Function Description: In the STP Port Setting, one item selection and five
parameters settings are offered for user's setup. User can disable and
enable each port by selecting each Port Status item. User also can set
"Path Cost" and "Priority" of each port by filling in the desired value and
set "Admin Edge Port" and "Admin Point To Point" by selecting the desired
item.
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 sta-
tes. ( 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 LIS-
TENING state) defined in the 802.1d specification are now all rep-
resented as DISCARDING state.
LEARNING state indicates this port can now contribute its lear-
ning knowledge but cannot forward packets still.
FORWARDING state indicates this port can both contribute its
learning knowledge and forward packets normally.
Path Cost Status: It is the contribution value of the path through this
port to Root Bridge. STP algorithm determines a best path to Root
