I agree. At the time when we did ietf-interfaces, not many people had experience with using identities; and we didn't have YANG 1.1. So we just used what we had in the MIB, but as identities. Now that we have much more experience, it would be great to build a better way to identify interfaces and their properties. /martin > > Lada > > On Thu, 2018-04-05 at 23:59 +0000, Alex Campbell wrote: > > I haven't seen any previous discussions on the topic, but we have a similar > > problem. > > Note this is not really to do with YANG itself, so much as the practical > > limitations of the software package that provides our CLI interface. > > In NETCONF, the existence of extra unused identities doesn't pose any > > problem. > > > > From: netmod <netmod-boun...@ietf.org> on behalf of Bogaert, Bart (Nokia - > > BE/Antwerp) <bart.boga...@nokia.com> > > Sent: Thursday, 5 April 2018 8:21 p.m. > > To: email@example.com > > Subject: [netmod] An abundant amount of IANA if types... > > > > Hi, > > > > We were wondering if it would make sense to introduce features in the IANA > > if > > types YANG model to enable grouping of related interface types.
