There are three types of Ethernet addresses.
Unicast address: represents one interface of the local network. The unicast frame is sent to a specific device, not to a group of devices on the local network.
Multicast address: indicates a group of devices on the local network. The frames sent to the multicast address are sent to the device group on the local network.
.
Transfer address: indicates all devices on the local network. Frames sent to the broadcast address are sent to all devices on the local network.
The unicast address has the MAC address of the target device.
Multicast frames have a value of 1 in the low-order bit of the first octet of the destination address. This allows the network switch to distinguish between unicast addresses and multicast addresses. An example of a multicast Ethernet address is 01: 00: 0C: CC: CC: CC, which is the address used by the Cisco Discovery Protocol (CDP).
The broadcast address value is FFFF.FFFF.FFFF (all binary). The switch inundates broadcast frames on all ports except those that have been received ....
