1. Search the forwarding database to determine if the MAC address is listed for any port except port x.2. If the destination MAC address is not found, forward frame out all ports except the one from which is was received.This is part of the learning process described subsequently.3. If the destination address is in the forwarding database for some port y, then determine whether port y is in a blocking or forwarding state. For reasons explained later, a port may sometimes be blocked, which prevents it from receiving or transmitting frames.4. If port y is not blocked, transmit the frame through port y onto the LAN to which that port attaches.
