The switch software can be set to use the IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) or the IEEE 802.1s 
Multiple Spanning Tree Protocol (MSTP). If RSTP/MSTP is turned on, you can view the following RSTP bridge 
information for the Spanning Tree Group: 
•  Status of Uplink Fast (upfast) 
•  Current root MAC address 
•  Path-Cost 
•  Port 
•  Hello interval 
•  Maximum age value 
•  Forwarding delay 
•  Aging time 
You can also refer to the following port-specific RSTP information: 
•  Port number and priority 
•  Cost 
•  State 
•  Role 
•  Designated bridge and port 
•  Link type
