  1. Will ncclient support the operation? This pull request has not been merged:
    Initial support for RFC8526: NETCONF Extensions for NMDA #450

  2. Need know the right way to use "with_defaults".

Below is the way I used "with_defaults". It works but is a little slow. Not sure if this is the right way use this XML-encoded parameter.

conn = manager.connect(
    host=***,
    username=***,
    password=***,
    hostkey_verify=False,
)

SYS_sub = """<filter xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
                            <packs xmlns="http://***"></packs>
                       </filter>"""
conn.get(filter=SYS_sub, with_defaults="report-all")

And I would like to know why this does not work (cannot access the default values):

SYS_sub = """<packs xmlns="http://***"></packs>"""
conn.get(filter=("subtree", SYS_sub), with_defaults="report-all")

Thank you!

@fourwilling:

  1. If the author of the PR brings it up to date with the main line it will likely be adopted. This is why the tag "Waiting" has been applied.
  2. ncclient adds the <filter> tag,and so you should not have it as part of your filter definition.
  3. The performance of with-defaults typically depends on the device being queried.

Do you mean I should not have <filter> in SYS_sub? This is actually the only way that works for me thus far.

 SYS_sub = """<filter xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
                             <packs xmlns="http://***"></packs>
                        </filter>"""
 conn.get(filter=SYS_sub, with_defaults="report-all")

@fourwilling, I mixed some things up before, my apologies. ncclient adds the <filter> tag when using the filter=("subtree", SYS_sub) variant, and I see now that you used that correctly.

In the last example you give, does your device honour the with_defaults setting?
