NSO YANG compatibility issue

Hi,

 

Using NSO 5.3 and 6WIND Turbo Router, I am able to build a NED package, but I have a the following problem when loading it:

 

admin@ncs> request packages reload

>>> System upgrade is starting.
>>> Sessions in configure mode must exit to operational mode.
>>> No configuration changes can be performed until upgrade has completed.
>>> System upgrade has been cancelled.
Error: Failed to load ./state/packages-in-use/1/vrouter/load-dir/vrouter-fast-path.fxs: Module tailf-ncs: The target of the leafref path for node /devices/device/config/config/system/fast-path/port, augmented from module vrouter-fast-path, does not exist 
[error][2019-10-18 00:21:42]
admin@ncs>

 

 

I was told this is a known NSO compatibility issue with the following YANG 1.1 code:

 

    leaf-list port {
      type leafref {
        path
          "/vrouter:state/vrouter-network-ports:network-port/vrouter-network-ports:name";
        require-instance false;
      }
      description
        "A physical network port managed by the fast path.";
    }

 

This issue would be fixed in NSO 5.1.3 and 5.2.2. How can I access these releases?

And when will a 5.3 release with the fix be available?

 

Thanks in advance for your help!

Yann

Hi, I don’t recognize the issue – but for both the ticket question and access to versions of NSO not on DevNet you should go through a partner contact.
