Hi,

 

We have a question regarding the statistics container as defined in the
interfaces-state model.  This container defines one mandatory leaf
(discontinuity-time) while all other leafs are optional.  What is the
rationale behind this leaf being mandatory and not an optional field?

It does not make a lot of sense to return a discontinuity-time value and no
counters if none of the counters are relevant for a specific interface.

Another alternative could be to add, via a deviation, a when clause to the
container indicating for which ifType(s) the container is (or is not)
present. But that would lead to not supporting the IETF interfaces model to
the full extent.

 

Regards, Bart
