Description (Continued)
Specifies whether a topology change is currently in progress.
Specifies the time (in hundredths of a second) since the last time a
topology change was detected by the Spanning Tree Protocol instance
associated with this service.
Specifies the total number of topology changes detected by the Span-
ning Tree Protocol instance associated with this service since the man-
agement entity was last reset or initialized.
Specifies the bridge identifier of the root of the spanning tree as deter-
mined by the Spanning Tree Protocol instance associated with this ser-
vice. This value is used as the Root Identifier parameter in all
Configuration BPDUs originated by this node.
Specifies the cost of the path to the root bridge as seen from this
bridge.
Specifies how fast the root changes its state when moving toward the
forwarding state.
Specifies the amount of time between the transmission of configura-
tion BPDUs.
Specifies the maximum age of Spanning Tree Protocol information
learned from the network on any port before it is discarded.
This object specifies the priority of the bridge that is currently selected
as root-bridge for the network.
Specifies the port number of the port which offers the lowest cost path
from this bridge to the root bridge.
The ID of the access port where this SAP is defined.
Specifies the type of encapsulation used on BPDUs sent out and
received on this SAP.
Specifies the value of the port number field which is contained in the
least significant 12 bits of the 16-bit port ID associated with this SAP.
Specifies the value of the port priority field which is contained in the
most significant 4 bits of the 16-bit port ID associated with this SAP.
Specifies the contribution of this port to the path cost of paths towards
the spanning tree root which include this port.
Specifies the port identifier of the port on the designated bridge for this
port's segment.
Specifies the bridge identifier of the bridge which this port considers to
be the designated bridge for this port's segment.
