Hi Amy

I thought that this could have been an addition to RFC 7224: IANA
Interface Type YANG Module. I can understand now that this model is
considered just as a reflection of the IF-MIB interface types and is
intended to be updated only when a new interface type is added in
IF-MIB.

<tp>
That is not quite right.  Look at RFC7224 and you will find that it
defines the initial contents of the Interface Type YANG module and
defines the rules for updating that module, that is that a request is
made to IANA for a new interface type and IANA pass the request on to
the Designated Expert who decides whether or not to grant the request.
If the request for a new interface type is granted, the module is
updated; no further process is required.

Also, the Interface MIB is updated at the same time so that the SMI and
YANG versions of the interface type modules stay in step.  Four such
changes have been made so far in 2018, courtesy of ITU-T G.959 and
G.709.

In this case, the I-D, the WG, have made no such request; as I said
before, I did give it some thought but took it no further.

As you say, these types are then not registered.  There could be lots of
other unregistered interface types but since they are not registered, we
do not know!

In the case of RLT and CT interface types, we have two interface types
introduced in the Microwave Radio Link YANG Data Model but not yet
required to be used in some MIB. So they remain unregistered in IANA.
On the other hand, in NETCONF/RESTCONF, no specific ifType numerical
value is required and the radio-link-terminal and carrier-termination
identities specified in  ietf-microwave-types are adequate for this
purpose.
Thanks for your answers.

Hi Theodoros,

I discussed with serveral people at the IETF week, the answer is the
same as Tom gave.
We cannot use a YANG model to ask for IANA registry for MIB.
As YANG is normally used by NETCONF/RESTCONF, MIB is used by SNMP.
If there's interest on MIB, another draft should be sumbitted and ask
for the registry.

BR,
Amy

Hello

I would like to ask a question regarding to ietf-microwave-types module.

For radio-link-terminal and carrier-termination, is it expected that
these new interface-types will be also registered at IANA Interface Type
registry for  IANAifType-MIB?

<tp>

The strict answer is no, they will not be added to the registry.  They
are only added when the IANA Cosiderations asks IANA to do so and this
I-D makes no such request.

If such a request were made, then they would be added both to the
IANA-maintained MIB Module and to the IANA-maintained YANG  module.

I did think of this a year ago and thought them too specific to CCAMP,
worth putting into a YANG module but not inflicting them on the IETF at
large, but do not think this ever got discussed on the WG list.
