Hi Siva,

This probably has something to do with efficiency. When a switch receives a portion of the Ethernet frame, it can already make some decisions when it sees the destination MAC address. For example, cut-through switching is a technique where the switch will forward the frame just after reading the destination MAC address, even though it hasn’t received the entire frame yet.
