Select NED for service

[Fantolino]

I'm defining a service that request feature on a NED available only for selected NED version.

If I define the template as usual I got erro at load-time:

reload-result {
package snfeSERVICE
result false
info snfeSERVICE-SNMP-template.xml:109 Element: 'permit' only exists for ned-id: huawei-vrp-cli-6.68:huawei-vrp-cli-6.68, huawei-vrp-cli-6.73:huawei-vrp-cli-6.73

I read Templates - Network Services Orchestrator (NSO) v6.1 - Cisco DevNet. I follow the instruction and create a package-meta-data.xml accordingly:

<ncs-package xmlns="http://tail-f.com/ns/ncs-packages">
<name>snfeSERVICE</name>
<package-version>1.0.4</package-version>
<description>Servizio per Sinfonia Easy - Componente stateful di snfe</description>
<ncs-min-version>5.7</ncs-min-version>

<component>
<name>main</name>
<application>
<python-class-name>snfeSERVICE.Main</python-class-name>
</application>
</component>
</ncs-package>

<supported-ned-id xmlns:huawei-vrp-cli-6.73="http://tail-f.com/ns/ned-id/huawei-vrp-cli-6.73">
huawei-vrp-cli-6.73:huawei-vrp-cli-6.73
</supported-ned-id>
<supported-ned-id xmlns:huawei-vrp-cli-6.68="http://tail-f.com/ns/ned-id/huawei-vrp-cli-6.68">
huawei-vrp-cli-6.68:huawei-vrp-cli-6.68
</supported-ned-id>

But no effect!

Where I'm wrong?

[huayyang]

can you try putting the "permit" tag in a <?if-ned-id?> block? see https://cisco-tailf.gitbook.io/nso-docs/guides/development/core-concepts/templates#ch_templates.xml_instructions 

[Fantolino]

I'm confused. Your suggestion seems to refer to the XML templates, but my question is about the package-meta-data.xml file.

[huayyang]

now I'm not sure what the question really is... do you want to be able to load the service package? or do you want to know why having <supported-ned-id> in package-meta-data.xml gave you "no effect"?

[Fantolino]

The latter.
I'd like to have simple templates, that does not include NED information, because, if I have to add new NEDs I should modify all the template files.
I read that it is possibile to limit the NED versions applicable declaring them in the packeg-meta-data.xml file. I tried but it seems to have no effect: the package operates also on devices with NED ids not included in package-meta-data.xml supported-ned-id tags

[huayyang]

 I can't reproduce your observation that "the package operates also on devices with NED ids not included in package-meta-data.xml supported-ned-id tags", if I have:

1 2 versions of the same ned loaded, let's say 1.0 and 1.1

2 a template with no <?if-ned-id?> + a tag that only exists in 1.1

3 <supported-ned-id> declares support for 1.1

applying the template gave me: unit-template.xml:6 will not apply template to device ex0 with unsupported ned-id: router-nc-1.0:router-nc-1.0. The template is only available for supported ned-id(s) router-nc-1.1:router-nc-1.1
