                         MSTP Up Count  | 
                     
                         The number of times the MSTP port has been enabled. A Trap is generated on the occurrence of this event.  |

                         MSTP Down Count  | 
                     
                         The number of times the MSTP port has been disabled. A Trap is generated on the occurrence of this event.  | 
                  
| 
                         Region Config Change Count  | 
                     
                         The number of times the switch detects a Region Configuration Identifier Change. The switch generates a trap on the occurrence of this event.  | 
                  
| 
                         Time since topology change  | 
                     
                         The time (in hundredths of a second) since the TcWhile Timer for any port in this Bridge was non-zero for Common Spanning Tree context.  | 
                  
|

                         The count of at least one non zero TcWhile timers on this Bridge for Common Spanning Tree context.  | 
                  
|
