dot1dStpPortTable

1.3.6.1.2.1.17.2.15.1.1

dot1dStpPort

Integer32{(1,65535)}

read-only

The port number of the port for which this entry

contains Spanning Tree Protocol management information.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.17.2.15.1.2

dot1dStpPortPriority

Integer32{(0,255)}

read-write

The value of the priority field that is 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 dot1dStpPort.

On bridges supporting IEEE 802.1t or IEEE 802.1w,

permissible values are 0-240, in steps of 16.

The actually supported access is read-only.

1.3.6.1.2.1.17.2.15.1.3

dot1dStpPortState

INTEGER{disabled(1),blocking(2),listening(3),learning(4),forwarding(5),broken(6)}

read-only

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

will place that port into the broken(6) state. For

ports that are disabled (see dot1dStpPortEnable), this

object will have a value of disabled(1).

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.17.2.15.1.4

dot1dStpPortEnable

INTEGER{enabled(1),disabled(2)}

read-write

The enabled/disabled status of the port.

The actually supported access is read-only.

1.3.6.1.2.1.17.2.15.1.5

dot1dStpPortPathCost

Integer32{(1,65535)}

read-write

The contribution of this port to the path cost of

paths towards the spanning tree root which include

this port. 802.1D-1998 recommends that the default

value of this parameter be in inverse proportion to

the speed of the attached LAN.

New implementations should support dot1dStpPortPathCost32.

If the port path costs exceeds the maximum value of this

object then this object should report the maximum value,

namely 65535. Applications should try to read the

dot1dStpPortPathCost32 object if this object reports

the maximum value.

The actually supported access is read-only.

1.3.6.1.2.1.17.2.15.1.6

dot1dStpPortDesignatedRoot

OCTET STRING{(8,8)}

read-only

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.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.17.2.15.1.7

dot1dStpPortDesignatedCost

Integer32

read-only

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.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.17.2.15.1.8

dot1dStpPortDesignatedBridge

OCTET STRING{(8,8)}

read-only

The Bridge Identifier of the bridge that this

port considers to be the Designated Bridge for

this port's segment.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.17.2.15.1.9

dot1dStpPortDesignatedPort

OCTET STRING{(2,2)}

read-only

The Port Identifier of the port on the Designated

Bridge for this port's segment.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.17.2.15.1.10

dot1dStpPortForwardTransitions

Counter32

read-only

The number of times this port has transitioned

from the Learning state to the Forwarding state.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.17.2.15.1.11

dot1dStpPortPathCost32

Integer32{(1,200000000)}

read-write

The contribution of this port to the path cost of

paths towards the spanning tree root which include

this port. 802.1D-1998 recommends that the default

value of this parameter be in inverse proportion to

the speed of the attached LAN.

This object replaces dot1dStpPortPathCost to support

IEEE 802.1t.

The actually supported access is read-only.
