Hi Pushparaj,

You can try to use changed\_when. Haven't used nxos\_config unfortunately yet.

Best,  
Karol

See [https://docs.ansible.com/ansible/devel/user\_guide/playbooks\_error\_handling.html#defining-changed](https://docs.ansible.com/ansible/devel/user_guide/playbooks_error_handling.html#defining-changed) for more details on changed\_when.

Hi Pushparaj,

This seems to happen because the stderr regex in the NX-OS terminal plugin doesn’t catch “Can’t configure more than 8 IP Servers”. However, with Ansible 2.9, the stdout and stderr regexes were made configurable options. Please refer to [https://docs.ansible.com/ansible/latest/network/user\_guide/network\_debug\_troubleshooting.html#task-failure-due-to-mismatched-error-regex-within-command-response-using-network-cli-connection-type](https://docs.ansible.com/ansible/latest/network/user_guide/network_debug_troubleshooting.html#task-failure-due-to-mismatched-error-regex-within-command-response-using-network-cli-connection-type) for more information.

In this particular case, you can try adding the following to the task:  
vars:  
ansible\_terminal\_stderr\_re:

- pattern: “can’t configure (.\*)”  
flags: 're.I

Thanks!
