Spanning Tree
The parameters shown in the following figure and table describe the current bridge STA Information.
Parameter | Description |
Spanning Tree State | Shows if the switch is enabled to participate in an |
| |
Bridge ID | A unique identifier for this bridge, consisting of |
| bridge priority plus MAC address (where the |
| address is normally taken from the agent). |
Max Age | The maximum time (in seconds) a device can wait |
| without receiving a configuration message before |
| attempting to reconfigure. |
Hello Time | The 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., listening to |
| learning to forwarding). |
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 | The number of times the spanning tree has been |
Changes | reconfigured. |
Last Topology | The time since the spanning tree was last |
Change | reconfigured. |
