How to ignore warnings

[Brian Nelson]

I'm trying to homogenize the JunOS configs on a few dozen EX2200 with an ansible-playbook. Using an EX2200.set file, I have "delete [element]" commands to delete configuration statements which may or may not exist. If the configuration statement does not exist, JunOS returns "warning: statement not found"; and the config fails.

ignore_errors and other error handling functions outside the junon_install_config function, and has no effect.

Suggestions on how to approach this problem?

Hi Brian,

Will try to figure out what option can be provided to handle this scenario. Mean time you can edit our module to get control of the warning. 

Please follow below steps:

1. You will find our modules as /etc/ansible/roles/Juniper.junos/library
2. Edit below lines (in the url) to ignore warning with below code

https://github.com/Juniper/ansible-junos-stdlib/blob/master/library/junos_install_config#L254-L257

    cu.load(**load_args)
except (ValueError, ConfigLoadError, Exception) as err:
    if err.rpc_error['severity'] == 'warning':
        logging.info("Ignoring warning: %s"% err.message) #or u can use logging.warning
    else:
        msg = "Unable to load config: {0}".format(err)
        logging.error(msg)

Or replace the attached file (with the modification) with /etc/ansible/roles/Juniper.junos/library/junos_install_config.

Do let me know if you face any problem.

Thanks

Nitin Kr

Thanks for the quick fix; but, the update is still failing.

Hi Brian,

As you can see incase of multiple warning, exception severity is None 

msg: Unable to load config: ConfigLoadError(severity: None, bad_element: None, message: warning: statement not found warning: statement not found

This looks to be a bug from PyEZ side. Cn you please raise an issue on github. I will try to fix the same and keep you posted.

Thanks

Hi Brian,

The issue from PyEZ has been fixed. https://github.com/Juniper/py-junos-eznc/pull/501

Now with latest code in github severity will be returned as warning in case of multi warning errors.

To have latest PyEZ, use below command to get it from github master branch

pip install -U junos-eznc

In addition to latest PyEZ used attached ansible module (in 2nd last email) for your purpose.

Thanks
