Hi,
I am trying to interpret this statement in Section 8.3.1 Payload Parsing
of RFC 6020.
o If data for a node tagged with "when" is present, and the "when"
condition evaluates to "false", the server MUST reply with an
"unknown-element" error-tag in the rpc-error.
With the context node defined Section 7.19.5. The when Statement
o If the context node represents configuration, the tree is the
data in the NETCONF datastore where the context node exists. The XPath
root node has all top-level configuration data nodes in all modules as
children.
I am providing this dummy module to illustrate my question:
module dummy {
namespace "http://dummy.com";;
prefix "du";
container root {
leaf A {
type empty:
}
leaf B {
when "A";
type uint32;
}
}
}
And I consider the following <edit-config> request, while A & B do not
exist yet in the current datastore.
<rpc message-id="101"
xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
<edit-config>
<target>
<running/>
</target>
<config>
<root xmlns="http://dummy.com";>
<A/>
<B>
3
</B>
</dummy>
</config>
</edit-config>
</rpc>
During the parsing of the payload of the <edit-config>, leaf "A" is not
yet present in the running datastore. The "when" statement that controls
"B" evaluates to false.
Does this mean that the above edit-config request should be rejected
with an "unknown-element" error-tag in the rpc-error? Or am I
misinterpreting the RFC?
Yves
