Trying to ping do a simple ping ont a Cisco NCS540 IOSXR 7.6.2 , eventually pings from vrf as well, but for now I want to get this working.

 

I'm using the dispatch operation. Is there a argument i need to put beside xml_data object ??

 

xml_commands_send = connection.dispatch(send_xml_data)

 See the code below:

  

send_xml_data = '''
    <input>
        <destination>8.8.8.8</destination>
        <repeat-count>5</repeat-count>
        <interval>1</interval>
        <source>Loopback0</source>
    </input>
</ping>
'''
also tried this 
send_xml_data = '''
<rpc message-id="101" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0">
        <input>
            <destination>8.8.8.8</destination>
            <repeat-count>5</repeat-count>
            <interval>1</interval>
            <source>Loopback0</source>
        </input>
    </ping>
</rpc>
'''
 
>>> send_xml_data = '''
... <ping xmlns="http://cisco.com/ns/yang/Cisco-IOS-XR-ping-act">
... <input>
... <destination>8.8.8.8</destination>
... <repeat-count>5</repeat-count>
... <interval>1</interval>
... <source>Loopback0</source>
... </input>
... </ping>
... '''

I also tried this  according to the instructions from the link below

LTRSDN-2260 (ciscolive.com)

xml_commands_send = connection.dispatch(send_xml_data, source=None, filter=None)

Hi

Is  the following working?

 

xml_commands_send = connection.rpc(xml_.to_ele(send_xml_data))

 

You need to import xml_ from ncclient:

 

from ncclient import manager, xml_
