How do ports on STP-enabled devices move through the different states?
What will be an ideal response?
Ports on STP-enabled devices move through the different states as indicated in the following list:
• From bridge/switch bootup to blocking
• From blocking to listening (or to disabled)
• From listening to learning (or to disabled)
• From learning to forwarding (or to disabled)
• From forwarding to disabled
In a completely configured and stable STP topology, all ports will be in either the forwarding or blocking state. There will only be one root device (bridge or switch) and all other devices will have one designated root port. All of the root ports on each device and all of the ports on the root bridge will be in the forwarding state.
