Forwarding State
A port in the forwarding state forwards packets. The port enters the forwarding state from the learning
state when the forward delay timer expires.
A port in the forwarding state does the following:
• Forwards packets received from the network segment to which it is attached.
• Forwards packets sent from another port on the switch for forwarding.
• Incorporates station location information into its address database.
• Receives BPDUs and directs them to the system CPU.
• Receives and responds to network management messages.
Disabled State
A port in the disabled state does not participate in frame forwarding or STP. A port in the disabled state
is virtually non-operational.
