“ports” in this section mean “interfaces,” which includes both ports and
trunks.)
Hello Time – Interval (in seconds) at which the root device transmits a
configuration message.
Forward Delay – The maximum time (in seconds) the root device will
wait before changing states (i.e., discarding to learning to forwarding).
This delay is required because every device must receive information
about topology changes before it starts to forward frames. In addition,
each port needs time to listen for conflicting information that would
make it return to a discarding state; otherwise, temporary data loops
might result.
Designated Root – The priority and MAC address of the device in the
Spanning Tree that this switch has accepted as the root device.
Root Port – The number of the port on this switch that is closest to the
root. This switch communicates with the root device through this port.
If there is no root port, then this switch has been accepted as the root
device of the Spanning Tree network.
Root Path Cost – The path cost from the root port on this switch to
the root device.
Configuration Changes – The number of times the Spanning Tree has
been reconfigured.
Last Topology Change – Time since the Spanning Tree was last
reconfigured.
