Setting default operation as replace in the RPC gives "data model already exists" error.

[rosy8]

Hi,

When default-op is "replace", its giving error as below..

<?xml version="1.0" encoding="utf-8"?>
 <rpc-reply xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="13">
  <rpc-error>
    <error-type>application</error-type>
    <error-tag>data-exists</error-tag>
    <error-severity>error</error-severity>
    <error-path>/xxx-config/vrf:vrfs/vrf[name='Test']</error-path>
    <error-message xml:lang="en">Request could not be completed because the relevant data model content already `exists.</error-message>
 </rpc-error>
</rpc-reply>

By looking at the code and log, what I could get that it's trying to do "sr_set_item" before doing "sr_delete_item".

Hi Rosy,
based on this case what you are describing should not happen. So, please provide the initial configuration (also with model would be nice) and the edit-config you are trying to execute.

Hi Michal,

Thanks for responding back.
Below is the rpc request

<?xml version="1.0" encoding="utf-8"?>
<rpc xmlns="urn:ietf:params:xml:ns:netconf:base:1.0" message-id="">
  <edit-config>
   <target>
      <candidate/>
    </target>
    <default-operation>replace</default-operation>
    <config>
     <xxx-config xmlns="http://www.abc.com/ns/xxx-config">
        <vrfs xmlns="http://www.abc.com/ns/xxx-vrf">
          <vrf>
            <name>Test</name>
            <owner-tag/>
            <l3-forwarding>false</l3-forwarding>
            <bgp>true</bgp>
            <domain>default</domain>
          </vrf>
        </vrfs>
      </xxx-config>
    </config>
  </edit-config>
</rpc>

I could not debug it but by looking at the code flow what I am suspecting its hitting the code as mentioned below

        case NP2_EDIT_REPLACE_INNER:
        case NP2_EDIT_CREATE:
            /* create the node, but it must not exists */
            ret = sr_set_item(sessions->srs, path, &value, SR_EDIT_STRICT);

Hi Rosy,
it should be fixed, but for next time a few comments. Look at how I edited your comment and please enclose the code the way I do, what you were doing is fine for one line code, not for blocks. Also, I asked for initial configuration and the model, but you provided neither. I managed to reproduce the issue without this information, but that is not always the case, so please stick to what I ask of you for me to be able to fix issues effectively.

Regards,
Michal

Hi Michal,

Thanks for the fix.
Hey sorry, I misread it and instead of posting initial config I posted the edit-config which we were sending.
Regarding model, it was clearly visible from XML, so that's why did not post it.

Regarding editing, the process which I follow is actually a tedious one which even I donot like to do.
So I will really appreciate if you could let me know how you edit/ what you do when posting a big chunks of code especially if its in the above format . It will be very helpful .

Thanks in advance.

Regards,
Rosy

Hi Rosy,
the simplest way of inserting code probably is simply pasting it, selecting it all, and clicking <> icon from the top tool bar in reply editing window. You will notice it will enclose your code in ```. Optionally, you can specify syntax highlighting by adding the language name after those first ``` such as ```C.
