Table-2 (Ethernet frame format)
When the switch receives the frame, it will check the "Source Address" in the Ethernet frame's header. If the address
is not in its Forwarding Table, the switch will learn PC A's MAC and the associated port into its Forwarding Table.
Forwarding Table
Port1 00-20-5C-01-11-11
In addition, when the switch receives the broadcast ARP request, it will flood the frame to all ports except the source
port, port 1 (see Figure -2).
Figure - 2
When the switch floods the frame of ARP requests to the network, all PCs will receive and examine the frame but only
PC B will reply to the query as the destination IP address of PC B matches (see Figure-3).
