Port States There are only three port states left in RSTP that correspond to the three possible
operational states. The 802.1D disabled, blocking, and listening states are merged into a unique
802.1w discarding state. RSTP only has 3 port states which are discarding, learning and forwarding.
When RSTP has converged there are only 2 port states left:
discarding and forwarding.
