• MM-MM-MM-SS-SS-SS
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.
