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 

To configure SNMP for the Nortel SNA network, access the SNMP menu by 
using the following command:

From the SNMP menu, you can configure and manage the following:

•

general settings for SNMP management of the cluster (see 

•

parameters in the standard SNMPv2 MIB (see 

•
