LABEL DESCRIPTION
BridgeID This field displays the unique identifier for this bridge, consisting of bridge
priority plus MAC address.
TimeSinceTopoChange This field displays the time since the spanning tree was last reconfigured.
TopoChangeCount This field displays the number of times the spanning tree has been
reconfigured.
TopoChange This field indicates whether or not the current topology is stable.
0: The current topology is stable.
1: The current topology is changing.
DesignatedRoot This field displays the unique identifier for the root bridge, consisting of
bridge priority plus MAC address.
RootPathCost This field displays the path cost from the root port on this Switch to the root
switch.
RootPort This field displays the priority and number of the port on the Switch through
which this Switch must communicate with the root of the Spanning Tree.
MaxAge This field displays the maximum time (in seconds) the root switch can wait
without receiving a configuration message before attempting to reconfigure.
HelloTime This field displays the time interval (in seconds) at which the root switch
transmits a configuration message.
ForwardDelay This field displays the time (in seconds) the root switch will wait before
changing states (that is, listening to learning to forwarding).
BridgeMaxAge This field displays the maximum time (in seconds) the Switch can wait
without receiving a configuration message before attempting to reconfigure.
BridgeHelloTime This field displays the time interval (in seconds) at which the Switch
transmits a configuration message.
BridgeForwardDelay This field displays the time (in seconds) the Switch will wait before
changing states (that is, listening to learning to forwarding).
