Advanced Configuration

Spanning Tree > STP Status

The STP Status screen describes the STP status on the device.

Spanning Tree > STP Status

Spanning Tree State  Indicates if STP is enabled on the device.

Spanning Tree Mode  Indicates the STP mode by which STP is enabled on the device.

Bridge ID  Identifies the Bridge priority and MAC address.

Designated Root  Indicates the ID of the bridge with the lowest path cost to the instance ID.

Root Port  Indicates the port number that offers the lowest cost path from this bridge to the Root Bridge. It is significant when the Bridge is not the Root. The default is 0.

Root Path Cost  The cost of the path from this bridge to the root.

Root Maximum Age (sec)  Indicates the device Maximum Age Time. The Maximum Age Time indicates the amount of time in seconds a bridge waits before sending configuration messages. The default max age is 20 seconds. The range is 6–40seconds.

Root Hello Time (sec)  Indicates the device Hello Time. The Hello Time indicates the amount of time in seconds a root bridge waits between configuration messages. The default is 2 seconds. The range is 1–10seconds.

Root Forward delay (sec)  Indicates the device forward delay time. The Forward Delay Time indicates the amount of time in seconds a bridge remains in a listening and learning state before forwarding packets. The default is 15 seconds. The range is 4–30seconds.

Topology Changes Counts  Indicates the total amount of STP state changes that have occurred.

Last Topology Change  Indicates the amount of time that has elapsed since the bridge was initialized or reset, and the last topographic change occurred. The time is displayed in a day hour minute second format, for example, 2 days 5 hours 10 minutes and 4 seconds.

Spanning Tree > Global STP

The Global STP screen contains parameters for enabling STP on the device.

Spanning Tree > Global STP

Global Setting

Spanning Tree State  Indicates if STP is enabled on the device.

STP Operation Mode  Indicates the STP mode by which STP is enabled on the device. The possible field values are:

•• Classic STP  Enables Classic STP on the device. This is the default value.

•• Rapid STP  Enables Rapid STP on the device.

•• Multiple STP  Enables Multiple STP on the device.

BPDU Handling  Determines how BPDU packets are managed when STP is disabled on the port/device. BPDUs are used to transmit spanning tree information. The possible field values are:

•• Filtering  Filters BPDU packets when spanning tree is disabled on an interface. This is the default value.

•• Flooding  Floods BPDU packets when spanning tree is disabled on an interface.
