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

ron.whitt — Fri, 01 Mar 2019 11:52:18 GMT

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:

<vnfd>

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

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?

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.
