Degraded minutes in 3895bis

["C. M. Heard" <heard@pobox.com>]

HI,

About a month ago Orly Nicklass proposed making some additions to the
DS1-MIB in RFC 3895 and issuing a revised RFC 3895bis.  In a recent
thread on the newsgroup comp.dcom.sdh-sonet it was stated that degraded
minutes counters are no longer relevant, according to current performance
ANSI/ITU monitoring standards.  If that is true, then it might be
appropriate to deprecate the degraded minutes counter(s) and write new
compliance statements for 3895bis.

Regards,

Mike Heard

Note that RFC 2495 has been superseded by RFC 3895.  From
ftp://ftp.isi.edu/in-notes/rfc-index.txt we have:

3895 Definitions of Managed Objects for the DS1, E1, DS2, and E2
     Interface Types. O. Nicklass, Ed.. September 2004. (Format:
     TXT=163841 bytes) (Obsoletes RFC2495) (Status: PROPOSED STANDARD)

This version adds a few objects and corrects some errors that were in
the previous version.

I didn't know that.  I will forward this information to the appropriate
IETF discussion list.  There has been some discussion of issuing an
update to RFC 3895;  if that happens, then the degraded minutes counter(s)
should be deprecated and new compliance statements should be written.
