Parameter Description

Priority

Device priority is used in selecting the root device, root port, and designated port. The

device with the highest priority becomes the STA root device. However, if all devices

have the same priority, the device with the lowest MAC address will then become the

root device.

Hello Time

The time interval (in seconds) at which the root device transmits a configuration

message.

Max Age

The maximum time (in seconds) a device can wait without receiving a configuration

message before attempting to reconfigure.

Forward Delay

The maximum time (in seconds) the root device will wait before changing states (i.e.,

listening to learning to forwarding).

Hold Time

The minimum interval between the transmission of consecutive Configuration BPDUs

Designated Root The priority and MAC address of the device in the Spanning Tree that this switch has

accepted as the root device.

Root Cost

The path cost from the root port on this switch to 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.

Configuration

Changes

The number of times the Spanning Tree has been reconfigured.
