Subject: nested tables
Hi all,
Nested tables are implemented using shared indexes in snmp.
For example, you could define a parent like:
parentTable OBJECT-TYPE
SYNTAX SEQUENCE OF parentEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION "Parent table"
::= { example 1 }
parentEntry OBJECT-TYPE
SYNTAX ParentEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION "Entry in Parent table"
INDEX { parentIndex }
::= { parentTable 1 }
ParentEntry ::= SEQUENCE {
parentIndex Unsigned32,
-- other columns in the table
}
-- define the columns in the parent table
Define a child table as:
childTable OBJECT-TYPE
SYNTAX SEQUENCE OF childEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION "Child table"
::= { example 2 }
childEntry OBJECT-TYPE
SYNTAX ChildEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION "Entry in Child table"
INDEX { parentIndex,
childIndex }
::= { childTable 1 }
ChildEntry ::= SEQUENCE {
childIndex Unsigned32,
-- other columns in the table
}
-- define the columns in the child table
Now the question is when I am implementing the parent and child table in
net-snmp in my subagent, how do I handle the parentIndex in the child table in
my subagent.
Should I still define two indexes for the child table and populated them and
register the indexes in net-snmp or can I reference the parentIndex in the
parent table.
What are the api's I should use.
