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.
