Hello 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. All device ports (except  

  designated ports) should receive configuration messages at regular intervals. Any 

  port that ages out STA information (provided in the last configuration message)  

  becomes the designated port for the attached LAN. If it is a root port, a new root 

  port is selected from among the device ports attached to the network.

Fwd Delay: The maximum time (in seconds) the root device will wait before 

  changing states (i.e., discarding to learning to forwarding). This delay is required  

  because every device must receive information about topology changes before it 

  starts to forward frames. In addition, each port needs time to listen for conflicting  

  information that would make it return to a discarding state; otherwise, temporary  

  data loops might result.

Topology: Indicates if Spanning Tree topology is steady or undergoing reconfiguration.  

  (The time required for reconfiguration is extremely short, so no values other than 

  “steady” state are likely to be seen in this field.)

Root ID: The priority and MAC address of the device in the Spanning Tree that this 

  switch has accepted as the root device, and the port connected to the root device. 

 

Port/Group: The number of a port or the ID of a static trunk.

Path Cost: The cost for a packet to travel from this port to the root in the current  

  Spanning Tree configuration. The slower the media, the higher the cost.

Edge Port: Shows if this port is functioning as an edge port, either through manual 

  selection (see the RSTP Port Configuration table) or auto-detection. NOTE: If
