The following illustration shows the actions that occur when a port is in the discarding state.
Learning state
A port in the learning state prepares to participate in frame forwarding. The port enters the learning state from the discarding state. A port will move from learning to forwarding when its forward delay timer expires.
A port in the learning state does the following:
•Discards frames received from the network segment to which it is attached.
•Discards packets sent from another port on the bridge for forwarding.
•Learns station location information from the source address of packets and adds this information to its forwarding database.
•Receives BPDUs for the CPU and transmits BPDUs from the CPU.
