Why do we need this?
Need state/status information
Useful information to display to user
Administrative related state is useful in determining the severity of an alarm.
State information such as standby can provide standard way to query or monitor primary & backup hardware
Etc.
Consistency
Currently there are too many different and inconsistent ways to get object state
Recent analyses of 122 notifications in standard MIBs found over 35 state/status objects. There are likely many more.
Providing standard state objects for physical entities is a good start
