SPANNING TREE PROTOCOL CONFIGURATION

Spanning Tree Protocol Configuration

The Spanning Tree Algorithm (STA) detects and disable network loops and provides backup links between switches, bridges, and routers to ensure that only one route exists between any two stations on the network. The backup links automatically take over when a primary link goes down.

Managing Global Settings

Global setting apply to the entire switch.

Fields and Attributes

The following global attributes are read-only and cannot be changed:

•Bridge ID – The priority and MAC address of this device.

•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 – The time since the Spanning Tree was last reconfigured.

•Hold Time – The minimum interval between the transmission of consecutive Configuration BPDUs. (CLI only.)

The following global attributes can be configured:

•Spanning Tree State – Enable/disable this switch to participate in an STA-compliant network.
