STP Port Configuration
Parameter description:
Port Status:
It displays the current state of a port. We cannot manually set it because it
displays the status only. There are three possible states. ( according to 802.1w
specification)
 DISCARDING state indicates that this port can neither forward packets nor
contribute learning knowledge.
Notice: Three other states (Disable state, BLOCKING state and LISTENING state)
defined in the 802.1d specification are now all represented as DISCARDING state.
 LEARNING state indicates this port can now contribute its learning
knowledge but cannot forward packets still.
 FORWARDING state indicates this port can both contribute its learning
knowledge and forward packets normally.
