618 Chapter 12 Configuring SNMP
320818-A
Simple Network Management Protocol (SNMP) is a set of protocols for managing
complex networks. SNMP works by sending messages, called protocol data units
(PDU), to different parts of a network. The SNMP-compliant agents on the Nortel
SNAS 4050 devices store data about themselves in Management Information
Bases (MIB) and return this data to the SNMP requesters.
There is one SNMP agent on each Nortel SNAS 4050 device, and the agent listens
to the Real IP address (RIP) of that particular device. On the Nortel SNAS 4050
that currently holds the cluster Management IP address (MIP), the SNMP agent
also listens to the MIP.
The SNMP agent supports SNMP version 1, version 2c, and version 3.
Notification targets (the SNMP managers receiving trap messages sent by the
agent) can be configured to use SNMP v1, v2c, and v3. The default is SNMP v2c.
You can specify any number of notification targets on the Nortel SNAS 4050.
For information about the MIBs supported on the Nortel SNAS 4050, see
Appendix C, “Supported MIBs,” on page 875 .
Configuring SNMP using the CLI
To configure SNMP for the Nortel SNA network, access the SNMP menu by
using the following command:
/cfg/sys/adm/snmp
From the SNMP menu, you can configure and manage the following:
• general settings for SNMP management of the cluster (see “Configuring
SNMP settings using the CLI” on page 620 )
• parameters in the standard SNMPv2 MIB (see “Configuring the SNMP v2
MIB using the CLI” on page 621 )
• monitor, control, and trap community names (see “Configuring the SNMP
community using the CLI” on page 622 )
• SNMPv3 users (see “Configuring SNMPv3 users using the CLI” on
page 623 )
• SNMP managers (see “Configuring SNMP notification targets using the CLI”
on page 626 )
