3-6 Using Total Control MIBs
The Chassis MIB
The Total Control chassis MIB is an enterprise-specific MIB loosely
based on an early draft standard under development by the
Chassis MIB Working Group (since disbanded), under direction of
the IETF (Internet Engineering Task Force). The Total Control
chassis MIB provides SNMP identification and indexing for
modems and other managed modules in the Total Control MP/16.

Slots and Entities
A full-scale chassis, such as the Total Control Enterprise Network
Hub, contains up to 17 slots. Each slot can house any of several
removable managed modules called Network Application Cards
(NACs), often referred to simply as “cards.” A card can occupy
any slot in the chassis, and can contain various manageable entities
,
depending on what type of card it is.
The term
card
is used to describe a managed module in the MP/16,
while slot is used to describe its location. Entity appropriately
describes each of the eight modems in each MP/16 modem module
and the SNMP proxy agent in the management module.
Slot and Entity Tables
The chassis MIB includes two main tables: the first defines
slots
(uchasSlotTable) and the second table defines the manageable
entities
(uchasEntityTable) that appear in a card or module.
The slot and entity tables are sparse tables. That means that there
can be "holes" in the tables, or missing rows where modules or
entities may not be physically present. The chassis’s proxy agent
adds rows to the slot table for each card discovered in a chassis,
and rows to the entity table for each managed entity found on
those cards.
