Overview of SNMP MIBs

Simple Management Network Protocol (SNMP) development and use is centered around the
Management Information Base (MIB). An SNMP MIB is an abstract data base, i.e., a conceptual
specification for information that a management application may read and modify in a certain form. This
does not imply that the information is kept in the managed system in that same form. The SNMP agent
translates between the internal data structures and formats of the managed system and the external data
structures and formats defined for the MIB.
The SNMP MIB is conceptually a tree structure with conceptual tables. Cisco 3G MIB is discussed in
more detail in the next section. Relative to this tree structure, the term MIB is used in two senses. In one
sense it is actually a MIB branch, usually containing information for a single aspect of technology, such
as a transmission medium or a routing protocol. A MIB used in this sense is more accurately called a
MIB module, and is usually defined in a single document. In the other sense a MIB is a collection of
such branches. Such a collection might comprise, for example, all the MIB modules implemented by a
given agent, or the entire collection of MIB modules defined for SNMP.
A MIB is a tree where the leaves are individual items of data called objects. An object may be, for
example, a counter or a protocol status. MIB objects are also sometimes called variables.
MIBs can be classified into three categories:
•
•

3G Cellular WAN MIB Architecture
This section describes the MIB definition and implementation support for Cisco's cellular 3G WAN
products on the customer premises equipment (CPE) end.
The 3G Cellular WAN MIB supports both CDMA and GSM set of cellular standards and includes the
following technologies:
•
•
The 3G cellular MIB uses indexes from the cellular interface and from the modem. You can obtain the
interface index using IF-MIBs and the modem index using the ENTITY MIBs.

Cisco-Entity-Vendortype-OID-MIB.my—ENTITY-MIBs are used to provide general hardware type
for both the HWIC and the modem. CISCO-ENTITY-VENDORTYPE-OID-MIB assigns OIDs for
Cisco components (including the HWICs & the modems). The OIDs are then used as the values of
entPhysicalVendorType in the ENTITY-MIB.
