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.
