Hi everyone,
I am banging my head against the wall on this one. I am writing an Ansible playbook using NETCONF that retrieves a list of interfaces that have an ACL configured and then using the XML response, create a new payload that removes the ACL. I am able to get the interfaces no problem using a XPath filter but I cannot figure out how to handle the multiple interface types when creating the payload to send back.
I am using Ansible's parse_xml filter to convert the XML response into a data structure I can then use to template out the XML payload. The issue I am having is I cannot figure out how to capture the interface type tag when parsing the XML. The only way I can make it work is to statically set the interface type (e.g. GigabitEthernet or FiveGigEthernet) and loop over that. The issue with that approach is I have to add every possible interface type to my playbook.
Has anyone done this before? Almost 100% of tutorials / examples for NETCONF show how to modify a single interface and nothing more advanced than that (maybe I'll write one when I figure this out :|)
Here's the xml spec for parse_xml filter I'm using (currently looping only over GigabitEthernet):
---
keys:
result:
value: "{{ interfaces }}"
top: native/interface/GigabitEthernet
items:
name: name
vars:
interfaces:
name: "{{ item.name }}"
Here's the xml jinja template I'm using for the payload (this is an example, needs to be tweaked once parsing works) :
<target>
<running/>
</target>
<config>
<native xmlns="http://cisco.com/ns/yang/Cisco-IOS-XE-native">
<interface>
{% for itype,intfs in interfaces.output.data.native.interface.items() %}
{% for intf in intfs %}
<{{ itype }}>
<name>{{ intf.name }}</name>
<ip>
<access-group xmlns:nc="urn:ietf:params:xml:ns:netconf:base:1.0" nc:operation="delete"/>
</ip>
</{{ itype }}>
{% endfor %}
{% endfor %}
</interface>
</native>
</config>
