Unable to Reload package with New Template

[abhinavr5289]

Hi 

We are unable to load the newly created Service Package with updated Yang, can someone please help why it's failing here?

reload-result {
package PE_CE_8_1
result false
info PE_CE_8_1-template.xml:246 Element: 'fib-quota' only exists for ned-id: npt12500_8.1.01060-nc-1.0:npt12500_8.1.01060-nc-1.0
}

should Template XML support all configured NEDs? because this FIb Quota is newly added in Yang and is only available in NED npt12500_8.1.01060-nc-1.0. other NED yang has no attribute "Fib-quota".

Regards

Hi,

There's an option called if-ned-id you can add in your template so the processing is conditional on matching a specific ned (and the element you are concerned about). It's explained here https://community.cisco.com/t5/nso-developer-hub-discussions/error-element-only-exist-for-a-ned-id/td-p/4034137

thanks

Hi @RichardD2 ,

Thanks, I have added conditions as per the above resolution and now Sync-from passes successfully. Also, the result against that problematic template is True.

But, I am still not able to execute that service also that is not able in UI? any suggestions?

Thanks,

What is the error that you are seeing in the UI? More info would be helpful. Maybe you can post a screenshot?

thanks

Hi @RichardD2 ,

There is no Error in UI or CLI, after adding conditions in XML for the package we are able to complete Sync-from successfully.

but we are not able to see the package in UI or CLI to proceed further for configuration.

Ex- after creating a package, we do package reload to highlight service in UI/CLI to do configuration. but hereafter successful configuration we still not able to see that newly created package available for configuration.

Thanks

Ok, from the ncs_cli what is the output of 'show packages package oper-status'?

If your package doesn't even make it into the list, I would be checking to see that it's in the right directory. 

The recommendation I follow is to make sure its in the packages directory

From the developer guide:

When NSO starts, it needs to search for packages to load. The ncs.conf parameter /ncs-config/
load-path defines a list of directories. At initial startup, NSO searches these directories for packages,
copies the packages to a private directory tree in the directory defined by the /ncs-config/statedir
parameter in ncs.conf, and loads and starts all the packages found. All .fxs (compiled YANG files)
and .ccl (compiled CLI spec files) files found in the directory load-dir in a package are loaded. On
subsequent startups, NSO will by default only load and start the copied packages - see the section called
“Loading Packages” for different ways to get NSO to search the load path for changed or added packages.

thanks

HI @RichardD2,

The below package is operationally up, but I am not able to see it to do configuration.

packages package PE_CE_8_1
oper-status up

admin@ncs(config)# PE
^
% Invalid input detected at '^' marker. >> Here is should auto-complete, but no luck.

Thanks

In order to troubleshoot this further, we need to see the service package. Can you post your YANG model and XML template?

thank you,

HI @RichardD2 ,

Please refer to the attached files.

Thanks for posting the files. At first glance, this block doesn't look correct:

</route-targets>
                        <?if-ned-id npt12500_8.1.01060-nc-1.0:npt12500_8.1.01060-nc-1.0?>
                        <?elif-ned-id npt1050_8.1.01060-nc-1.0:npt1050_8.1.01060-nc-1.0?>

I believe you need to make it look like:

</route-targets>
<?if-ned-id npt12500_8.1.01060-nc-1.0:npt12500_8.1.01060-nc-1.0 npt1050_8.1.01060-nc-1.0:npt1050_8.1.01060-nc-1.0?>

You just need to separate the ned-ids with a space instead of using elif right after.

HI @RichardD2 ,

Changes done as per your above reply but still issue is there, we are not able to see the package for further configuration.

reload-result {
package PE_CE_8_1
result true
}

admin@ncs# PE
^
% Invalid input detected at '^' marker.

Thanks

So you login to ncs_cli type 'PE' and then you get the error?

If you are wanting to deploy an instance of your service, you need to be in config mode

admin@ncs# conf
Entering configuration mode terminal
admin@ncs(config)#

Then type PE and enter the attributes for your service.

thanks
