nxos_command using the src option

[Matt Mullen]

I'm using the src parameter of nxos_config to enter several configuration lines at once.  When it detects that one of the lines differs from the running configuration,  does it push the entire block from the src file or just the line that was different?   Also is there any way to display the line or lines that were updated in Ansible?  

My test playbook looks like this:

---
- hosts: evpn_leaf
  vars:
    cli:
      host: "{{ inventory_hostname }}"
      username: admin
      password: cisco
      transport: cli


  tasks:



    - name: Send configuration commands from file to switch

      nxos_config:
        provider: "{{ cli }}"
        src: config.txt
      register: result


    - name: Display the result of the task

      debug: var=result verbosity=0

The config.txt file has these lines:

router eigrp 200


interface Ethernet1/48
  description testing2
  no switchport
  ip address 1.1.1.1/24


router bgp 65000

Every time I run this,  I get a changed result and configuration is applied.  I think the reason is that 'no switchport' is a default configuration and does not appear in the running configuration on the switch.  In this case is Ansible just applying the 'no switchport' command,  or all of the config commands in the config.txt file?   Is there any way to display in Ansible the config lines that were applied?   

Here is the output...
