The object is to control the position of an ACE in the ACL. Specifies the order position of a new ACE before a ACE which is already in the ACL. It means that the new ACE will replace the position of the ACE which the object specifies. For example, if there are 6 ACEs in an ACL, so the positions of those 6 ACEs will be 1, 2, 3, 4, 5, 6. If the user would like to add a new ACE and he specifies 4 to be the value of this object, the old ACEs in positions, 4, 5, 6 will become 5, 6, 7 while the entry containing the new ACE is active. The removing is similar. Be careful, for example, if the user would like to move an ACE whose position is 2 to before the ACE whose position is 5. He put the status of that entry to in-active and the position order will be 1, 2, 3, 4, 5. The old ACEs in positions 3, 4, 5, 6 becomes 2, 3, 4, 5. So, the user has to specify the object to 4, because the ACE in old position 5 has been moved to position 4. If not specified, the default value 0 will be used. And the new ACE is appended to the end of the ACL. 0 will be always returned if the status of this row is active. If the entry is from active to notInService, this object should has default value.
