How to retrieve the interface configuration

[yitung]

How to retrieve the interface configuration??

I saw the "nc-read-xr-ifmgr-cfg-11-ydk.py", the process is just "pass"

def process_interface_configurations(interface_configurations):

    """Process data in interface_configurations object."""

    pass

I tried to modified a bit but I got the response "None".

def process_interface_configurations(interface_configurations):

    """Process data in interface_configurations object."""

    int=interface_configurations.InterfaceConfiguration()

    print ('interface name: ',int.interface_name)

I believe it should be a list of configuration... but don't know how it should be...

any sample can be reference???

Thanks a lot!!

Hey Anton,

Unfortunately, I do not have IOS-XR. I uploaded my sample script at https://github.com/snakeskinsalamander/Netconf-example just in case. It is using an always-on XE on devnet sandbox though. I think it would work, or at least it would be the same concept.

Hey Anton... you can play around with the details of the 'omg' variable used by the filter... but this is as simple as I could make a call to get interface information into an XML output using Python and the ncclient.

#!/usr/bin/env python

import sys

from ncclient import manager

from lxml import etree

if __name__ == '__main__':

    omg = '<interface-configurations xmlns="http://cisco.com/ns/yang/Cisco-IOS-XR-ifmgr-cfg"/>'

    m =  manager.connect(host="my.router.com",

                         port="830",

                         username="me",

                         password="password",

                         device_params={'name':"csr"})

    data = m.get_config("running",'<filter>'+omg+'</filter>')

    print etree.tostring(etree.fromstring(data.xml), pretty_print=True)

I took this right from the #10 example above.

Hi guys thanks a lot for your reply. Sharing with you bgp oper filter which is working for me. It takes just VRF names, networks and route targets from bgp instance. I am using it as "subtree" filter with single tag when I am interesting to get some information from device.Do you happen to know if there is another syntax/functionality for the filtering? I know there is also xpath possibility but seems IOXR doesnt support xpath capability on 6.1.2 version

    filter = '''<bgp xmlns="http://cisco.com/ns/yang/Cisco-IOS-XR-ipv4-bgp-oper">

                <instances>

                <instance>

                <instance-name>default</instance-name>

                <instance-active>

                <vrfs>

                <vrf>

                 <vrf-name/>

                 <afs>

                    <af>

                      <af-name>ipv4-unicast</af-name>

                      <networks>

                        <network>

                          <network/>

                          <local-process-instance-path>

                            <attributes-after-policy-in>

                              <common-attributes>

                                <extended-community/>

                              </common-attributes>

                            </attributes-after-policy-in>

                          </local-process-instance-path>

                        </network>

                      </networks>

                    </af>

                  </afs>

                </vrf>

                </vrfs>

                </instance-active>

                </instance>

                </instances>

                </bgp>

Anton,

When dealing with netconf/yang on IOS-XR, subtree filtering is the only query syntax supported. No timelines for support of XPath filtering at this time, and no other standardised alternative.

Cheers,
