I'm getting an "unknown namespace" error when I try to load a VNFD

[ron.whitt]

I'm trying to load a VNFD file into NSO.  I go into config mode and do a load merge on the file.  I get a namespace error as soon as I do.

Any help or suggestions would be greatly appreciated.

Here is the error:

Error: on line 1: unknown namespace: http://tail-f.com/ns/config/3.0 in config

Here are the steps I've taken:

1) done a make clean all on the /esc-ned/src Makefile

2) rebuild the ESC ned

3) reloaded the NED (successfully)

4) done a sync-from on ESC (successfully)

Here is the VNFD file:

Have you added the NFVO packages which contains (among other things) the VNFD YANG model?

[ron.whitt]

Hi Fredrik,

Thanks so much for the quick reply.  Here is what I did:

I followed the procedure in the document nso-esc.pdf to build an ESC NED:

Step 1 Prepare a directory with the ESC YANG files

Step 2 Run ncs-make-package to build a NETCONF NED based on these YANG files.

Step 3 make the NED package

Step 4 Edit the metadata file for the generated NED

This produced a NED based on these YANG files:

esc_config_data.yang*                  esc_opdata_interface.yang*

esc_datamodel.yang*                    esc_opdata_networks.yang*

esc_disk.yang*                         esc_opdata_state_machines.yang*

esc_extension.yang*                    esc_opdata_system_config.yang*

esc_flavor.yang*                       esc_opdata_tenant.yang*

esc_info.yang*                         esc_opdata_volumes.yang*

esc_interface.yang*                    esc_opdata.yang*

esc_kpi.yang*                          esc_policies.yang*

esc_locators.yang*                     esc_port_forwarding.yang*

esc_network.yang*                      esc_property.yang*

esc_notifications.yang*                esc_rules.yang*

esc_opdata_default_locators.yang*      esc_scaling.yang*

esc_opdata_devstats.yang*              esc_types.yang*

esc_opdata_flavor_state_machine.yang*  esc_vim_connector.yang*

esc_opdata_flavors.yang*               esc_volume.yang*

esc_opdata_image_state_machine.yang*   esc.yang*

esc_opdata_images.yang*

I then added ESC as a device and was able to connect and sync with ESC.

So currently the only packages I have in the ncs-run directory are these:

nsoadmin@nso:~/ncs-run/packages$ ls -F

cisco-ios@  cisco-iosxr@  esc-ned/

Am I missing a package?

[frjansso]

Yes, you're missing the NFVO Function Pack. It can be downloaded on software.cisco.com:

Cisco Systems

Select "Network Services Orchestrator ETSI Rel2 NFVO", that archive contains the NFVO FP, which is what you need.
