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.
Reconfig Count The number of times the Spanning Tree has been
reconfigured.
Topology Up Time The time since the Spanning Tree was last reconfigured.
