80 - STP Information
Descriptive information about the STP/RSTP switch port role. Role: Root,
Designated, Alternate, Backup, Disabled, Unknown.
Descriptive information about the STP/RSTP switch port state. State: Blocking,
Listening, Learning, Forwarding, Disabled, Unknown.
The cost of the path to the other bridge from this transmitting bridge at the
specified port. Path cost range is 1 through 200000000.
Decide which port should be blocked by priority in your LAN. Range is 0 through
240 in increments of 16.
Operational link type. Some of the rapid state transactions that are possible
within RSTP are dependent upon whether the port in question can be concerned
to exactly one other bridge (that is, it is served by a point-to-point LAN segment),
or can be connected to two or more bridges (that is, it is served by a shared
medium LAN segment).
Operational edge port state. Present in implementations that support the
identification of edge ports. All ports directly connected to end stations cannot
create bridging loops in the network and can thus directly transition to
forwarding, skipping the listening and learning stages. When the non-bridge
device connects an edge port, this port is in blocking state and turn to forwarding
state in 2*Hello Time seconds. When the bridge device connects an edge port, this
port is a non-edge port automatic.
