YANG model support

[Ian Barrere]

Hello,

I'm running SONiC.master.436897-2ba3c90ad on a Mellanox ACS-MSN2700. I have done almost nothing with it and I'm quite new to SONiC in general. The rest of our hardware uses gNMI and/or RESTCONF for management, so I'd like to use the same for SONiC if possible, but it seems like the models out of the box are quite limited. I have seen things elsewhere alluding to more support, so I'm not sure if it's just a matter of adding YANG models to some directory or what.

For example, if I visit /ui after the web URL for my switch I see the following models supported:

Likewise, if I run a get-capabilities via gNMI I see the same set. I see plenty of other YANG models on the system in various locations (/usr/local/yang-models/, etc), but those don't seem to be available on the interfaces.

Is it possible to extend the set of capabilities on the programmatic interfaces with more YANG models?

Thanks,

Ian

hi Ian,

RESTCONF server loads only the sonic yangs listed in import.mk file from /usr/local/yang-models directory, plus these sonic yangs. Hence you are seeing only few sonic yangs in the ui.. You can update the import.mk file and prepare a new build to view additional sonic yangs. However there may be some runtime failures.

Regards

Sachin

Hi Sachin,

Thanks for the feedback, this is exactly what I was looking for. You mention that more sonic YANG models can be loaded, but are any more common YANG models available as well? In particular I'm interested in openconfig-routing-policy.yang, for example. I can make do with the sonic models as well if necessary, just trying to gauge the current level of OpenConfig adoption.

Best,

Ian

Hi Jeff,

Can you comment on the openconfig-routing-policy.yang support?

Thanks

Sorry, missed this thread while we were out for the winter holiday.

The transformations for that OC YANG model need to be scoped and roadmapped still. For this upcoming release we're working on OC YANG models pertaining to interfaces and VLAN configs. 

For your immediate needs, you could make do with the sonic models, as you surmised.

 

Thanks,

Jeff
