Chapter 7. SNMP Adapter

The Simple Network Management Protocol (SNMP) adapter for the IBM Tivoli Enterprise Console product forwards events from SNMP traps to the event server.

This chapter explains how to configure and start the SNMP adapter.

SNMP Driver

The SNMP adapter serves the function of collecting SNMP trap messages directly from the SNMP trap socket of a host and translating SNMP traps into appropriate IBM Tivoli Enterprise Console class instances.

The SNMP manipulation routines make use of SNMP Research SNMP libraries.

Reception of SNMP Messages

The SNMP adapter receives SNMP traps by listening directly on socket udp/162 of the host it runs on.

Incoming Messages Format

Messages received on the udp/162 socket consist only of SNMP Trap-PDUs as defined in RFC 1157 (SNMPv1). Other types of messages are discarded.

Server Configuration

Since the SNMP trap adapter listens on UDP socket 162 for incoming SNMP traps, it must be run as root. Also, UDP socket 162 must not already be in use by another SNMP manager, such as the trapd daemon for IBM NetView for AIX® or the SNMP trap daemon itself.

Adapter Files

The SNMP adapter package consists of the following files:

tecad_snmp.cfg

The installation script.

tecad_snmp The adapter executable file.

tecad_snmp.baroc

The BAROC file.

tecad_snmp.cds

The class definition statement (CDS) file.

tecad_snmp.conf

The configuration file.

tecad_snmp.err

The error file.

tecad_snmp.oid

The object identifier file.

init.tecad_snmp
