snmp MIB error: scalar's parent node must be simple node

I'm trying to create a MIB and have this error, trying to add a "child node" to a parent:

scalar's parent node must be simple node

from simpleweb mib validation

What I'm trying to do is to create parents/childs/elements according to this OID: 1.3.6.1.4.1.1234.1.2.3, I marked the problematic part bold.

Elements "1, 2 and 3" after "1234" have this structure:

myParent1 OBJECT-TYPE
    SYNTAX         Integer32
    UNITS          "test"
    MAX-ACCESS     read-write
    STATUS         current
    DESCRIPTION
        "myParent1"
    DEFVAL { 42 }
::= { myNameOfEnterprise 1 }

myChild2 OBJECT-TYPE
    SYNTAX         Integer32
    UNITS          "test"
    MAX-ACCESS     read-write
    STATUS         current
    DESCRIPTION
        "myChild2"
    DEFVAL { 42 }
::= { myParent1 2 }

But it looks like I can't nest this types, what is simple node and how do I nest it? The elements I try to nest don't have to be of any specific type, its about to understand how the nesting actually works.

The validation error is meant to point out the two types of nodes in a MIB tree, as you've discovered. Think of them as "branches" and "leaves".

  • A branch can hold no value, but may have leaves growing from it. It must be connected to another branch. These are OBJECT IDENTIFIERs.
  • A leaf holds a value, but cannot have any more leaves under it, and must be connected to a branch. These are OBJECT-TYPE.

I guess, I've found a way. Namely to use "OBJECT IDENTIFIER" to group/do nesting.

myParent1    OBJECT IDENTIFIER ::= { myNameOfEnterprise 1 }
myChild2 OBJECT-TYPE
    SYNTAX         Integer32
    UNITS          "test"
    MAX-ACCESS     read-write
    STATUS         current
    DESCRIPTION
        "myChild2"
    DEFVAL { 42 }
::= { myParent1 2 }
