ARAMETERS
The parameters displayed are described in the preceding section, except
for the following items:
•
Bridge ID – A unique identifier for this bridge, consisting of the bridge
priority, the MST Instance ID 0 for the Common Spanning Tree when
spanning tree type is set to MSTP, and MAC address (where the address
is taken from the switch system).
•
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.
