This object allows a set of objects to be locked. The lock is only assured by the 'cooperation' of other management entities; they must wait until the lock is cleared (to value zero) prior to setting the lock. When this object is set to a management entity's IP address, if no other management entity has previously set the lock, the set will succeed. Otherwise, an error (BadValue) will be returned. It is the responsibility of the owning management entity to clear the lock when the transactions complete. To protect against a management entity failure during a locked transaction, the agent is NOT responsible for verifying which management entity is performing transactions on locked objects; thus, any management entity can clear this object at any time. The agent does not do anything with this object except disallow multiple sets of different IP addresses (unless the object has been cleared to zero). This means management entities can use this for locking any valid transactions on defined sets of objects. This object can also be used on IPX networks by specifying the low 4 bytes of the station address for the IpAddress.

This object is now obsolete. Individual groups of objects now maintain their own locking mechanisms.
