Hi all!

What are the differences between these two commands? Are these two the same or not? 

Thanks!

Best regards

Hi Rookie R , 

- The major difference between the

Reachability and state ( Default Option )

  command is that of the OverThreshold .

- You can track two aspects of IP SLAs operation: state and reachability. For state, if the return code is OK, the track state is up; if the return code is not OK, the track state is down. For reachability, if the return code is OK or OverThreshold, reachability is up; if not OK, reachability is down.

- While using the Reachability option we can specify a range of threshold and this range will be taken into consideration , in deciding if the reachability is up or down
