LABEL DESCRIPTION
Spanning Tree Protocol This field displays Running if STP is activated. Otherwise, it displays Down.
Bridge Root refers to the base of the spanning tree (the root bridge). Our Bridge is this switch.
This switch may also be the root bridge.
Bridge ID This is the unique identifier for this bridge, consisting of bridge priority plus MAC
address. This ID is the same for Root and Our Bridge if the switch is the root switch.
Hello Time (second) This is the time interval (in seconds) at which the root switch transmits a configuration
message. The root bridge determines Hello Time, Max Age and Forwarding Delay
Max Age (second) This is the maximum time (in seconds) a switch can wait without receiving a
configuration message before attempting to reconfigure.
Forwarding Delay
(second) This is the time (in seconds) the root switch will wait before changing states (that is,
listening to learning to forwarding).
Cost to Bridge This is the path cost from the root port on this switch to the root switch.
