Edge Range: Enabled/Disabled, default=Disabled.
State Range : Disabled/ Blocking/ Listening/ Learning/ Forwarding/ Broken
Disabled : For ports which are disabled (see dot1dStpPortEnable), this object will have a
value of disabled.
Blocking : The port will go into a blocking state at the time of selection process, when a
switch receives a BPDU on a port that indicates a better path to the root switch, and if a
port is not a root port or a designated port.
Listening : After blocking state, a root port or a designated port will move to a listening
state. All other ports will remain in a blocked state. During the listening state the port
discards frames received from the attached network segment and it also discards
frames switched from another port for forwarding. At this state, the port receives BPDUs
from the network segment and directs them to the switch system module for processing.
After a forward time delay (The default forward delay time is 15 seconds.), the switch
port moves from the listening state to the learning state.
Learning : A port changes to learning state after listening state. During the learning state,
the port is listening for and processing BPDUs. In the listening state, the port begins to
process user frames and start updating the MAC address table. But the user frames are
not forwarded to the destination. After a forward time delay (The default forward delay
time is 15 seconds), the switch port moves from the learning state to the forwarding
state.
Forwarding : A port in the forwarding state forwards frames across the attached network
segment. In a forwarding state, the port will process BPDUs, update its MAC Address
table with frames that it receives, and forward user traffic through the port. Forwarding
State is the normal state. Data and configuration messages are passed through the
port, when it is in forwarding state.
Broken : If the bridge has detected a port that is malfunctioning it will place that port into
the broken state.
STP Port Range: Enabled/ Disabled, Default is Enabled.
Path Cost Range: 1 ~ 200000000, Default is 20000.
Designated Root The parameter is the unique Bridge Identifier of the Bridge recorded as the Root in the
Configuration BPDUs transmitted by the Designated Bridge for the segment to which the
port is attached.
Format : Root bridge pr Root Bridge MAC address
Designated Cost The parameter is the path cost of the Designated Port of the segment connected to this
port. This value is compared to the Root Path Cost field in received BPDUs.
