Description: Control Nodes can be configured to receive management SCNs 
indicating network updates, including information on 
modification to DDs and DDSs.  This managed object indicates 
if SNMP has access to control node information and, if it 
does, which type of storage nodes can register with the 
server instance as a control node.  Possible values for this 
managed object are: 
  Value              Description 
---------          ---------------- 
anyNode      Any storage node MAY register as a control 
             node 
viewNodes    Specified nodes MAY register as control 
             nodes, SNMP view only 
modifyNodes  Specified nodes MAY register as control 
             nodes, SNMP CAN modify list of nodes 
noSnmpAccess Control node information is not accessible 
             via SNMP 
If only specified nodes are allowed to register as control 
nodes, and SNMP is allowed to modify the list of control 
nodes, then they SHALL be listed in the 
cIsnsCntlNodeIscsiTable and cIsnsCntlNodeFcPortTable. 
If SNMP is not allowed to view or modify the list of control 
nodes, then this managed object SHALL be set to 
noSnmpAccess.
