The Spanning Tree Protocol Administrative Mode associated with the
port or trunk. The possible values are:
• 802.1D - this port participates in the spanning tree and goes through
all of the spanning tree states when the link state transitions from
Down to Up.
• Fast - this port participates in the spanning tree and is put in the
forwarding state when the link state transitions from Down to Up
faster than when STP Mode is 802.1D. In this state, the Forwarding
Delay timer is ignored on Link Up.
• Off - spanning tree is disabled for this port. This is also referred to as
manual spanning tree.
The port's current state as defined by application of the Spanning Tree
Protocol. This state controls what action a port takes on reception of a
frame. If the bridge has detected a port that is malfunctioning it places
that port into the broken state. For ports disabled by Spanning Tree
mode, this object has a value of disabled. The valid values are:
• Disabled
• Blocking
• Listening
• Learning
• Forwarding
• Broken
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.
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
Bridge PDUs.
The Bridge Identifier of the bridge that this port considers to be the
Designated Bridge for this port's segment.
The Port Identifier of the port on the Designated Bridge for this port's
segment.
The number of times this port has transitioned from the Learning state
to the Forwarding state.
The value of the priority field contained in the first (in network byte
order) octet of the (2 octet long) Port ID. The other octet of the Port ID
is given by the value of the Port id. Valid values are from 0 to 255. The
factory default is 128.
Auto (use the STP Port Path Cost parameter) or User Configured.
