STP state of the port:
• Blocking - The port is not forwarding Layer 2
traffic but is listening to and forwarding STP
control traffic.
• Disabled - The port is not forwarding any
traffic, including STP control traffic. The port
might be administratively disabled or the
link might be disconnected.
• Forwarding - The port is forwarding Layer 2
traffic.
• Learning - The port is learning the locations
of other devices in the spanning tree before
changing state to forwarding.
• Listening - The port is comparing its own
STP information with information in STP
control packets received by the port to
compute the spanning tree and change
state to blocking or forwarding.
