State The state of the port. The possible states are as follows:
• Block - The blocking state. A port enters the blocking 
state after CSS initialization. The port does not 
participate in frame forwarding. 
• Listen - The listening state. This state is the first 
transitional state a port enters after the blocking state. 
The port enters this state when STP determines that the 
port should participate in frame forwarding.
• Learn - The learning state. The port enters the learning 
state from the listening state. The port in the learning 
state prepares to participate in frame forwarding.
• Forward - The forwarding state. The port enters the 
forwarding state from the learning state. A port in the 
forwarding state forwards frames. 
• Disabled - The disabled state. A port in the disabled 
state does not participate in frame forwarding or STP. 
A port in the disabled state is nonoperational.
