3.3.10.7 The ATM MIB

ATM objects have OID {1.3.6.1.2.1.37}, as shown in Figure 3-17. This MIB module consists of nine groups.


Figure 3-17.  ATM managed objects

The ATM Interface Configuration Parameters group contains configuration information associated with an ATM interface, which supplements the information provided in MIB-II. The ATM Interface DS3 PLCP group contains configuration and state parameters for DS3-based ATM interfaces. The ATM Interface TC Sublayer group contains Transmission Convergence configuration information and state parameters. The ATM Traffic Descriptor Parameter group contains traffic parameters such as the QoS class. The ATM Interface Virtual Path Link (VPL) group contains configuration and state information of a bidirectional VPL. The ATM Interfaces Virtual Channel Link (VCL) group contains configuration and state information of a bidirectional VCL. The ATM Virtual Path (VP) Cross Connect group contains configuration and state information of all point-to-point, point-to-multipoint, or multipoint-to-multipoint VP cross connects. The ATM Virtual Channel (VC) Cross Connect group contains configuration and state information of a bidirectional VC cross connect. The AAL5 Virtual Channel Connection (VCC) Performance Statistics group contains AAL5 VCC performance parameters.

RFC 1695 [3-14] defines the ATM MIB.

3.3.11 The SNMP Group

Since this book is about SNMP, you should be especially interested in the SNMP group, which provides information about SNMP objects (see Figure 3-18). There are a total of 30 scalar objects in this group, including SNMP message statistics, the number of MIB objects retrieved, and the number of SNMP traps sent. This group is designated {1.3.6.1.2.1.11}.

3.4. Other MIBs

The growing need for network management in general, along with SNMP’s popularity, has led to the definition of a number of MIBs that support specific network architectures or platforms. Included are MIBs to support a specific architecture, protocol, or interface, and those that support specific transmission media types.

3.4.1 Specific-use MIBs

The following table lists the currently approved Internet-standard MIBs included under the MIB-II subtree that support a specific architecture, protocol, or interface:
