SNMP Basics

The following system components, though not SNMP-managed devices, receive SNMP support through ICS System Manager:

•System alarm processor (SAP) card

•Power supply modules

•Fans

•Chassis

SNMP Management Information Base

A Management Information Base (MIB) is a collection of information that is organized hierarchically. MIBs are accessed using a network management protocol such as SNMP. They comprise managed objects, which are identified by object identifiers.

A managed object (sometimes called a MIB object or an object) is one of any number of specific characteristics of a managed device. Managed objects comprise one or more object instances, which are essentially variables.

Using SNMP with MIB Variables

System MIB variables are accessible through SNMP as follows:

•Accessing a MIB variable—This function is initiated by the SNMP agent in response to a request from the NMS. The agent retrieves the value of the requested MIB variable and responds to the NMS with that value.

•Setting a MIB variable—This function is also initiated by the SNMP agent in response to a message from the NMS. The SNMP agent changes the value of the MIB variable to the value requested by the NMS.

Instead of defining a large set of commands, SNMP places all operations in a get-request, get-next-request, and set-requestformat. For example, an SNMP manager can get a value from an SNMP agent or store a value in that SNMP agent.
