6 Configuring SNMP

This chapter describes the Nokia IPSO implementation of Simple Network Management Protocol (SNMP) and how to configure it on your system.

SNMP Overview

The Simple Network Management Protocol (SNMP) is the Internet standard protocol used to exchange management information between network devices. SNMP works by sending messages, called protocol data units (PDUs), to different parts of a network. SNMP-compliant devices, called agents, store data about themselves in Management Information Bases (MIBs) and return this data to the SNMP requesters.

IPSO implements UCD-SNMP 4.0.1 as the base version of SNMP. Changes have been made to the base version to address security and other fixes. For more information on Net-SNMP, go to http://www.net-snmp.org.

Caution

If you use SNMP, Nokia strongly recommends that you change the community strings for security purposes. If you do not use SNMP, you should disable the community strings.

SNMP, as implemented on Nokia platforms, supports the following:

„GetRequest, GetNextRequest, GetBulkRequest, and a select number of traps. The Nokia implementation also supports SetRequest for three attributes only: sysContact,sysLocation, and sysName. You must configure a read-write community string to enable set operations.

„SNMP v1, v2, and v3. For more information about SNMP v3, see “Managing SNMP Users.”

Note

The Nokia implementation of SNMPv3 does not yet support SNMPv3 traps.

„Other public and proprietary MIBs as follows.
