Here is another proposal for a chassis MIB. An older draft of this
proposal was handed out, on a limited basis, at the last IETF.
I apologize for the late posting. I'll bring along 25 copies with
me, next week.

-- This MIB module uses the extended OBJECT-TYPE macro as defined
-- RFC 1212
-- Textual convention
DisplayString ::= OCTET STRING
-- This data type is used to model textual information taken from
-- the NVT ASCII character set. By convention, objects with this
-- syntax, unless explicitly stated, are declared as having:
--
-- SIZE (0..255)
chassis OBJECT IDENTIFIER ::= { experimental 9999 }
-- chType is, in generic terms, similar to sysObjectID in
-- MIB-II. It is defined for the sake of completeness, and
-- in order to negate dependencies on other MIBs.
chType OBJECT-TYPE
SYNTAX OBJECT IDENTIFIER
ACCESS read-only
STATUS mandatory
DESCRIPTION
"Identifies the type of hub-based or standalone device.
A vendor's authoritative identification of this
chassis or device. By convention, this value is
allocated within the SMI enterprises subtree(1.3.6.1.4.1),
and provides an easy and unambiguous means for
determining `what kind of box' is being managed. If this
information is not present or unknown, its value should
be set to the OBJECT IDENTIFIER { 0 0 }, which is a
syntactically valid object identifier."
