Using Simple Network

Management Protocol

This chapter describes how to use Simple Network Management Protocol (SNMP). It includes the following sections:

■“About SNMP” on page 89.

■“SNMP MIB Files” on page 90.

■“MIBs Integration” on page 90.

■“SNMP Messages” on page 91.

■“Configuring SNMP on the ELOM” on page 92.

■“Managing SNMP User Accounts” on page 92.

About SNMP

The Sun server supports the Simple Network Management Protocol (SNMP) interface, versions 1, 2c, and 3. SNMP is an open technology that enables the management of networks and devices, or nodes, connected to the network. SNMP messages are sent over IP using the User Datagram Protocol (UDP). Any management application that supports SNMP can manage your server.

How SNMP Works

Utilizing SNMP requires two components, a network management station and a managed node (in this case, the ELOM). Network management stations host management applications, which monitor and control managed nodes.
