufacturer. These IDs are regulated by an Internet standards body. The second half of a MAC address represents the serial number assigned to the device by the manufacturer.
CAM Table
The CAM Table contains a mapping of learned MAC addresses to port and VLANs. The switch checks forwarding requests against the addresses contained in the CAM Table:
•If the MAC address appears in the CAM Table, the packet is forwarded to the appropriate port.
•If the MAC address does not appear in the CAM Table, or the MAC Address mapping has changed, the frame is duplicated and copied to all the ports. Once a reply is received, the CAM table is updated with the new address/VLAN port mapping.
