Yes, you interpreted my awful typing correctly.
I don't see any need for anything more, but was allowing that I am not
fully current on the groups thinking.
Yours,
Joel

If the I2RS aren't is off then the system does not currently support
this models. This is just like any other optional YANG module. If you
are not currently prepared to use it, you don't claim to support it.
Sue: I assume you desired to say… if the I2RS is not on, then the
system does not support this model.
Caveat: The NetMod folks may have come up with a more nuanced mechanism.
Sue: Do we need them to come up with mechanism that indicates I2RS is
there but off?

Joel:
What happens if the code supports the I2RS agent, but the I2RS agent is
configured to be "off"? Is this covered by the deviations or is this
variable configuration?

As I understand it, if a model requires ephemeral elements, and the
agent does not support ephemeral, then the agent can not claim to
support the model.
Yes, deviations allow you to specify this, as Andy says. But this is
specifying a failure to conform.
I would go far as to say that such an agent is not an I2RS agent, but
that is a step beyond the NetConf compliance definitions.
Yours,
Joel

Andy and Joel:
These are good points.
What happens if the data model has some ephemeral sections and the
I2RS agent is not supported by the routing system. The data model
would specify the ephemeral section, but there would be no support by
i2rs.
Is the support of the ephemeral not a variable condition to be
indicated in Yang module library?

Reading the latest revision, in section 3.1.1, the text in bullet 5
says that the data model indicates which portions are ephemeral.
That makes sense to me.
Then bullet 6 says that the management protocol needs to signal (in
its yang library) which parts are ephemeral.
Why the second requirement? If the data model is supported, and the
data model states that certain items are ephemeral, what would it
mean if the signaling did not also say that. Conversely, what would
it mean if the signaling said something was ephemeral that the model
does not define as ephemeral?
It may be that I am misreading bullet 6. Please explain.
I think you are correct that the YANG library does not need any
changes to identify ephemeral data. Only the variable components of
YANG conformance are contained in the library.
Thank you,
Joel
