Re: [Entmib] #355: OSI State to Something New Spectrum

["Randy Presuhn" <[e-mail]>]

Hi -

I think Sharon has stated my position more accurately.

I think that what the ITU-T model actually requires has at times
been overestimated here, and that some of the divergence
unnecessarily complicates things.

However, if folks feel the added complications are needed for
SNMP-based management, I'm willing to go along with it,
especially since I don't need to implement it.  :-)
