Node missing when compiling YANG models

fwclements1 — Fri, 01 Mar 2019 11:58:48 GMT

Good day fellow NOS'ers!

I've been working through trying to compile a NETCONF NED for a TelcoSys T-Marc box - they say they support it. After getting my hands on their YANG models and having to clean up a bunch of XPath errors with 'tailf:dependency '../'' in some must clauses, I'm finally at a point where we're now building the 'augmented' YANGs and hitting an odd error (bottom of the pioneer build output).

What am I missing here? I'm admittedly not super familiar with the intricacies of YANG modeling/syntax so I'd be happy to provide whatever output is needed.

We managed to get a use case working between NSO and a BATM on the EANTC NETCONF/YANG interop earlier this year, so something is likely possible here too. It may be that you have to disable a few YANGs, or hack the YANGs a little for things to work. The confd_dyncfg.yang should actually not be published by BATM, so this is something we should discuss with them. If you have a contact name there, I'd reach out.

I can take a look at the YANGs to see what can be done if you supply them to me.

Thanks! I would definitely appreciate a look and some guidance on what we could disable. All the YANG files I got from them are located here: https://www.dropbox.com/sh/52kyl1t865w61ov/AABxYsqWp2TYyBRfty00bySPa?dl=0

I put a tarball in there as well for quicker download.

Re: Node missing when compiling YANG models

Jan Lindblad — Wed, 30 Aug 2017 15:00:58 GMT

Thanks. I looked at batm.yang that you had trouble with, and edited out the bad+unnecessary stuff from it. Try replacing the batm.yang you downloaded with this:

module batm {

namespace "http://batm.com";

prefix batm;

import tailf-common {

    prefix tailf;

}

container ethernet {

    //tailf:cli-suppress-show-path;

    tailf:cli-incomplete-show-path;

    tailf:cli-add-mode;

    description "Configure Ethernet protocols";

}

}

If you encounter further issues, let's take them offline.

Re: Node missing when compiling YANG models

fwclements1 — Wed, 30 Aug 2017 19:57:19 GMT

SUCCESS!!

Thanks a ton for the help here Jan, very much appreciated! I had to tweak up some paths in the security.yang model. For example:

2418	list ip-std-acg {
2419	tailf:cli-exit-command "exit";
2420	must "(current()/type!='in') or not(../../../ip/access-list/standard[id=current()/id]/rule[*]/fc)"{
2421	error-message "Access-list with FC rule not supported on ingress.";
2422	tailf:dependency '../../../ip/access-list/standard';
2423	}

Originally line 2420 had 'must "(current()/type!='in') or not(/ip/access-list/standard[id=current()/id]/rule[*]/fc)"{'

Which leads me to the question. Is there an easier way to reference top of the current module in these cases? Not that it's a huge deal but the way I figured this out was using yanger to just print each leg of the tree one by one counting up the levels. Seems inefficient. Wasn't sure if there's a top() function that just roots the path up to the current module.

I'll update the yang models on the dropbox link and include the package that was built from pioneer in the tarball.

Re: Node missing when compiling YANG models

No need for top(), simply starting the path with slash / does just that. But there's a major difference between a relative path and an absolute, even if they end up pointing to the same element. An absolute path would refer to *all mathcing instances* in the tree, while a relative path with some double dots ../../ in the path preserves the keys in the path, so as to only point to the current instance. Huge difference.

Would it be possible for you to connect me with someone at BATM? I have some model review issues to discuss with them 😉
