Pool members management via SNMP

I'm searching way to manage pool members via SNMP (OID) in F5 LTM 1600. All what I need is enable or disable pool member.

it seems to be read-only. mine is 11.4.0.

ltmPoolMbrStatusEnabledState OBJECT-TYPE 
   SYNTAX INTEGER {
        none(0),
        enabled(1),
     disabled(2),
        disabledbyparent(3)
 }
   MAX-ACCESS read-only
    STATUS current
  DESCRIPTION
     "The activity status of the specified pool member, as specified 
        by the user."
   ::= { ltmPoolMbrStatusEntry 6 } 

this is write-only but deprecated. anyway, i tested but got notWritable error.

ltmPoolMemberNewSessionEnable OBJECT-TYPE 
  SYNTAX INTEGER {
        user-disabled(1),
       user-enabled(2),
        monitor-enabled(3),
     monitor-disabled(4)
 }
   MAX-ACCESS write-only
   STATUS   deprecated
 DESCRIPTION
     "Deprecated!  
       This field is not interested to user through SNMP interface
         Whether a new session can be enabled or not for the specified pool member."
    ::= { ltmPoolMemberEntry 12 }
