From: "David L. Arneson" <arneson@ctron.com>
I felt it was important to present the other view of the chassis MIB
for your approval.
After reading thru this there are a number of errors that need fixing
but this does get the idea across.
This differs from the previous by the module identification which is done
by it's physical location within the chassis. I also merged the 3
tables of resource, physical config, logical config into 2 tables. I
believe that this is as Pete Wilson proposed.
So we need to determine which of these best suites the needs.
I'm sure there are many errors within the MIB. If we can reach some form
of agreement I will flesh out the next one to be correct in all respects.
So which view do you perfer?

state. A value of operational(4) implies that the
entity is running with no errors or warnings.
State resetInProgress(5) implies equivalent of
setting phyAdminStatus to reset(4). The states of
warning(6), nonFatalError(7), fatalError(8)
reflect conditions detected during operation. The
entity may or may not be still functional.
For example if a modules value of phyAdminStatus
