The actual operational status of the traffic class. The value
'up(1)' means this traffic class is in use, the value
'down(2)' indicates the traffic class is not in use either due
to an internal problem or because it (or an ancestor) is
administratively disabled, and the value 'downConflict(3)'
indicates the class definition conflicts with those of its
siblings. The value autoClassActive(4) means that the class is
a dynamically created AutoClass, which may not be modified in any
way until it is saved to Non-Volatile configuration memory.
After an AutoClass is saved to NVRAM, it's operational status
will transistion to up(1).
