Controls creation/deletion of entries in this table. Only the values
'createAndGo' ,'destroy', 'active' and 'notInService' may be SET.
The SNMP manager would set the row status to notInService before making
any VC class attribute changes explained in juniAtmVcClassTable. Once the
VC class attribute changes are complete, the SNMP manager would set the
row status to active, upon which the VC class attribute changes would
be committed. Any ATM VC class attribute changes that are made when the
row status is 'active' are committed right away.
