Using an SNMP Interface

WORKING WITH PRISM MIB FILES

NOTE: Examples shown in this chapter use a browser from AdventNet or iReasoning. Procedural

details may vary with another browser, but the basic steps are the same.

NOTE: In the Prism system, the database accessed through the SNMP interface is the same

database as used by the EMS graphical user interface. There is therefore a similarity

between MIB objects and the parameters displayed in the EMS Web pages.

Figure 28 shows the features of a typical MIB browser.

As mentioned earlier, a MIB is a database specification containing definitions and

organization of information. The database consists of tables of objects used to

exchange information between a manager and agent. Database information is

exchanged using the following basic operations:

• GET—obtains an object value from the database.

• SET—sets the value of an object in the database.

• GET-NEXT—gets the next item in the database, be it the next type of object or

the next object of the specified type. This is especially useful for discovering

the presence of entries in dynamic tables.

• GET-BULK—requests multiple items in one message.

• TRAP/NOTIFICATION—sends an alarm in which a response can be sent by a

manager to an agent confirming receipt of the alarm.
