I am trying to create and run the openconfig script which is shown as a sample in DevNet tutorial NETCONF/YANG on Nexus Part 3: Using OpenConfig YANG Models on Nexus Switches. The file as an example is add_oc_loopback.py.
The file contents are :
#!/usr/bin/env python from ncclient import manager import sys from lxml import etree # Add parent directory to path to allow importing common vars sys.path.append("..") # noqa from device_info import sbx_n9kv_ao as device # noqa # Loopback Info - Change the details for your interface loopback = {"id": "98", "ip": "10.98.98.1", "prefix": "24"} # create a main() method def main(): """ Main method that adds loopback interfaces """ add_oc_interface = """<config> <interfaces xmlns="http://openconfig.net/yang/interfaces"> <interface> <name>lo{id}</name> <config> <description> Configured using OpenConfig Model </description> <name>lo{id}</name> <type>ianaift:softwareLoopback</type> </config> <subinterfaces> <subinterface> <index>0</index> <ipv4> <addresses> <address> <config> <ip>{ip}</ip> <prefix-length>{prefix}</prefix-length> </config> <ip>{ip}</ip> </address> </addresses> </ipv4> </subinterface> </subinterfaces> </interface> </interfaces> </config>""".format(id = loopback["id"], ip = loopback["ip"], prefix = loopback["prefix"]) # print(add_oc_interface) with manager.connect(host = device["address"], port = device["netconf_port"], username = device["username"], password = device["password"], hostkey_verify = False) as m: # Add the loopback interface IP print("\nNow adding IP address {} to interface lo{} on device {}...\n".format(loopback["ip"], loopback["id"], device["address"])) netconf_response = m.edit_config(target='running', config=add_oc_interface) # Parse the XML response print(netconf_response) if __name__ == '__main__': sys.exit(main())
Could not attach it as it was saying
The contents of the attachment doesn't match its file type.
The error I get after changing the parameters to my switch IP, user,pwd , etc. is :
Element 'config': This element is not expected. Expected is one of ( {urn:ietf:params:xml:ns:netconf:base:1.0}default-operation, {urn:ietf:params:xml:ns:netconf:base:1.0}test-option, {urn:ietf:params:xml:ns:netconf:base:1.0}error-option, {urn:ietf:params:
I changed to include
<rpc message-id="101" xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"> <edit-config> <target> <running/> </target>
However, I get another error:
Element [{urn:ietf:params:xml:ns:netconf:base:1.0}rpc] does not meet requirement
Please help or advise!!
