hi Actually, the issue was more/also whether there was consensus to change the current MIB a lot to diverge from the ITU-T model. We've diverged from it as has made sense to the working group, but there were a few requests for changes such as object renaming which in my personal view didn't make sense to do since they seemed non-value add changes. My take on consensus to diverge further is that we are somewhat split on the issue.

Unless you disagree with my assessment, Sharon should mark this issue as closed. Margaret At 12:30 PM -0800 3/25/04, Randy Presuhn wrote: >Hi - > >> From: "David T.
