Hi Team

nxos_config module where Ansible cannot able to return below highlighted information from device rather it returns the config as changed.

Is this a bug? please help

Manual:

lab.device.local(config)# logging server x.x.x.x 6
Can’t configure more than 8 IP Servers

Through Ansible:

changed: [lab.device.local] => {
“changed”: true,

“logging server x.x.x.x 6”,
“logging server x.x.x.x 6”
],

Hi Pushparaj,

You can try to use changed_when. Haven't used nxos_config unfortunately yet.

Best,

See 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 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!
