@prasadsriramps Thanks for your work. Are you testing this with an actual device?

[prasadsriramps]

Apologies. forgot to attach test logs. updated the PR description to add the same.

[ishidawataru]

Thanks. The test logs look really good.

Can you update here to include mode inside the state container?

Goldstone YANG models follow the config / state structure of OpenConfig models.

When querying the sysrepo operational datastore, the config containers in the model are populated automatically by copying the contents of the sysrepo running datastore. This indicates the configuration intention of the operator. On the other hand, the state containers need to be populated manually in the oper_cb to share the actual status of the system.

Hi Wataru,

The requested changes have been made.

I also bring to your attention another PR in the usonic repository (oopt-goldstone/usonic#6) that addresses the teamd related changes for static portchannel. Kindly review them whenever possible.
