Select which STP tree configuration you want to view.
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.
Port ID
This is the priority and number of the port on the Switch through which this switch
must communicate with the root of the Spanning Tree.
Topology
Changed Times
This is the number of times the spanning tree has been reconfigured.
Time Since Last

This is the time since the spanning tree was last reconfigured.
