Cannot configure service instances via YANG on 17.2 due to wrong CLI commands #33

Open sebageek opened 4 years ago

sebageek commented 4 years ago

It looks like the YANG stack generates wrong CLI commands to configure a service instance on a port channel. YANG generates service-instance, CLI refuses this, probably wants service instance.

For your convenience, here is the full YANG call we're doing and the response.

Cisco advised us not to use <service-instance>, as it is only present for backwardscompability, but to use <service-instance-list><service-instance>{id}</service-instance></service-instance-list> for each entry. The same goes for #28. Will try out.
