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.
