Detailed explanation-1: -The Ethernet broadcast address is distinguished by having all of its bits set to 1. As such, its MAC address is the hexadecimal value of FF:FF:FF:FF:FF:FF. This address is used to transmit data to all of the hosts on the local subnet.
Detailed explanation-2: -Broadcast frames-IEEE 802.3 defines the broadcast address as a destination MAC address of FF-FF-FF-FF-FF-FF. Layer 2 control processing-different L2CP frames are needed for specific applications. For example, BPDU packets are needed for STP.
Detailed explanation-3: -A broadcast Ethernet frame will have the broadcast MAC address in the destination address field of the Ethernet header. The broadcast MAC address is FF:FF:FF:FF:FF:FF. A frame with this destination address will be sent to all hosts within a particular network segment/broadcast domain.
Detailed explanation-4: -When the SW receives the frame, it checks the destination MAC address. For a broadcast address FFFF. FFFF. FFFF it will forward the frame to every port except the port in which the switch received the frame.
